Troubleshooting LG Ice Maker

**NOTICE**
Due to the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

There are many reasons to choose an LG refrigerator, and the slimline ice maker systems found in many of the latest models are among the best. Fixing the ice maker isn’t a job that requires emergency refrigerator service — after all, what are those plastic trays for?  But most people prefer not to have to balance trays from the sink to the freezer without sloshing water on the floor.

When an LG refrigerator ice maker stops working, here are six likely culprits:

1. Water Inlet Valve

The electronically-controlled water inlet valve is used to supply water to the dispenser unit. To function properly, it should deliver a flow of at least 20 psi. When the psi falls below this level, the LG refrigerator may still produce water (at a slower rate), but will not supply ice.

Use a multimeter to check current flow and power levels. If the figure is under 20 psi, increase flow by turning the valve. However, if the fridge gains the right volume of water but still won’t make ice, a new water inlet valve is needed.

2. Water Filter

Water filters aren’t just for producing great tasting water free from impurities. They’re also required for maintaining a suitable flow of water. If there has been a noticeable change in the taste of your water and ice before the ice maker’s failure, this could be the reason.

The lifespan of a water filter is influenced by a host of factors ranging from frequency of usage, specific LG model, and natural home water supply hardness. As a rule, manufacturers recommend changing water filters every six months, and most refrigerators provide a signal when it’s time.

3. Ice Maker Power Switch

LG refrigerators use multiple components that are responsible for different parts and functions. Ice makers are part of a self-contained unit, meaning they can be switched off even when the fridge is on, so first check to ensure it’s in the on position.

However, the ice maker can stop functioning even when the switch is on. The ice maker can be reset either manually or automatically.  depending on whether the refrigerator uses a Twist/Flex Tray, Custom Cube, or Early Twist/Flex Tray so be sure to check the manual.

4. The Internal Temperature

For an ice maker to function correctly, it needs to reach a temperature of -4°F. It usually takes up to 24 hours for a newly-installed refrigerator to reach this temperature.  The internal temperature of the freezer section can be set higher at 19°F, which is why the ice maker may be the last component to function as it should. If the ice maker is set to a higher temperature, ice production will be limited at best and take a long time.

3. Ice Level Control Board

Some LG models are equipped with an infrared beam that detects quantity of ice in the ice bucket at any given time.  If the beam stops working due to lack of power or a mechanical fault, the refrigerator’s onboard technology cannot switch to ice making mode.

If the refrigerator is plugged in and receiving the right level of water without making any ice, this could be the issue. A professional refrigerator repair service could confirm this and change just the ice level control board instead of the entire ice maker.

6. Refrigerator Door

LG refrigerators only work when the door is shut. Once the fridge door opens, the ice and water dispenser automatically shuts off until the switch is fully closed. Even if the door shuts to a point where the onboard computer thinks it is shut, any issues with the latch will cause problems.

A multimeter test will check for continuity and defects to determine if the door switch should be replaced or the sealant just needs to be changed. In more severe cases, replacing the entire LG refrigerator door could be required. Still, it’s better than replacing the whole product.

Still Unsure?

If the ice maker is the only fault on an LG refrigerator, consult the manual to check any error codes, which can provide further insight and prevent a costly replacement.

Troubleshooting Samsung Flexwash

**NOTICE**
Due to the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

 

Fixing Problems with Samsung FlexWash Washing Machine

Trouble with a Samsung Flexwash washer?  Unfortunately, even the best clothes washers can suffer from faults or wear and tear. Instead of rushing to buy another washing machine, first try troubleshooting to potentially repair the unit and save time, money and hassle.

Depending the problem, you may still require a professional washing machine service. Nevertheless, an accurate diagnosis is the first step to repair. Following are some Samsung FlexWash troubleshooting tips that will hopefully help guide you to the right fix.

Washing Machine Won’t Turn On

When the FlexWash washer won’t even turn on, try these steps:

  • Confirm power outlet is gaining power by plugging something else into it. If the outlet is not producing power, check the home circuit fuse box.
  • Ensure power cord is working by using a multimeter unit. If the cord is dead, it must be replaced.
  • Test the door lock. This is the part that keeps the washer door shut during operation. If it’s not working properly and fails to latch, it will need to be replaced as the washer will not power on unless the door is securely closed.

