Hotpoint Oven Error Code F2: Oven Temperature Too High... | appliancefaults.com

Technical Background:

The F2 error indicates the oven control board (MCU) has detected an over-temperature condition. The MCU receives temperature data from the oven temperature sensor (RTD) and compares it to the setpoint. If the temperature exceeds a pre-determined threshold, the MCU triggers the F2 error and may shut down the heating element. The voltage path involves the RTD sensor sending a resistance signal to the MCU, which interprets it as a temperature reading.

Symptoms:

The homeowner observes that the oven displays an F2 error code. The oven may be excessively hot, even when set to a low temperature, or may not heat at all. The error code appears intermittently or constantly.

Possible Causes:

Faulty oven temperature sensor (RTD).
Stuck relay on the control board.
Shorted wiring harness to the oven sensor.
Defective oven control board (MCU).
Excessive oven temperature due to thermostat malfunction.

Solution:

1

Disconnect power to the oven at the breaker panel.
2

Locate the oven temperature sensor (RTD) inside the oven cavity, usually at the rear.
3

Use a 1/4-inch nut driver to remove the screws securing the sensor.
4

Disconnect the sensor wires and test its resistance using a multimeter. A typical reading at room temperature (70°F) is around 1080 ohms. Refer to the service manual for specific values.
5

Inspect the wiring harness connecting the sensor to the control board for any signs of damage or shorts.
6

If the sensor and wiring are good, replace the oven control board. Ensure the new board is properly configured for the specific oven model.
7

Reconnect power and test the oven to ensure the F2 error is resolved.

Safety Warning:

Disconnect power to the oven at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. High voltage is present when the oven is powered on. Use caution when working around electrical components.

Prevention:

Regularly clean the oven to prevent excessive buildup of food debris, which can affect temperature regulation. Periodically check the oven temperature accuracy using an oven thermometer. Avoid using harsh chemicals when cleaning the oven, as they can damage the sensor.

Expert Tip:

Some Hotpoint ovens have a service mode. To access it, press and hold the Bake and Broil buttons simultaneously for 5 seconds. This will allow you to view error history and run diagnostic tests.

Frequently Asked Questions

•What is the typical resistance range for a functioning RTD sensor at room temperature?

At room temperature (approximately 70°F), a typical RTD sensor for a Hotpoint oven should read around 1080 ohms. However, always refer to the specific service manual for your model.

•How can I verify that the new oven control board is properly configured for my oven model?

The new control board usually has dip switches or jumpers that need to be set according to the model number. Refer to the installation instructions that come with the new board. If you can't find the instructions, you can typically find them online with the board's part number.

•If the RTD sensor tests within the correct resistance range, what is the next most likely cause of the F2 error?

If the RTD sensor tests good, the next most likely cause is a faulty oven control board or a short in the wiring harness between the sensor and the board. Carefully inspect the wiring for any signs of damage or chafing before replacing the control board.
