LG Refrigerator Code 22: Compressor Relay

Medium · inspection needed

Code: 22
Appliance: Refrigerator
Brand: LG
Warranty: 30-day workmanship

What 22 means

This code appears on LG refrigerators with an LED or LCD temperature display, including French door, side-by-side, and top- or bottom-freezer styles, where it may show as 22, Er 22, or E 22. It means the control has found a problem with the compressor relay, the switch that starts the compressor. The owner sees the code, and the refrigerator and freezer may warm up because the cooling cycle is not starting normally.

Common causes of 22

Compressor relay on the main control board
Compressor start wiring and connector
Whether the compressor itself is trying to start

✓ One safe check you can try

1. Check that the refrigerator is plugged in firmly and the outlet has power. 2. Make sure both doors are fully closed and not held open by packages. 3. Move perishable food to a cooler if the interior is warming. 4. Do not open any back or side panels. 5. Request service, because this code has no owner repair steps.

! Why to stop there

The code names the relay circuit, but we cannot tell from outside whether the relay, wiring, or compressor is involved.
We test the start circuit before quoting a written price.
The sealed system is never opened during this check.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

2222 questions

Can I reset code 22 myself?

The manufacturer lists no owner steps for this code, so we recommend service rather than repeated resets. Check the plug and doors, protect your food, and call us.

How fast will food spoil with code 22?

That depends on whether the compressor is running at all. Keep doors closed and check temperatures, and move food to a cooler if the fridge feels warm for several hours.

Is code 22 the same as code 33?

LG lists both as a compressor relay problem. They may point to the same circuit, so we test the relay and start wiring for either one and explain what we find before any work.
