Kenmore Range Error Code F3 E5

F3 E5 on a Kenmore range means the control board has detected a short circuit in the bottom oven temperature sensor circuit. The sensor is a resistive probe that monitors oven temperature, and a short causes it to send an out-of-range signal to the board. The range will not operate normally until the fault is diagnosed and corrected. The issue can involve the sensor itself, its wiring harness, or the connector.

It is not recommended to use the lower oven while F3 E5 is active. The error means the control board cannot accurately read the oven temperature, which removes a key safety and performance safeguard. Operating the oven without a functioning temperature sensor risks uncontrolled heating. Disconnect power and address the fault before resuming use.

Repair costs vary depending on which component is at fault. A replacement bottom oven temperature sensor typically costs in the range of $20 to $60 for the part alone. If a technician is needed, labor charges can add $75 to $150 or more depending on your location and the service provider. A control board replacement is the most expensive scenario, with parts and labor potentially ranging from $200 to $400 or higher.

Some steps are DIY-friendly, such as disconnecting power, opening the back panel, and reseating the sensor connector. If the connector is secure, testing the sensor with a multimeter for a short or zero resistance reading is a straightforward next step. Replacing the bottom oven sensor is a moderate repair that many technicians and experienced DIYers can perform. If the wiring harness or control board is at fault, the repair becomes more involved and may warrant professional service.

Unplugging the range or cutting power at the breaker for a few minutes may temporarily clear the error code. However, if the underlying fault in the sensor, connector, or wiring is still present, the F3 E5 code will return once the range is powered back on and the control board runs its diagnostics. A reset is useful for confirming whether the fault is intermittent, but it does not repair the root cause.
