How to Fix LG Dryer Error CF

Problem: Clean Filter. A logic prompt indicating the lint filter must be cleaned.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.

Problem: No Heat (Gas) – Not a display code, but a system state. Thermal fuse tripped.

Unplug the dryer.
Remove the back panel or front ductwork to access the blower housing.
Locate the white thermal fuse on the blower housing.
Test for continuity. If open (no beep), the fuse has blown due to overheating (usually a clogged vent).
Replace the fuse and clean the vent.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.

Problem: No Heat (Electric) – Not a display code, but a system state. High Limit Thermostat tripped.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.

Problem: Motor Locked Error. The drum is overloaded or the motor is physically seized.

Open the door and remove some wet clothes (reduce load size).
Try to spin the drum by hand; it should offer resistance but move.
If the drum is stuck solid, check for objects wedged between the drum and bulkhead.
If drum moves but code persists, the motor windings or Hall sensor (if equipped) are bad. Replace motor.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
