LG Dryer Faulty Gas Burner Valve Assembly

**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. 

How to Replace a Faulty Gas Burner Valve Assembly in a LG Dryer

If clothes are still wet after completing the dry cycle in LG dryer model DLG2602R, it is likely due to lack of heat. This is a common dryer issue that could be caused by numerous possible malfunctions.

Once determining there are no issues with the high limit thermostat, flame sensor, thermistor and ignitor, consider examining the gas burner valve assembly, which supplies gas to the dryer burner. A malfunctioning valve assembly won’t administer gas, which means the dryer won’t heat.

Before starting any dryer repairs, unplug it from the wall and turn off the gas supply valve. Never attempt a repair without wearing proper safety gear, such as work gloves and goggles. As with all technically difficult and potentially dangerous repair, this repair is best left to a
specialist.

Steps to Replacing Gas Burner Valve Assembly

  1. Pull LG dryer forward and away from laundry room wall. On the back of the appliance, unthread screws that secure the top panel to  dryer. Once screws are out, pull panel toward you, and lift it up and off dryer.
  2. Now, disassemble the control panel. (Before disconnecting wires, it’s a good idea to take a photo of all wire connections to assist in easily reconnecting them during reassembly.) Start detaching the wire harnesses from the back of the board. Once all wires are disconnected, take out the screws that hold the control board console to the dryer, and then pull console off front of dryer.
  3. With control board removed, disconnect the door switch located near the top center of the door frame. Next, open dryer door and
    unthread screws that hold front panel to lint screen housing. Once the screws are out, close the door and unthread screws at the top of the front panel. Then, carefully tilt front panel backward, and pull it up and off dryer.
  4. Now, remove control panel bracket off the dryer. First, locate dryer light bulb and disconnect wire harness running to it. Next, locate two wiring retaining clips on the back of the bracket. Take out the wires being held in the retaining clips. Then, remove screws holding the control panel bracket to the front of dryer, and pull bracket off dryer.
  5. Near the bottom of dryer, disconnect wire harness to the moisture sensor. Once the wires are separated, unthread screws that
    secure bulkhead to dryer and carefully lift off.
  6. Reach in between dryer floor and dryer drum to take drive belt off idler pulley and drive motor pulley.
  7. Grab drive belt on top of dryer drum and use to help guide drum out of dryer cabinet.
  8. With drum removed, locate gas burner valve assembly in the cabinet’s lower right hand corner. Disconnect wire harnesses running to valve assembly terminals. With a Phillips screwdriver, unthread screws that secure gas line to burner valve. Once screws are loose, carefully pull gas line off burner valve. Next, take out screws holding valve assembly to mounting bracket, and then take gas burner valve off mounting bracket and out of dryer cabinet.
  9. Before installing new valve, take the orifice off the old gas burner valve and place on new component. Once orifice is securely
    attached to the new gas burner valve assembly, proceed with installation process.
  10. Place gas burner valve assembly on mounting bracket, ensuring screw holes are lined up on bracket with screw holes on the valve
    assembly. Then, replace screws used to secure gas burner valve to mounting bracket. Next, align gas supply tube with burner valve, and insert tube into the valve. Once tube and valve are connected, rethread screws taken out earlier to secure the tube to the valve. To complete installation, reconnect gas burner wire harnesses to valve terminals.
  11. Before putting dryer back together, take a moment to check for any gas leaks. To do so, fill a spray bottle with soapy water, and turn  gas supply valve back on. Then, spray gas burner valve with soapy water. If any bubbles form, a gas leak is present, meaning the connection is not tight enough. At this point, turn off dryer’s gas supply, and try tightening the tube and valve coupling. Once you’ve adjusted the union, turn gas back on, and run gas leak test again. If no bubbles appear, the gas leak should no longer be an issue. If bubbles are still forming, DIY consumers should contact a dryer repair technician to further inspect.
  12. After testing for leaks and none are found, turn off gas running to the dryer, and start reassembling the dryer. Pick up dryer drum and carefully guide it into the dryer cabinet, ensuring the drum back sits on the drum rollers. Then, reach in between the drum and dryer floor to rethread drive belt on idler pulley and drive motor pulley. Make sure belt is installed in zigzag formation.
  13. Retrieve dryer bulkhead, and align with front of dryer. Then, secure part with screws taken out earlier. With bulkhead in place,
    reconnect moisture sensor wire harness, and light bulb wire harness.
  14. Now, reattach control board bracket. Once bracket is in place, pull door switch wire harness to front of dryer through one of the
    openings on the bracket. Then, snap wire into retaining clips on back of the bracket.
  15. Grab dryer front panel and line up with the dryer front. Before laying panel flush, reconnect door switch harness to door switch, and
    finish installing front panel. After adding screws to secure panel, open dryer door, and rethread screws that connect front panel to lint screen housing.
  16. Snap control panel back on dryer, and reattach screws removed earlier. Finish installing control panel by reconnecting wire harnesses that run to the panel back.
  17. Finally, reinstall the dryer’s top panel, plug in the dryer and turn on gas supply valve.

