How to reset error code on Frigidaire refrigerator?
On the Frigidaire LGUS2642LE2 side-by-side refrigerator, we clear many error codes by doing a power reset (unplug for 10 to 15 minutes, then restore power). If the code returns, the refrigerator is detecting an active problem (often a fan, sensor, or defrost issue) that needs troubleshooting, not repeated resets; use the LGUS2642LE2 owner’s manual for model-specific alert and control steps.
- Unplug the refrigerator or switch OFF the circuit breaker.
- Wait 10 to 15 minutes to let the control board fully reset.
- Restore power and allow a few minutes for the display to stabilize.
- If you have a “Clear/Reset” style alert key on the control panel, press it once after power is restored.
- Confirm the doors are fully closed and the door seals are making full contact.
A returning code means the control is still seeing the fault. These checks solve the most common causes:
- Listen for the evaporator fan; a stalled fan can trigger cooling-related errors.
- Look for frost or ice buildup that can block airflow (especially at the back of the freezer).
- Verify the refrigerator is level and the doors seal on all four sides.
- If you recently changed the filter, make sure it is fully seated and flush.
- If temperatures are unstable, a sensor (thermistor) or defrost component may be involved.
| Symptom you notice | What it often points to | Example part for this model |
|---|---|---|
| Warm temps, fan noise changes | Evaporator fan issue | Refrigerator evaporator fan blade 5308000010 |
| Frost buildup, warming, intermittent cooling | Defrost system issue | Refrigerator defrost bi-metal thermostat 5303918214 |
| Temps swing, false alarms | Temperature sensing issue | Refrigerator temperature sensor 240597220 |
Resetting clears the display, but it does not fix the condition that triggered the code. Addressing airflow, door sealing, and temperature sensing prevents food spoilage, repeat alarms, and unnecessary strain on the compressor.

What are the most common issues with LGUS2642LE2?
The most common issues we see with the Frigidaire LGUS2642LE2 side-by-side refrigerator involve cooling performance, ice and water dispensing, frost buildup, and door sealing. Many of these problems trace back to airflow (evaporator fan), defrost components, water filtration, or a worn door gasket.
- Not cooling well or warm spots: restricted airflow, evaporator fan issue, or a temperature sensing problem
- Frost buildup on the back wall or in the freezer: defrost system trouble (thermostat, heater circuit, airflow)
- Ice maker not making ice: ice maker module issues, frozen fill path, or water supply/filter restriction
- Water dispenser slow or not dispensing: clogged filter, air in the water line, or dispenser-side issue
- Doors not sealing, moisture, or condensation: gasket not sealing, door alignment, or overpacked shelves/bins
- Confirm settings: freezer near 0°F and fresh food near 37°F.
- Listen for the evaporator fan: you should typically hear it running when the compressor is on.
- Check for heavy frost behind the freezer rear panel (a strong defrost clue).
- Inspect door gaskets for gaps, tears, or hardened sections.
- If water or ice is weak, replace the filter and purge air from the dispenser.
| Symptom | Commonly involved part | Example part for this model |
|---|---|---|
| Weak water flow, bad taste/odor | Water filter | Refrigerator water filter WF3CB |
| Frost buildup, warming | Defrost thermostat | Refrigerator defrost bi-metal thermostat 5303918214 |
| Poor airflow, warm fridge | Evaporator fan blade (and motor if applicable) | Refrigerator evaporator fan blade 5308000010 |
| Door not sealing, sweating | Door gasket | Refrigerator door gasket (white) 241786013 |
Cooling, ice production, and water dispensing all depend on stable temperatures and good airflow. A small issue like a leaking gasket or a restricted filter can force longer run times, cause frost problems, and reduce ice output.
Use the owner's manual for control settings, normal operating sounds, and care steps. For ice maker and water dispenser troubleshooting patterns, our DIY guide on how to replace the water filter in a Frigidaire refrigerator is also a strong match for this model.

What does EF stand for on a Frigidaire refrigerator?
On the Frigidaire LGUS2642LE2 side-by-side refrigerator, EF (often shown as SY EF or 5Y EF) points to a problem in the evaporator fan circuit, meaning the refrigerator is not sensing normal evaporator fan operation that moves cold air through the compartments.
- Make sure the doors fully close and the door seals are making full contact all the way around.
- Listen for the evaporator fan: it typically runs when the compressor is running and the door switch is closed.
- Check for heavy frost or ice buildup on the back wall inside the freezer (airflow restriction).
- Power reset: unplug the refrigerator for 5 minutes, then restore power and recheck.
- If the code returns, inspect wiring connections to the fan and control (loose plug, pinched harness).
| What’s happening | What it usually means | Typical fix |
|---|---|---|
| Fan is silent and no airflow | Failed evaporator fan motor or seized fan | Replace fan motor or clear obstruction |
| Fan runs but code returns | Intermittent wiring, connector, or control issue | Reseat connectors, inspect harness, test control |
| Frost blocks vents | Defrost system problem | Diagnose defrost components and airflow |
| Door not sealing | Warm air intrusion causing frost and poor airflow | Adjust door, clean/reshape gasket |
If you confirm an airflow or fan-related issue, these model-matched parts are commonly checked during diagnosis:
- Refrigerator evaporator fan blade 5308000010 (damaged blade can cause noise, wobble, or poor airflow)
- Refrigerator defrost bi-metal thermostat 5303918214 (if frost buildup suggests a defrost problem)
The evaporator fan is what distributes cold air. When the fan circuit is not operating normally, temperatures can rise in the fresh food section, ice production can drop, and frost can build up, which can lead to more cooling problems.
We recommend following the model-specific diagnostics and error code guidance in the LGUS2642LE2 owner's manual. For installation-related checks that can affect operation (leveling, door sealing, power and water setup), use the LGUS2642LE2 installation guide.
