Hotpoint Oven Error Code F1 — Electronic Oven Control (EOC) Failure
What this means
The F1 error on Hotpoint ovens and ranges indicates the Electronic Oven Control (EOC) has an internal failure. The EOC is the main control board that manages oven temperature, bake and broil operations, and the display. This code typically means the control board itself needs replacement, though it is worth checking the oven temperature sensor first since a shorted sensor can mimic an EOC failure.
Step-by-step fix
4 stepsReset the oven
Turn the oven off using the control panel. Go to the circuit breaker and turn off the oven circuit for 2 minutes, then turn it back on. This resets the EOC and can clear a false F1 error.
If F1 returns immediately after power is restored, the control board is almost certainly faulty.
Test the oven temperature sensor
Disconnect power at the breaker. Locate the oven temperature sensor probe — it enters the oven cavity from the back wall. Disconnect the sensor wires at the control board and measure resistance. At room temperature, a good sensor reads approximately 1,080–1,100 ohms.
You can also measure resistance at the sensor connector inside the oven to isolate the sensor from the wiring.
Inspect the wiring harness
Check the wiring between the sensor and the EOC for damage, pinched wires, or burnt insulation. A short circuit in this harness can cause an F1 code.
Pay special attention to where wires pass through the oven chassis — vibration and heat can cause insulation to wear through.
Replace the EOC if sensor is fine
If the sensor reads correctly and the wiring is intact, the EOC board needs replacement. Remove the rear panel screws from the control panel area, disconnect all wire connectors from the old board, and transfer them to the new board.
Label each wire connector with masking tape before disconnecting. Take a photo of the board layout as a backup reference.
When to call a professional
If you are uncomfortable working around 240V oven wiring or if the replacement EOC also shows F1, call a professional — there may be a deeper wiring fault.