Screen Shows Error Message

When the Samsung FlexWash onboard computer senses a problem, the machine won’t operate. In some cases, though, the washer is actually functioning properly. Try these steps to confirm an issue:

  • Unplug washer from power outlet for at least 10 minutes.
  • Turn power back on.
  • If it powers on, run test wash without any clothes or detergent.

These measures won’t always clear the two-character error code. However, if the error was caused by a simple mistake like the door not being shut firmly, this can help avoid unnecessary fixes.

Drum Won’t Spin

The FlexWash uses a direct drive motor without belts or gears, which means there are fewer components that can fail. While this does promote greater durability, the Samsung FlexWash can still have drum issues — the bearings may have rusted due to water
damage or there could be a blockage.

If the drum won’t spin, try to manually turn it by hand. If it feels tighter than it should, the added resistance may be due to a blockage. If you can hear something rattle in the drum, it could be a coin or other small item. Remove the back and lid off the machine to find what could be causing the issue. At the same time, check the bearings, which are located around the outer circumference of the drum.

The Door Won’t Open

If the door won’t open, there may be a blockage in the drainage filter. Alternatively, the FlexWash’s pump may have failed and the machine will need to be drained manually before the door can reopen. To do this, remove the drain hose and place it into a bucket or sink,
enabling gravity to drain the water out.

When a manual drain fails to fix the issue, the door lock is the next most likely source of problems. Remove the top part and EZ Drawer Dispenser before releasing the lock from inside. In most cases, a new door lock is required. However, it may be necessary to replace the
entire door, which is why the entire mechanism should be inspected first.

Washer Won’t Fill Correctly

The Samsung FlexWash is designed to handle large loads in minimal time. Achieving this requires a steady intake of water. If the washer isn’t filling up to the desired levels, try the following:

  • Confirm water valves for both hot and cold water are fully opened.
  • Ensure water supply is set to at least 20 psi.

If neither of these steps work, it’s likely time to call a professional technician.

It should be noted that the Samsung FlexWash is equipped with smart technology and is WiFi-enabled. Therefore, the Samsung SmartCare app can often diagnose issues before they are even noticed. Pay attention to the codes supplied and consult the owner’s manual to learn more.

How to Clean Refrigerator Condenser Coils

**NOTICE**
Due to the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

The modern refrigerator is a marvel of advanced and traditional technology. Developing the ability to keep food cold is one of the most important inventions of all time, so it can be devastating when the fridge stops working.

Sometimes a refrigerator will slowly stop cooling just enough because of dirty condenser coils. Condenser coils are part of the critical systems that maintain appropriate cold temperatures inside the fridge. When a layer of dust and household grime builds up on condenser coils, the system will overheat, preventing it from efficiently cooling the fridge or causing it to stop working.

Fortunately, cleaning condenser coils is not hard if you know what you’re doing and have the right supplies. Here’s a quick guide to cleaning refrigerator condenser coils and safely returning a fridge to tip-top condition.

Be Prepared to Repair

Know Your Condenser
Every refrigerator brand and model is a little different, but condensers for most are located underneath the fridge behind a kick plate cover or grate. To confirm, consult the refrigerator’s owner’s manual or parts guide, which can be easily found online if you no longer have the documentation. (Encompass posts schematics for most refrigerator models on its site.)

Collect Supplies
This is a fairly simple repair that doesn’t require many supplies.  Here is a list of suggested items:

  • Work Gloves
  • Screwdriver
  • Soft Bristle Brush
  • Vacuum with Edging Attachment
  • Shop Towels
  • Heavy Duty Sponge
  • Dish Soap