How to Replace Front Load Washer Tub Filter

**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. 

Replacing Tub Filter in Electrolux Front Load Washer

In the Electrolux washer model EWFLS70JSS, the tub filter — also known as a coin trap — is found inside the tub by the pump hose. The filter prevents foreign objects from entering the drain pump. If the coin trap is damaged and debris is able to bypass the filter, the washer may not drain properly, or the drain pump may sustain irreparable damage and will have to be replaced. A clogged tub filter can also impact the draining process.

When a washer drains slowly or not at all, the tub filter may be damaged or obstructed and needs to be replaced. Before disassembling the washing machine, unplug the appliance and turn off the hot and cold water supply valves. Safety should always be a priority during appliance repair, so please protect hands and eyes by wearing work gloves and goggles.

Instructions

  1. Begin by pulling the washer forward and away from the laundry room wall. Next, at the back of the unit, disconnect the hot and cold fill lines from rear panel and detach drain hose from wall. Then, start unthreading the screws holding the main top to the machine. Once screws are removed, pull top back a few inches, and then lift up and off the washer.
  2. Underneath main top, locate power cord wire harness. Disconnect harness by pushing down on locking tab and pulling wires apart. Then, pull green grounding wire off top edge of rear mounting bracket. Using needle nose pliers, push small plastic mounting tab (holding power cord wire) out of washer’s metal bracket.
  3. Loosen and remove screws securing rear mounting bracket to washer’s upper cabinet. Once top and back screws are removed, lift bracket off washer.
  4. Now, take out all screws holding main, rear panel to washer. After all screws are removed, locate drain hose on  back panel, and unthread screw securing drain hose retainer to panel. Then, kneel down near bottom left corner of back panel and remove screws securing washer’s control board to panel. Finally, lift main, rear panel up and off your machine.
  5. Take drive belt off back of tub by gently tugging on belt while rotating drive pulley.
  6. At this point, look under tub and behind washer’s control board to locate tub to pump hose. Once you see it, reach inside washer cabinet and place towel under hose to catch any water that spills when disconnecting hose from the tub.
  7. Once towel is in place, use pliers to release hose clamp securing hose to air chamber shaft. Then, pull hose off  air chamber shaft. Next, use screwdriver to loosen hose clamp screw, securing hose to tub opening. Once screw is loose, slide clamp down and pull hose off opening in outer tub.
  8. Reach inside hose and retrieve tub filter inside. Note: filter may be filled with foreign objects and covered in unrecognizable gunk. Shake debris out of filter.
  9. After inspecting old tub filter, use screwdriver to pry filter cover off damaged part. The new tub filter does not include a new cover, so you’ll need to use the old cover on the new filter. The cover is held in place by four locking tabs: disengage tabs with screwdriver and pull cover off damaged tub filter. Before putting cover on new tub filter, rinse it thoroughly with water and optionally, mild detergent.
  10. The new tub filter is now ready to be installed. First, position filter cover on top of the tub filter and push down to engage locking tabs. Then, slide tub filter into tub to pump hose. The tab on the filter should line up with small slot inside the hose. Once filter is in place, reinstall hose to tub opening. Slide hose clamp up the hose, and tighten its screw to secure hose to tub connection. Next, push hose onto air chamber shaft and replace  clamp to secure hose.
  11. With the new tub filter installed, start reassembling washer. First, take washer’s drive belt and loop it around the motor pulley. Then, while slowly rotating drive pulley, carefully stretch drive belt around it. After belt is installed, turn drive pulley in both directions a few times, ensuing drive belt stays on and pulley is not restricted by any obstructions.
  12. Align rear panel with back of washer and secure with screws removed earlier. After installing rear panel screws, reattach screws that secure control board to washer’s back panel. Then, replace drain hose retainer and rethread its screw to hold  component and drain hose in place.
  13. Line up rear mounting bracket with holes in washer frame and secure with mounting screws. Next, locate power cord wire and plastic retainer attached. Push retainer back into small opening in reinstalled rear mounting bracket. Reattach grounding wire to edge of mounting bracket, and reconnect power cord wire harnesses.
  14. Pick up main top panel and place on washer, leaving about an inch or two of space between panel front and washer front. Then, push panel forward to lock in place.
  15. Finally, reconnect fill lines to back of washer and reattach drain hose to wall. Next, reposition the washer against laundry room wall; plug in; and turn on hot and cold water supply valves.

