Electrolux Range Error Code 4,5,6
Max Unlock Attempts Exceeded (Motor Door Latch)
Max Unlock Attempts Exceeded (Motor Door Latch) - Door latch motor exceeded maximum unlock attempts.
First step from the service manual
Set the oven up for a clean cycle. Does the latch motor turn? No: Check the voltage applied to the latch motor. If line to neutral, replace latch mechanism. If zero, replace electronic control board. Yes: Check the phase and lock switches.

What 4,5,6 means on a Electrolux range
Error codes 4, 5, and 6 on an Electrolux range all relate to a Max Unlock Attempts Exceeded condition for the motor-driven door latch system. This fault is triggered when the latch motor has attempted to unlock the oven door the maximum allowable number of times without successfully completing the unlock cycle. The door latch motor is a critical component of the self-clean system, responsible for mechanically securing and releasing the oven door during and after a high-temperature clean cycle. When the control board detects that the motor has reached its retry limit without confirming an unlocked state, it sets one of these fault codes to prevent further damage and alert the technician.
The door latch system relies on two key feedback components: the phase switch and the lock switch. These switches communicate the current position of the latch mechanism back to the electronic control board. If either switch fails to signal a successful unlock, the board commands the motor to retry. Repeated retries without confirmation exhaust the attempt limit and produce this fault. The issue may stem from a failed latch motor, a defective switch, or a lack of proper voltage reaching the motor circuit.
Diagnosis begins by initiating a clean cycle to observe whether the latch motor turns at all. If the motor does not move, voltage at the motor terminals must be checked. Line-to-neutral voltage present at the motor with no movement confirms a failed latch mechanism requiring replacement. Zero voltage at the motor points to the electronic control board as the source of the fault. If the motor does turn during the test but unlocking still fails, the phase and lock switches should be inspected for proper operation and continuity.

Common causes of 4,5,6
- 01
Failed Latch Mechanism
Part replacementThe latch motor receives proper voltage but fails to move or complete the unlock cycle, indicating a mechanically or electrically failed latch assembly. This is confirmed when line-to-neutral voltage is present at the motor terminals but the motor does not turn.
- 02
Faulty Phase or Lock Switch
Part replacementIf the latch motor turns but the control board never receives confirmation that the door has unlocked, one or both position switches (phase switch or lock switch) may be defective or misaligned. These switches provide the positional feedback that tells the board the latch has successfully moved.
- 03
Defective Electronic Control Board
Part replacementWhen the latch motor does not turn and voltage at the motor terminals reads zero, the electronic control board is not supplying power to the motor circuit. This points to a failed relay or control board output as the root cause.
- 04
Mechanical Obstruction in Latch Assembly
Wiring / connectionGrease buildup, food debris, or deformation of the latch mechanism from repeated high-temperature clean cycles can prevent the motor from completing its travel, causing repeated failed attempts and triggering the fault code.