Getting Started

  1. Unplug Fridge Power Cable
    This is for your own safety; food will be fine for half an hour while the fridge door stays closed. Disconnecting the fridge from power will prevent shock and electrocution while cleaning the coils.
  2. Remove Condenser Cover
    In most cases, the cover will be located along the bottom of the front of the fridge. Check to see if it is screwed in or clipped to determine the tools and approach you will need to pop the cover open and access the condenser coils inside.
  3. Clean Cover
    Over time, it’s natural for the cover to get saturated with grease, spills and floor grime. Be sure to scrub it clean in the sink with soap and water or at least use a damp rag to remove as much build up as possible. At least moderately cleaning the cover is important to maintaining clean condenser coils and promoting healthy airflow through the fridge components.
  4. Straighten Any Bent Fins
    If the condenser coil fans have been knocked significantly out of place, try straightening any bent fan blades. This can noticeably improve performance of the condenser and fridge. However, only bend a piece of the fridge’s inner workings if you are confident about what you’re doing and the fridge is unplugged.

Cleaning the Fridge Condenser Coils

  1. Brush Away Lint
    With a soft-bristled cleaning brush, very gently sweep off the condenser coils to clear away dirt, dust and hair and other grime. The brush should be effective enough, but use a vacuum if necessary.
  2. Vacuum With Soft Brush Attachment
    Start with a soft brush attachment and gently sweep over the coils again, this time with the help of suction. Carefully move the vacuum head back and forth over the coils, paying special attention to crevices and spaces for extra dust to build up. Next, switch to the precision corner attachment. Use this to remove any remaining specs of dust or grime that might be insulating the coils from being kept cool.
  3. Reattach  Cover
    With the coils clean, replace the cover in the same way it was removed.

Testing Results

  1. Plug in Fridge 
    Turn the fridge back on, and let it start cooling. The true test of a working condenser coil is when the fridge stays icy cold over several hours throughout the day, so check back in from time to time.
  2. Use Small Shelf Thermometer
    The best way to identify problems with a fridge’s coolness level is to regularly monitor the temperature with a simple clip-in fridge thermometer. If you notice any changes, you can immediately start troubleshooting before a possible minor problem becomes major.

How to Replace Oven Door Switch

**NOTICE**
Due to the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

 

While the oven door switch may not seem to mean much for oven functionality, it actually is of some importance. First, it influences how the oven light works. For many ovens, the door switch turns on the light if the oven opens, and turns it off when it closes unless the oven light switch is on. Also, the door switch affects the cleaning function in that the oven won’t self-clean if the door switch has stopped working and doesn’t sense the door is closed when it is.

This post provides detailed instructions on replacing an oven door switch, which is a simple repair with an interesting step.

Gather Supplies

Find the correct replacement door switch for your oven by checking the owner’s manual for the part number.  Other supplies include:

  • Screwdriver – Phillips and flat head
  • Work gloves
  • Prop stick

Safety First

  • Disconnect Power
    Because this repair involves an electrical component, there is risk for dangerous shock. Be sure to cut power to the oven before beginning work. If you can’t reach the plug — very common with built-in ovens — turn it off at the breaker.
  • Put on Gloves
    This repair also involves handling potentially sharp surfaces inside the oven, so it is especially important to wear work gloves for protection.

Open Top

  • Open Oven Door
    Open oven door all the way to access the front of the door switch and the underside of the cooktop lip.
  • Remove Screws Beneath Cooktop Lip
    Underneath the front lip of the cooktop are two screws with heads pointing toward the floor. Unscrew them and set aside.
  • Carefully Pull Cooktop Forward
    Pull cooktop forward to free two hinge tabs at back of cooktop and lift up. It’s okay to wiggle and lift cooktop as you pull it free.
  • Lift and Prop Cooktop
    Once cooktop is free of  hinge tabs, lift up front of cooktop like a box lid. Use piece of wood or sturdy stick to prop it open, bracing on metal. Be careful not to damage oven insulation underneath.

Remove Existing Door Switch

  • Identify Door Switch
    The door switch is a small cylindrical part set into upper right or left corner of oven door aperture with wires through the back.
  • Disconnect Wires
    Remember which color of wire is on top, and then disconnect wires. Take a picture for help when reassembling.
  • Release Locking Tabs
    With flat-head / slot screwdriver, press down on metal locking tabs of door switch, allowing switch to loosen.
  • Pull Out Door Switch
    Pull door switch out through front of oven and set aside. Switch can be thrown away or e-recycled.

