Frigidaire Range Error Code F050

F050 indicates that the oven relay board is unable to read the status of the door switch or the MDL (motor door lock) switch due to an analog-to-digital conversion error. The board is receiving signals that fall outside the expected range and cannot determine whether the door is open, closed, or locked. This is typically caused by a failing relay board, a faulty switch, or a wiring connection problem.

It is not advisable to continue using the range while this code is active. The F050 fault means the control system cannot reliably read the door or door lock switch status, which could affect the safety interlock functions of the oven, particularly for self-clean cycles. Have the range diagnosed and repaired before resuming normal use.

Repair costs depend on which component has failed. If only wiring or a switch needs attention, parts costs are relatively low, typically in the range of $15 to $60 for a replacement switch. If the relay board requires replacement, parts alone can range from $80 to $200 or more depending on the model, with additional labor costs if a technician performs the repair.

Sometimes. Clearing the error and cycling power two or three times is the recommended first step. If the fault is intermittent or caused by a temporary power fluctuation, the code may not return. However, if F050 comes back consistently after power cycling, a component failure is present and the relay board will likely need to be replaced.

Start by clearing the error code and cycling power to the range several times to see if the fault is persistent. If it returns, inspect the wiring harness connectors at the door switch, MDL switch, and relay board for corrosion or looseness. If the connections look good and the error persists, the relay board is the most likely component to replace. Testing the door and MDL switches with a multimeter can rule them out before replacing the board.
