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.
What to Check Next on This Electrolux Dryer
Focused repair path: dryer airflow, heating, motor, sensor, and control checks. Do not treat the fault as reset-only if it keeps returning; use the failed function to choose the next test.
- Disconnect power before opening panels, then confirm whether the Electrolux dryer repeats the same code after a clean reset.
- Match the symptom to the part of the cycle or function that fails: fill, drain, heat, cool, spin, latch, ignite, fan, sensor, or control response.
- Inspect simple causes first: airflow, water supply, drain path, door closure, filter, venting, wiring connectors, and visible damage.
- Use meter testing or service diagnostics before replacing electronic controls, because wiring, switches, sensors, and loads can mimic board failure.
- Use the complete Electrolux dryer model number from the appliance tag before ordering any model-specific part.
Check, inspect, clean, test, measure, remove, reconnect, clear, and replace parts only when the symptom supports that path. If these checks point toward a part, verify the complete Electrolux model number from the appliance tag before ordering.

When It’s Better to Replace Than Repair
Dryer repairs are often worth it for small parts, but repeated heating, motor, drum, or control failures can point toward replacement.
Confirm gas vs electric, venting, voltage, doorway clearance, and laundry-space dimensions before ordering.
