Range oven display shows F3 and will not heat

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Broken oven sensor, Unplugged sensor connector, Cut or burnt sensor wiring harness, Faulty control board sensor input

Safety first: Disconnect the range from mains power before removing the back panel or accessing the sensor.

Technician steps:

Locate the oven temperature sensor inside the cavity (usually at the rear wall).
Remove the mounting screws and gently pull the sensor forward to access the connector.
Test sensor resistance with a multimeter; an open circuit indicates a failed sensor.
Inspect the harness from the sensor to the control board for damage.
Replace the sensor if open; if wiring and sensor are good, replace the oven control board.
