Maytag Washer Error Code 4

Error code 4 on a Maytag washer indicates a door lock failure where the door-locked switch circuit is open after the cycle has already started. The control board tests the circuit approximately 90 seconds into the cycle and stops operation if it does not detect a closed circuit. The most common cause is a failed bi-metal device inside the door lock assembly.

No, you should not attempt to run the washer while code 4 is active. This fault indicates the machine cannot confirm the door is securely locked, and the control board halts the cycle for that reason. Running a washer with an unconfirmed door lock creates a risk of the door opening during operation.

If the repair requires only a new door lock assembly or bi-metal device, parts typically range from $20 to $80 depending on the specific model. Adding professional labor, the total repair cost generally falls between $100 and $250. If the fault is caused by a wiring issue rather than a failed part, the cost may be lower since no replacement component is needed.

Start by inspecting the bi-metal device in the door lock assembly, as this is the most frequently failed component. Also check the wiring harness and connectors leading to the door lock for breaks, corrosion, or loose terminals. If the bi-metal device or the door lock assembly tests as faulty, replacement is required to clear the code and restore normal operation.

A reset may temporarily clear the code, but it will return as soon as the washer reaches the 90-second test point in the cycle if the underlying problem has not been fixed. The fault is triggered by an actual open circuit in the door lock system, not a software glitch, so resetting alone is not a repair. The bi-metal device or door lock assembly must be inspected and repaired first.
