LG lists Er 22 and Er 33 as compressor relay faults. The compressor may not start or run normally, so the fridge can lose cooling.

Grouped codes: 22 and 33.

Safety first: unplug the refrigerator (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG Er 22

Reset the power
Unplug the refrigerator or switch off its breaker for about 5 minutes, then restore power. Plug it straight into a wall outlet.
Keep food safe
Check temperatures with a thermometer and move food to a cooler if the fridge goes above 40°F (4°C).

When to call a technician
