LG Refrigerator Error Code F2 F3

The F2 F3 error code indicates a condenser fan motor fault. The control board has detected that the condenser fan, which moves air across the condenser coils to release heat, is not operating correctly. This can affect the refrigerator's ability to maintain proper temperatures. Diagnosis involves checking the fan motor voltage at connector CON8 using Test Mode 1.

Continuing to run the refrigerator with a condenser fan fault is not advisable. Without proper condenser cooling, the compressor can overheat, which may cause permanent damage to the sealed system. Food safety is also at risk if temperatures rise above safe levels. The issue should be diagnosed and resolved promptly.

Repair costs vary depending on the failed component. A condenser fan motor typically costs between $30 and $80 for the part, while a main control board can range from $100 to $250 or more. Adding professional labor, total repair costs generally fall between $100 and $400 depending on the diagnosis and your location.

Some causes are DIY-accessible, such as clearing debris from the condenser fan area or reseating a loose connector at CON8. However, replacing the condenser fan motor or the main control board requires disassembly and basic electrical knowledge. If you are not comfortable checking voltage readings or working around refrigeration components, a qualified technician is recommended.

A reset is the recommended first step and can clear the code if the fault was a temporary sensor or control glitch. However, if the underlying cause is a failed fan motor, damaged wiring, or a faulty control board, the error will return after the reset. The reset also allows entry into Test Mode 1, which is needed for proper diagnosis.
