What 22 Means
A 22 code indicates a compressor relay problem, the same category of fault as code 33 on LG's error-code list, and LG states there is no troubleshooting available for it.
Common Causes of 22
- Compressor relay has failed
- Wiring to the compressor relay is damaged
🔧 One Safe Check You Can Try
There is no owner-level step for this code; it's an electrical fault in the compressor's starting circuit, and LG documents no home fix.
⚠ Why You Shouldn't Go Further Than That
- This is high-voltage compressor-circuit work, not a filter or fan check - LG gives no home troubleshooting path for a reason.
- A compressor that can't start reliably because of a relay fault risks additional strain on the compressor itself the longer it's left running intermittently.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
