LG Air Conditioner CH67 Error Code

Outdoor fan blocked or faulty. Here is what it means and how to clear it, easiest fix first.

CH67
Moderate DIY

The outdoor unit's fan isn't turning properly. LG names snow, ice, leaves and other debris jammed against the fan as common causes, along with a failing fan motor, wiring or control board.

Some models show EF instead of CH67. LG says its error-code guide covers all models, so the exact code and its meaning can differ on yours; check your owner's manual.

Safety first: unplug the air conditioner (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG CH67

  1. Switch off the power

    Switch off the air conditioner at its breaker before going near the outdoor unit, and wait for the fan to stop completely.

  2. Clear debris and snow

    Wearing gloves, pull away leaves, branches, snow or ice from around the outdoor unit and from the fan guard. Don't poke tools through the guard or remove any panels.

  3. Reset the power at the breaker

    Switch off the breaker that feeds the air conditioner (some systems have separate breakers for the indoor and outdoor units, so switch off both). Wait about five minutes, switch the power back on and restart the unit to see if the code clears.

When to call a technician

If the fan is clear and the code returns, a technician needs to check the outdoor fan motor and its board.

Frequently asked questions

What does CH67 mean on a LG air conditioner?

The outdoor unit's fan isn't turning properly. LG names snow, ice, leaves and other debris jammed against the fan as common causes, along with a failing fan motor, wiring or control board.

Can I fix LG CH67 myself?

Often. The first steps above are safe checks a homeowner can do. If they don't clear CH67, the cause is likely a worn part that needs replacing.

What if CH67 keeps coming back?

A code that returns after a reset and the checks above usually means a part is wearing out. Note when CH67 appears (which cycle, how often) and have your model number ready; it helps a technician bring the right part on the first visit.
