Error Code: E42 Difficulty: Hard
Problem: Door sensing error.
How to Fix E42 Error (Step-by-Step)
- Disconnect the dryer from its power source and confirm the error stays cleared during a full test cycle.
- Access the door switch and latch assembly by removing the necessary panels.
- Visually inspect the wiring between the door switch and the main control board for any signs of damage, such as burns or breaks.
- Use a multimeter to test the continuity of the door switch. It should have continuity when the button is pressed and no continuity when released.
- If the door switch tests fine, the issue may be with the main control board’s door sensing circuit.
- Inspect the control board for any visible signs of damage. Replacement of the control board is often necessary if it is found to be faulty.
- Due to the complexity, it is recommended to have a qualified service diagnose and replace the main control board.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
