How to reset error code on Frigidaire refrigerator?
On a Frigidaire LGUS2642LP2 refrigerator, you typically clear an error code by doing a power reset (unplug the refrigerator for 10 minutes, then plug it back in). If the code returns, it is reporting an active problem, so use the code meaning to guide the repair steps in the LGUS2642LP2 owner's manual.
- Unplug the refrigerator (or switch the breaker OFF).
- Wait 10 minutes to let the control board fully reset.
- Restore power and allow 5 to 10 minutes for the display to stabilize.
- If your model has an alert reset key, press and hold Clear Alerts for about 3 seconds.
- If the error comes back, move to troubleshooting based on the code.
An error code that returns after a reset usually points to a real condition such as a fan issue, temperature sensor (thermistor) problem, or a door not sealing.
- Check for heavy frost or ice buildup that could block airflow.
- Make sure both doors close freely and the gaskets seal on all sides.
- Confirm the refrigerator is level so the doors self-close correctly.
- If the issue involves cooling or airflow noise, inspect the evaporator fan area.
- If the issue involves water or ice, confirm the water filter is fully seated and flush.
| Symptom you notice | Likely area to check | Best next step |
|---|---|---|
| Warm fridge or freezer | Airflow, frost pattern, fan | Check for ice blockage; listen for fan operation |
| Intermittent temps | Sensor/thermistor | Compare displayed temp vs actual; inspect sensor wiring |
| Door ajar alarms or frost near door | Door alignment, gasket | Level cabinet; inspect gasket contact |
| Ice or water dispenser issues | Filter, supply, dispenser | Reseat filter; purge air; check supply valve |
Resetting clears the display, but it does not fix the condition that triggered the code. Using the code meaning helps you avoid food spoilage, prevent repeat icing, and reduce strain on the compressor and control board.

What are the most common issues with LGUS2642LP2?
The most common issues we see on the Frigidaire LGUS2642LP2 side-by-side refrigerator involve cooling performance (warm fridge or freezer), ice maker and dispenser problems, water leaks, and door sealing issues. Many of these symptoms trace back to airflow, defrost, filtration, or gasket wear; use the LGUS2642LP2 owner's manual for model-specific checks.
- Warm refrigerator section: restricted airflow, evaporator fan issue, or a temperature sensor problem
- Frost buildup on the back wall or poor cooling: defrost system trouble (often a defrost thermostat)
- Ice maker not making ice: ice maker module/mold issues, dispenser/auger problems, or water supply restrictions
- Water dispenser slow or tastes off: clogged water filter or air in the water line
- Water puddles under the unit: defrost drain restriction or water line connection seepage
- Doors not sealing well: worn or warped door gasket causing temperature swings and moisture
- Confirm controls are set near typical targets: 0°F freezer, 37°F fresh food.
- Make sure vents are not blocked by food packages.
- Replace the water filter on schedule; for this model, a common replacement is the refrigerator water filter WF3CB.
- Inspect door gaskets for gaps, tears, or hardened sections.
- Listen for the evaporator fan; a failed fan can cause warm temps and uneven cooling.
| Symptom | Commonly involved system | Example part on this model |
|---|---|---|
| Frost buildup, warm temps | Defrost | Refrigerator defrost bi-metal thermostat 5303918214 |
| Slow water flow | Filtration | Refrigerator water filter WF3CB |
| Door won’t seal | Door sealing | Refrigerator door gasket (white) 241786013 |
Catching these issues early helps protect food temperatures, reduces compressor run time, and prevents secondary damage like ice buildup, water leaks, or dispenser failures.

What does EF stand for on a Frigidaire refrigerator?
On the Frigidaire LGUS2642LP2 refrigerator, EF (often shown as SY EF or 5Y EF) points to a problem in the evaporator fan circuit, meaning the freezer evaporator fan is not running correctly or the control is not sensing it properly. Start by checking for ice buildup or airflow blockage.
- Unplug the refrigerator for 5 minutes, then restore power to reset the control.
- Listen for the evaporator fan in the freezer; it should run when the compressor is running and the door switch is closed.
- Check for heavy frost or ice on the freezer back wall (a defrost problem can stop airflow).
- Make sure vents are not blocked by food packages.
- Inspect door sealing; warm air leaks can cause frost that interferes with the fan.
| What you notice | Most likely issue | What to do next |
|---|---|---|
| No fan sound, warm freezer | Evaporator fan motor circuit fault | Check wiring connections; test fan motor and control output |
| Fan noisy or rubbing | Ice buildup or damaged fan blade | Defrost and clear ice; replace fan blade if cracked |
| Heavy frost on freezer panel | Defrost system problem | Check defrost thermostat and defrost components |
| Code returns after reset | Control or wiring issue | Inspect harness and connectors; consider control board diagnosis |
If troubleshooting points to a failed component, these model-matched parts are commonly involved:
- Refrigerator evaporator fan blade 5308000010 (fan airflow and balance)
- Refrigerator defrost bi-metal thermostat 5303918214 (helps prevent excessive frost that can block the fan)
The evaporator fan moves cold air from the evaporator through the freezer and into the fresh food section. When the fan circuit fails, temperatures rise, frost can build up, and the refrigerator may run longer than normal.
- Use the LGUS2642LP2 owner's manual for normal operating sounds, airflow guidance, and control display behavior.
- For code definitions and symptom matching, use Frigidaire refrigerator error codes.
