Match the model on your equipment label to the linked manufacturer documentation. The same code can mean different things across model families.

Quick answer

CH67 (alternate display EF) means the outdoor-unit fan is restrained, blocked, or its motor is failing, so the outdoor coil cannot reject/absorb heat. Power off, clear debris or snow around the outdoor fan only from outside, and call a technician if CH67 returns.

Severity: medium · DIY difficulty: easy

Safety

Stop at the breaker power-cycle and any plug-accessible checks (filters, remote settings, visible wiring). The outdoor unit's capacitor holds a lethal charge and the refrigerant circuit is both pressurized and (on R-32 units) flammable — opening panels or servicing the sealed system is licensed-technician work (EPA 608).

What H67 means

LG groups CH67/EF as outdoor unit fan errors, in contrast to CH10/E6 for the indoor fan: the outdoor fan is being restrained or its motor is not operating properly. LG's guidance is to check for debris or snow buildup around the fan components and remove it; if there are no visible issues, service is required. SplitAtlas lists CH67 as the outdoor fan restraint or outdoor fan motor fault group and Heat Pump Answers summarizes it as an outdoor fan motor lock - clear debris, then technician if it persists.

Code meaning varies by series

  • LG official: CH67/EF = outdoor unit fan issue (vs CH10/E6 = indoor fan)
  • SplitAtlas: Outdoor fan restraint or outdoor fan motor fault group
  • Heat Pump Answers: Outdoor fan motor locked - clear debris around the outdoor fan; persisting, call a tech

First checks before service

This page currently documents the safe reset triage. If the code returns, use the linked source manual or a qualified technician for code-specific diagnosis.

  1. 1. One-time fault event (power disturbance or transient sensor reading) common DIY

    Check: Power-cycle at the breaker/disconnect (or unplug for CPAP), restore, and run the system while watching for the code.

    Fix: If the code does not return after a full run cycle, the fault was transient — monitor, no repair needed.

  2. 2. Fault persists after a clean reset occasional pro only

    Check: If the code returns immediately or every session, note the conditions (startup, heating, after rain).

    Fix: A persisting code points at the component the manual assigns to this code — that repair is technician territory.
