Kenmore Range Error Code F5 E4

The F5 E4 error code on a Kenmore range indicates a latch switch fault. The oven door latch assembly includes one or more switches that communicate the latch position to the control board. These switches tell the board whether the door is fully latched (as required during a self-clean cycle) or in an intermediate or unlocked position. When the control board receives a signal that is out of the expected range or fails to detect a proper switch transition, it sets the F5 E4 fault and typically halts or prevents self-clean operation.

The latch switch system works by completing or interrupting a circuit as the latch motor drives the latch bolt into position. There are usually two switches involved: one that confirms the unlatched position and one that confirms the fully latched position. If either switch has a faulty contact, is misaligned, or has a wiring issue, the board cannot confirm the correct latch state. This fault can appear when starting a self-clean cycle, during the cycle itself, or when the oven attempts to unlatch at the end of a cycle.

The first diagnostic step is to enter the range's diagnostic mode and manually open and close the oven door while observing the display. A functioning door switch should cause the display digit to toggle, confirming the switch is operating. If the digit does not change, the fault is in the switch itself, its wiring harness, or the connection at the control board. Common culprits include a worn or burned switch contact, a broken wire in the harness near the latch motor, or a latch motor that is not fully driving the bolt into position to actuate the switch.
