Driving Efforts to Repair vs. Replace

To repair or replace is one of the greatest quandaries regularly affecting the reverse logistics industry. Consumers are inundated with various formulas and advice on whether to repair the refrigerator that’s not cooling or the dryer that’s not heating – or upgrade to the latest model.

When the economy is flourishing, consumers tend to lean toward replacement. Their existing model suddenly seems obsolete when a flashier version hits the market, especially if the current unit is not functioning properly.

The most common rule of thumb is to opt for repair if the cost is less than 50% of the new purchase price. Underwriters follow a similar rule when determining whether to replace or repair a product under warranty. However, while financial considerations are certainly high priority, some businesses and consumers also place value on eco-friendly solutions to minimize the harmful impact of e-waste.

SourceToday reports that more than 40 million tons of e-waste are annually generated worldwide. By the year 2050, global e-waste production could reach 120 million tons annually if current trends continue. According to The World Health Organization (WHO), e-waste emits numerous toxic materials such as lead, cadmium, chromium, brominated flame retardants and polychlorinated biphenyls (PCBs). Humans get exposure to these toxins by inhaling fumes, as well as from accumulation of chemicals in soil, water and food.

Right to Repair

The service repair industry is currently benefiting from “right to repair” efforts at both the state and federal levels. Groups pushing to maximize repair opportunities claim some manufacturers make it nearly impossible to fix their goods so they can sell new products instead.

Proposed legislation typically requires manufacturers to provide service manuals and diagnostic software, as well as make replacement parts available to increase repair capabilities for DIY consumers and professional service techs alike. New laws are intended to both prevent e-waste and increase competition among repair providers.

Industry Developments

To meet demand, the repair industry continues to improve with new technology and operational processes. Some repair depots have employed advanced test equipment that passively tests circuit boards to determine out-of-tolerance conditions. This enables more detailed troubleshooting and helps make repairs more viable since costly, often hard-to-find test fixtures aren’t needed.

With software enhancements delivering real-time tracking throughout the repair cycle, automated status updates can be provided to keep customers/end users informed – minimizing time-consuming calls and update requests.

Repair Challenges and Solutions

Repair providers are not without their own unique challenges. They are constantly under pressure to reduce turn times and increase yield within constraints of shipping time and expense. They often have to compete against depots offering cheap flat rate pricing regardless of labor and part costs.

Additionally, not all repairs are equal. While some only require fast, less expensive “fluff and buff” service, others are much more complex, requiring additional time, effort and pricey components.

To combat these common issues, many depots have found creative ways to keep costs down to enable more economical repairs. Using parts harvested from non-repairable products is one way to offset costs of high-dollar components like circuit boards. Repairing such boards is also critical to maintaining a strong parts supply chain to increase repairs.

To simplify shipping to depot facilities, service providers are often partnering with freight carriers to offer convenient product drop off and pick up locations. Continually reviewing and negotiating favorable freight rates is another important way to control costs and help make repairs more financially feasible.

Assessing Repair Partners

There are several key factors to consider when selecting a repair partner. First, prior to engagement, it’s critical to outline specific services required, performance expectations and business rules. One of the most important aspects of this process includes determining the economical price point for repair, plus product disposition options when the maximum is exceeded.

Establishing metrics for repair yield, cost, turnaround time, quality and other indicators are necessary to adequately evaluate performance. Depots should be able to document each step of the repair process for accountability and then deliver extensive reporting to gauge performance. By measuring all facets of the repair operation, depots should be striving to continually improve and meet or exceed service level expectations.

Position for Success

With both strong financial and environmental cases to be made for repair, momentum is growing on the side of repair providers. Those leveraging new technology, highly-efficient practices and strategic pricing will be best positioned to take advantage of right to repair laws and succeed against competitors.

Replacing Freezer Temperature Control Thermostat in Frigidaire Refrigerator

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 freezer temperature control thermostat, or cold control thermostat, regulates the temperature inside the freezer compartment. When the thermostat senses the freezer is too warm or too cold, it cycles the compressor on and off. The control thermostat is found in the control housing inside the fresh food compartment of the Frigidaire refrigerator model FRS26R4CW.

