What CH67 Means
CH67 indicates a fan lock error, per LG's dehumidifier Help Library article - the fan isn't turning when it should be.
Common Causes of CH67
- Fan motor jammed or obstructed
- Fan motor itself has failed
🔧 One Safe Check You Can Try
Unplug the dehumidifier from the wall outlet, let it remain unplugged for 3 minutes, then restore power and see if it clears.
⚠ Why You Shouldn't Go Further Than That
- If a full reset doesn't clear CH67, LG says the unit will require repair service - the fan assembly is an internal component, and forcing a jammed fan by hand while the unit is plugged in is a real injury risk.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
