Electrolux Dryer Error Code 42

Error code 42 on an Electrolux dryer indicates a door closed sensing error. The dryer's control board is unable to confirm a valid door-closed signal from the door switch circuit. This can be caused by a defective door switch, wiring issues, or a fault in the main board's sensing circuit. The dryer will not operate until the fault is resolved.

No, you should not attempt to bypass or continue using the dryer while error code 42 is active. The error indicates the dryer cannot confirm the door is securely closed, which is a safety interlock condition. Operating a dryer with an unresolved door sensing fault could pose a safety risk.

Repair costs depend on which component has failed. A replacement door switch is generally an inexpensive part, typically in the range of $15 to $40 for the part alone. If the main control board is the cause, parts can range from $100 to $250 or more depending on the model. Adding professional labor charges can bring the total repair cost to anywhere from $75 to $350 or higher.

Start by inspecting the door switch and its wiring harness for damage, loose connectors, or broken wires. Use a multimeter to test the door switch for continuity when the actuator is pressed. If the switch and wiring check out, examine the door alignment and strike tab to ensure the switch is being physically actuated. If all these components appear functional, the main control board may need to be replaced.

A power reset may temporarily clear the error code, but it will return if the underlying fault in the door switch, wiring, or sensing circuit is not repaired. Resetting the dryer is a useful first step to rule out a transient signal glitch, but a persistent code 42 requires hands-on diagnosis of the door switch circuit.