The sensor bulb, which monitors the temperature, stretches from the control thermostat to the
freezer interior. If the freezer runs too cold or too hot, there’s a good chance the
temperature control thermostat has failed and is no longer switching the compressor on and off
at the appropriate time. Unfortunately, a damaged control thermostat cannot be repaired and
will need to be replaced.

Appliance Repair Safety Tips

  • Always unplug refrigerator and turn off its water supply before starting work to prevent electrocution injury.
  • Keep hands and eyes safe by wearing gloves and safety goggles during repairs.
  • Stop what you’re doing and contact an appliance repair specialist if ever a repair job feels unsafe.

Tools Needed

  • 1/4″ Nut Driver
  • Flat head screwdriver

Steps to Removing Control Housing Assembly from Refrigerator

  1. Open fresh food compartment door and either lower or remove top shelf. Once
    shelf is out of the way, unscrew refrigerator light bulb.
  2. At front of control housing assembly, depress water filter release button. When filter pops out, remove it.
  3. Using 1/4″ nut driver, unthread screw that secures water line cover to top and rear wall of  refrigerator. Then, carefully pull cover off wall and ceiling, and disconnect from back of control housing assembly.
  4. Now, unthread screws that hold control housing assembly to compartment ceiling and sidewall. There are several screws, so ensure all are removed, including the one behind the damper grill. Once all screws are removed, lower control housing and disconnect wire plug from ceiling.
  5. Next, pull out the two water lines that run to the back of the control housing. Some water
    may leak out of the lines, so have a towel nearby.
  6. Finally, pull out the temperature control sensor bulb from freezer compartment. Move control housing assembly to flat, sturdy work table.

Uninstall Freezer Temperature Control Thermostat

  1. Start uninstalling temperature control thermostat by removing control knob. To do
    so, insert flat head screwdriver behind knob and push off the control thermostat shaft.
  2. Next, remove control thermostat from mounting bracket by using flat head screwdriver to depress locking tab holding component in place. Then, lift thermostat up and disconnect wires running to it.
  3. Before completely uninstalling control thermostat, free the sensor bulb, which runs along side the damper control. To get to the part, pull top of damper control off control housing. Then, carefully slide sensor bulb out of the plastic installation tube.

Installing New Freezer Temperature Control Thermostat

  1. Take new control thermostat and straighten out sensor bulb. Then, thread bulb through plastic installation tube attached to side of damper control. Stop sliding sensor bulb forward once tip of the bulb reaches the end of the tube.
  2. Reinstall damper control by pushing it back onto control housing assembly.
  3. Insert rest of the sensor bulb into clips running along the inside of the control housing. Then, near the temperature control, bend the sensor bulb to fit the component back into mounting bracket.
  4. Before pushing control thermostat into bracket, reconnect wires to terminals. Then, use flat head screwdriver to pull back bracket locking tab while pushing down on control thermostat until the component locks in place.
  5. To complete installation, slide control knob onto thermostat shaft. Test knob out by twisting it around a few times to ensure it rotates freely.

Reinstalling Control Housing Assembly

  1. Begin installing control housing assembly by threading sensor bulb through opening near back of fresh food compartment. Then, insert control housing plug into refrigerator ceiling. Next, push water lines into back of the control housing assembly.
  2. Line up screw holes on control housing assembly with screw holes in fresh food compartment ceiling. Then, using 1/4″ nut driver, rethread screw closest to water filter housing. Once that screw is secure, reinstall the rest of the screws. Before finishing, insert screw near water lines and behind damper grill.
  3. Retrieve waterline cover and reinstall by inserting tabs on front of cover into slots on back of water filter housing. Then, push up on cover to insert locking tabs into the refrigerator ceiling. Finish installing cover by rethreading single screw holding it to rear wall.
  4. Slide the refrigerator water filter back into its housing. Replace fresh food compartment light bulb, and readjust top shelf.
  5. Finally, plug in the refrigerator and turn on water supply. Open refrigerator door and set control thermostat to desired temperature. Give some time for the new part to start working and then check to ensure the temperature is now working correctly.

LG Dryer Faulty Gas Burner Valve Assembly

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

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.