Install New Door Switch

  • Push New Switch into Place
    Slide new door switch into place through now-vacant hole in front of oven door aperture. Press until locking tabs click.
  • Connect Wires
    Reconnect wires in same way they were connected to existing door switch.

Reassemble Oven

  • Remove Prop and Lower Oven
    Reverse process to open oven top. Start by removing prop stick and gently lowering cooktop back onto oven body.
  • Fit Hinge Tabs Below Upper Control Panel
    While sliding oven cooktop backward, be sure tabs fit neatly underneath control panel.
  • Line Up Cooktop Sides
    Ensure sides of cooktop settle correctly over top of oven body and are not leaning to left or right.
  • Push Back Firmly
    Now firmly and carefully, push cooktop back into place. You may need to wiggle it and vary force to get firmly into place.
  • Return Mounting Screws
    Now return mounting screws underneath cooktop lip.

Test Repair

  • Restore Power
    Plug oven back in or switch breaker back on.
  • Open and Close Door
    Next, try opening and closing oven door with oven light manually turned off. Check if light comes on when door opened and turns off when closed.
  • Run Self-Cleaning Cycle
    Now, test run self-cleaning cycle. If oven runs complete cycle, repair was a complete success!

How to Replace Broken Dryer Buzzer

**NOTICE**
Due to the danger and complexity of electronic equipment repair, the following technical tip is intended for professional reference only. Please refer to manufacturer’s recommendations as Encompass does not guarantee the accuracy, reliability or safety of this information. 

 

Many people rely on dryer buzzer alerts to keep laundry moving efficiently, while others find the sound annoying and keep it turned off.  If you find the alerts more of a help than a hindrance, read on to see how easy it is to replace a broken Whirlpool-style dryer buzzer.

Get It Together

The first step to any appliance repair is to gather all necessary tools and the correct replacement buzzer. Be sure to double check the part number for your dryer’s make and model before placing an order. Here’s what you need:

  • Replacement Buzzer
  • Screwdriver (flat head and Phillips)
  • Hand Towel or Cloth
  • Work Gloves (optional)

Repair Steps

  1. Unplug Dryer — Because this is an electrical repair, start by unplugging the dryer. This prevents shock when changing out the electrical components.
  2. Pull Dryer from Wall — Move the unit away from the wall and/or turn it to have enough room to stand behind it while accessing the upper back panel.
  3. Open Back Panel — Remove the mounting screws attaching the back panel to the control panel housing and set aside. Use the towel to fully pull away the back panel as the edges can be sharp. Work gloves can also keep your hands safe from an accidental cut. Set the panel aside next to the screws.
  4. Remove Broken Dryer Buzzer — Take off the buzzer knob or button. Trace the button to the exact location in the back of the dryer. Different dryer models often place the buzzer in various locations, so this is the most reliable way to find the right part. You can also match it to the appearance of your replacement part.
  5. Disconnect Wiring Clip — Pull wiring clip free from existing, broken buzzer [you may need to press a release catch].
  6. Unfasten Mounting Screw(s) — The existing buzzer should be mounted with one or two screws, which need to be removed and set aside. Now, remove the buzzer and discard, or preferably recycle.
  7. Install New Part — Start by connecting the wiring clip to the back of the new buzzer, just as the previous buzzer was connected. This is easier to do while the buzzer is not yet fastened.
  8. Align New Buzzer — Align the new buzzer into place. There may be a second screw point or a small lip or clip that slots into a hole where the top of the buzzer should go. Make sure that one or both screw holes are aligned with the mounting points inside the control panel. Then, fasten the mounting screws firmly to hold new dryer buzzer in place.
  9. Return Knob & Reassemble Dryer — Finally, if you removed the knob or button, return it to the front of the dryer panel. With the new part installed, close the back panel, aligning it into place and ensuring the mounting screw holes line up with the dryer panel housing. Fasten the back panel mounting screws and push the dryer back toward the wall. Be careful with the dryer duct tubing, which will need to remain uncrumpled while you push the dryer.
  10. Test New Buzzer — Plug the dryer back in and set a short timed drying session to ensure the buzzer sounds.
