LG EF error code

What it means

EF is an alternate display for the outdoor fan restraint or outdoor fan motor fault group. The outdoor unit may stop because it cannot move air through the outdoor coil safely.

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 EF returns or the fan is damaged, stop using the unit.

When to call a pro

Call a licensed HVAC technician if EF returns, the outdoor fan does not spin normally, or there is no obvious external blockage. Tell them LG groups EF with outdoor fan lock.

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.
