Ranges and wall ovens: reading F-codes and F#E# codes (GE, Whirlpool family) and when a reset is safe

Oven F-codes point to a circuit: temperature sensor, door lock, keypad or control. GE ovens show F plus a number; Whirlpool-family ovens show F#E#. Both makers tell owners to clear the display, cut power at the breaker for a short time and watch whether the code returns. A code that returns is a real fault. An over-temperature code is a safety stop: do not keep using the oven.

Oven cooling fan keeps running after the oven is off (or never runs)

Electric and many gas ranges and wall ovens have a cooling fan that protects the controls, door and cabinetry; it keeps running after the oven is off until the controls area cools, and cannot be switched off. Running for a while after a long or hot bake is normal; running with the oven cold, starting at power-up or never stopping points to a fan thermostat stuck closed, a welded relay, a bad temperature sensor reading or a control fault. A fan that never runs is a safety issue because the controls overheat.

Replace the oven temperature sensor (RTD probe)

The oven sensor is a thin probe at the top rear of the oven cavity, held by two screws, with a plug just behind the wall. Test it first, then pull it forward, unplug it without losing the connector into the wall, and plug in the new one. Electric and gas ovens use the same approach for the sensor; no gas parts are touched.
