LG Refrigerator Error Code 22

Error code 22 on an LG refrigerator indicates a fan motor system abnormality in the CR (Cooling Room) compartment. The refrigerator has detected a problem with the fan motor's feedback signal, which could be caused by a loose or broken wire, a bad connector, or a failed motor. The refrigerator uses this feedback signal to confirm the fan is running properly, and when it cannot detect a valid signal, it logs code 22.

Continuing to run the refrigerator with error code 22 active is not recommended for extended periods. A non-functioning CR compartment fan can lead to inadequate cooling, which puts food safety at risk. It is best to address the fault promptly and move perishables to another cold source in the meantime if cooling has been significantly reduced.

Repair costs vary depending on what is causing the fault. If the fix is as simple as reseating a connector, there may be little to no parts cost, though a service call fee typically runs in the range of $75 to $150. If the CR compartment fan motor needs to be replaced, parts and labor combined generally range from $150 to $350 depending on the specific model and local labor rates. A control board replacement, if needed, will be on the higher end of that range or beyond.

Some causes of error code 22 are DIY-friendly, such as reseating a loose connector or thawing out ice that is blocking the fan. If the wiring harness is damaged or the fan motor itself has failed, replacing those components requires basic electrical knowledge and comfort working inside the refrigerator cabinet. If you are unsure about testing motor resistance or handling wiring connectors, a qualified appliance repair technician is the safer option.

A power reset may temporarily clear the error code display, but if the underlying fault with the fan motor, wiring, or connector is still present, the code will return once the refrigerator resumes normal operation. A reset is useful as a first step to confirm whether the fault is intermittent, but it does not repair the root cause. The fan motor feedback circuit must be inspected and repaired to permanently clear the code.
