GE Profile dryer shows E9 and may not start or may stop shortly after starting; sometimes associated with door issues.

Safety first: Unplug the dryer before working around the door switch wiring.

Step-by-step checks:

• Door closure: Ensure the door closes fully and latches firmly. Check the door strike on the door and the latch on the cabinet for damage or misalignment.
• Test door switch: Locate the door switch behind the front panel near the door opening. With the dryer unplugged, remove the front panel or top as needed to access it.
• Continuity test: Disconnect the switch wires and test the switch with a multimeter. When the button is pressed (door closed), the switch should show continuity; when released, it should be open.
• Replace if faulty: If the switch does not change state correctly, replace it with an OEM GE Profile door switch.
• Inspect wiring: Check the harness from the door switch to the main control board for pinched or broken wires and repair as needed.

Tip: A misaligned door can sometimes be corrected by gently adjusting the door hinges or strike.
