Direct answer
On the covered LG dehumidifier, CH 67 means a fan lock error — LG's own wording. First, unplug the dehumidifier from the wall outlet.

Match every character and the exact product
ReversiblePhotograph the complete display and product label. This record covers CH 67 on LG dehumidifiers with a digital display. Every code on LG's list is prefixed CH.
Preserve the failure state
ReversibleUnplug the dehumidifier from the wall outlet. Record the operating stage, recent change and what still works before clearing the message.
Correct only the documented fault domain
ReversibleLeave it unplugged for 3 minutes, then restore power. Do not borrow a reset or meaning from a similar code, product or model year.

What does CH 67 mean on a LG dehumidifier?+
a fan lock error — LG's own wording.
Can I reset CH 67 without fixing the cause?+
A reset may hide the display temporarily but does not correct the documented fault. Record the code and complete only the safe checks first.
Why is the complete model number required?+
Manufacturers reuse characters across platforms. The model number determines which official table, controls and service boundary apply.
When should I stop?+
If the code returns after LG's own 3-minute reset, the unit requires repair service.
