Code: CH67
Appliance: Dehumidifier
Brand: LG
Warranty: 30-day workmanship

What CH67 means

CH67 on an LG dehumidifier means the control has detected a fan lock error: the fan that moves room air across the coil is not turning as it should. Without airflow the dehumidifier cannot pull moisture from the room, so it stops and holds the code. The same characters show up on air conditioners as an outdoor fan code, which is a different appliance with different parts, so keep the two apart. On a dehumidifier the cause may be something rubbing the fan, or the fan motor or its control.

Common causes of CH67

Obstruction or debris touching the fan
Fan motor that is slow to start or stuck
Fan control circuit

✓ One safe check you can try

1. Unplug the dehumidifier. 2. Look at the air intake and outlet and remove any visible obstruction without reaching inside. 3. Leave it unplugged for 3 minutes. 4. Restore power and run the unit again. 5. If CH67 returns, stop using it and schedule a visit.

! Why to stop there

We find out whether the fan is physically blocked or the motor and control are the issue.
We check that the fan spins freely and starts on command.
Once it runs, we confirm it holds steady airflow before we finish.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

CH67CH67 questions

Does CH67 mean the fan motor is bad?

Not necessarily. It means the fan is locked or not turning as expected. Something may be touching it, or the motor or its control may be the cause. A test tells us which.

Is CH67 on an air conditioner the same?

The characters match, but there it refers to the outdoor fan of an air conditioner. A dehumidifier is a separate appliance, so the advice here applies only to dehumidifiers.

Can I open the dehumidifier to check the fan?

We would not. Stay outside the housing and only clear what you can see from the grille. Opening the unit puts you near wiring and a sealed system, so leave that to us.
