LG CH 67 error code

What it means

CH 67 means the outdoor fan is being restrained or its fan motor is not operating properly. The outdoor coil cannot reject or absorb heat normally without that fan.

Urgency

Likely causes

1. Outdoor fan restraint or lock
2. Foreign material in the outdoor fan drive area
3. Snow buildup around the outdoor fan components
4. Outdoor fan motor fault

Homeowner fix

Turn the system off. Remove only leaves, loose debris, or snow outside the outdoor grille, then reset once. If CH 67 returns or the fan is damaged, stop using the unit.

When to call a pro

Call a licensed HVAC technician if CH 67 returns, the outdoor fan does not spin normally, or there is no obvious external blockage. Tell them LG identifies CH 67 as outdoor fan lock or outdoor fan motor fault.

Repair vs replace

Outdoor fan repairs are usually less than full replacement. Compare replacement only if a technician also finds major board, compressor, or refrigerant problems.
