How to Fix Dryer Error

Open the door and inspect the latch assembly for physical damage.
Locate the door switch plunger.
Press the plunger manually while starting the dryer; if it starts, the door hinge is sagging.
If it does not start, unplug the dryer and remove the top panel/front panel to access the switch.
Test the switch for continuity with a multimeter.
Replace the switch if it shows no continuity when pressed.

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