LG Refrigerator Error Code 22: How to Fix It

The Logic Verdict

Listen for the clicking. This code means the compressor fan or evaporator fan is stuck or broken. If you hear a clicking noise, the fan motor is likely dead.

What It Means

The 22 code (often displayed as Er 22 or 22 E) indicates a problem with the Compressor Relay or the Fan Motor. The main board isn’t detecting the fan spinning or the compressor starting.

Common Causes

1. Failed Start Relay: The small device attached to the compressor has burned out.
2. Bad Condenser Fan: The fan next to the compressor isn’t spinning.
3. Dirty Coils: Massive dust buildup is preventing the fan from working.

Step-by-Step Fix

1. Clean the Coils: Pull the fridge out, remove the back panel, and vacuum the dust off the coils and fan.
2. Inspect the Fan: Ensure the fan blade spins freely and isn’t blocked by debris.
3. Listen: Plug the fridge back in. If you hear a “click-click” every few minutes but the compressor doesn’t hum, the Start Relay is bad.
4. Replace Relay: This is a very common failure. The part is cheap and plugs right onto the side of the compressor.
