LG Refrigerator Code 33: Relay Circuit Check

Medium · inspection needed

Code: 33
Appliance: Refrigerator
Brand: LG
Warranty: 30-day workmanship

What 33 means

Code 33 shows on LG refrigerators with an LED or LCD display in French door, side-by-side, top-freezer, and bottom-freezer styles, and it can appear as 33, Er 33, or E 33. The control reports a problem with the compressor relay, which is the part of the circuit that switches the compressor on. You may see the code with warm air in the fresh-food or freezer section, and the compressor may not be running when it should.

Common causes of 33

Compressor relay circuit on the control board
Wiring between the control and the compressor
Compressor start behavior

✓ One safe check you can try

1. Confirm the plug is seated and the outlet works. 2. Close both doors fully and clear anything keeping a door from sealing. 3. Keep the doors shut as much as possible to hold the cold. 4. Move frozen items to a cooler if the freezer starts to thaw. 5. Request service, because there are no owner repair steps for 33.

! Why to stop there

Code 33 gives the circuit, but we still need to separate a control board relay from wiring or the compressor.
We test before recommending parts and give you a written price first.
Repairs are backed by a 30-day workmanship warranty.

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.

3333 questions

Do I need to throw out food with code 33?

Only if it has warmed past safe temperatures. Check how the freezer feels and use a thermometer if you have one. When in doubt, move items to a cooler while you wait for us.

Why does my fridge sound silent with code 33?

A quiet cabinet can mean the compressor is not starting. Code 33 points to the relay that starts it, but we have to test the circuit to know whether the relay or something else is responsible.

Is it worth repairing?

Often, yes, if the cause is a relay or wiring. We tell you what we find and quote the repair in writing, so you can decide before any work starts.