Lawrenceville, Ga., April 30, 2019Encompass Supply Chain Solutions, Inc., a leading provider of Distribution, 3PL and 4PL solutions for a diverse range of finished goods and repair parts, today announced that Jayne Sutherst will join its IT team in the newly-established role of Digital Marketing Director.

In this position, Sutherst will be responsible for managing all aspects of Encompass’ digital presence, primarily its main ecommerce site encompass.com, client web portals, search engine optimization and online and social marketing.  She is tasked with enhancing the online experience and customer support for both B2B and B2C users.  Sutherst will be based at Encompass’ recently-opened distribution and administrative facility near Fort Lauderdale, Fla.

Sutherst joins Encompass from MAPEI – a worldwide producer of adhesives, thinsets and sealants for buildings – where she served as digital marketing manager. Among her many accomplishments, she led the redesign and strategic planning of MAPEI’s flooring installation product website, which drove 1 million unique visitors to the site within eight months of launch.

Sutherst has 15 years of experience in web development, ecommerce and online marketing for both B2B and B2C audiences. She has worked in corporate retail and agency environments, beginning her career with American Express as a multi-media instructional designer manager.  Sutherst earned an MBA in Marketing and undergraduate degree in International Business from Nova Southeastern University.

“With her extensive background in web design and product sales, we are confident Jayne is the perfect fit to lead and strengthen our ecommerce initiatives,” said Encompass President and CEO Robert Coolidge.

He said Encompass’ tremendous growth in the Home Appliance space, along with the company’s spike in hosting co-branded manufacturer consumer ecommerce solutions, necessitated additional support within its technology department.  Plus, since Encompass offers one-on-one call center service and counter sales at its facilities, it needed to ensure consistency across all customer touchpoints, said Coolidge.

“It’s critical for us to deliver online resources for service dealers, distributors, manufacturers and consumers that align with our call in and walk in experiences.”

Coolidge said Encompass in past years mostly only served repair servicers, warranty companies, retailers and other businesses involved in aftersales product support.

“Through manufacturer partnerships and our own marketing efforts, we are serving more consumers – some who have used service professionals and some ‘do-it-yourselfers’ who prefer making repairs themselves. They have found that we often have complex parts they can’t get from traditional ecommerce sites.”

Coolidge also said that while Encompass maintains counters/will call at each of its distribution facilities in Georgia, Florida and Nevada, electronic ordering accounts for a growing portion of company sales.

“Ecommerce continues to complement our increasing brick and mortar presence in the U.S.,” he said. “With strategic locations, we can offer next or two-day ground shipping to most of the country, which typically meets the needs of both our business and consumer customers who prefer delivery service.”

Accessing and Testing Microwave Door Switches

**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. 

WARNING : Disconnect the microwave from any power source before moving forward.

Microwaves include three switches located behind the control panel: primary, secondary and monitor switch all actuate to keep the microwave from cooking the kitchen while the door is open.

Accessing the Switches

  • Remove the two Phillips screws that hold grill in place on top of microwave. Remove grill and lay aside.
  • Locate and remove the one Phillips screw that holds the control panel in place.
  • Lift up control panel and gently pull toward you. This will provide access to the three switches.
  • Remove all wires from control board. All wires are different from each other and will only fit on the terminal they were designed for.
  • Use needle nose pliers to remove connectors from terminals that can’t be removed by hand. Gently squeeze  connector to release it from the terminal.
  • The last wire to remove is the ground wire, which is connected to the microwave frame. Set control panel aside.
  • Remove  access cover and set aside.

How To Test the Switches

  • Set the multimeter to OHMS to test the three switches.
  • Please note that the primary and secondary switches are tested with the door open. With the door open, place the multimeter leads on the connectors on the primary switch first. When closing the door, the multimeter should produce a beep if the switch is good.
  • Test the secondary switch in the same manner.
  • Test the monitor switch with the door closed. When opening the door, the meter should beep.
  • If appropriate beeps did not sound on any or all three of these switches, replace the switch.

These three switches serve mainly to keep the microwave from operating with the door open. The switches also deliver voltage to the diode and magnetron which heat the microwave. If the switches test positive, this further confirms that magnetron has failed and needs to be replaced.

It’s time to button up the microwave. For most people, this is as far as you may wish to proceed. There is an ever increased chance of suffering a powerful electrical shock from the high voltage capacitor, which retains a residual amount of electricity. It will need to be discharged before the magnetron and high powered diode can be accessed and replaced.

Route the control panel wires back through the appropriate slots in the access cover and reattach the cover to the microwave frame. Reconnect the ground wire first and then reconnect all other wires to their compatible terminals.

Push the control panel back in place and secure with its Phillips screw. With the door open, replace grill cover. Opening the door makes it easier to replace the grill. Secure with its two Phillips screws. Do not over tighten these screws as the grill is made of plastic and it could break or crack.
