Amana Oven Error Code F10: Runaway Temperature Alarm... | appliancefaults.com

Technical Background:

The F10 error code in an Amana oven indicates a runaway temperature condition, meaning the oven temperature is rising uncontrollably. The Main Control Unit (MCU) monitors the oven temperature using a Resistance Temperature Detector (RTD). The RTD's resistance changes with temperature. The MCU reads this resistance and adjusts the heating element accordingly. If the MCU detects an abnormally high or rapidly increasing temperature, it triggers the F10 error and shuts down the oven. The voltage paths between the RTD and MCU must be intact and within specified ranges for proper operation.

Symptoms:

The Amana oven displays error code F10. The oven may overheat rapidly, even if set to a low temperature or turned off. The oven may continuously heat, even after reaching the set temperature. The control panel may become unresponsive.

Possible Causes:

Faulty oven temperature sensor (RTD).
Shorted wiring in the RTD circuit.
Defective oven control board (MCU).
Relay stuck in the closed position.
Insulation breakdown allowing heat transfer.
Incorrect oven temperature calibration.

Solution:

1

Disconnect power to the oven at the breaker panel. Verify 0V AC at the oven receptacle.
2

Locate the oven temperature sensor (RTD) inside the oven cavity. It is usually at the top. Use a 1/4-inch nut driver to remove the mounting screws.
3

Disconnect the RTD wires from the oven control board. The control board is typically located behind the control panel. Use a 5/16-inch socket to remove the control panel.
4

Using a multimeter, measure the resistance of the RTD. A typical reading at room temperature (70-75°F) should be around 1080-1090 ohms. Refer to the service manual for the exact specification.
5

Inspect the wiring harness connecting the RTD to the control board for any signs of damage or shorts. Repair or replace as needed.
6

Check the relay on the control board that controls the oven heating element. If it's stuck closed, replace the control board. Visually inspect the relay for damage.
7

If the RTD and wiring are good, replace the oven control board (MCU).

Safety Warning:

Disconnect power to the oven at the breaker panel before performing any troubleshooting. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental re-energization. High voltage is present in the oven circuitry.

Prevention:

Regularly clean the oven to prevent grease buildup, which can affect temperature readings. Periodically inspect the oven temperature sensor for damage. Check the door seal to ensure proper insulation and prevent heat loss.

Expert Tip:

Some Amana ovens have a service mode that allows you to calibrate the oven temperature. Consult the service manual for instructions on entering service mode and performing temperature calibration. This can sometimes resolve F10 errors caused by slight temperature inaccuracies.

Frequently Asked Questions

•What is the acceptable resistance range for the RTD sensor at different temperatures?

Refer to the Amana service manual for the specific resistance values at various temperatures. The RTD resistance changes linearly with temperature; the manual provides a chart.

•How do I test the oven control board to determine if it is the cause of the F10 error?

Testing the control board requires specialized knowledge and equipment. Check the relay and all the wiring connections. Check for corrosion. If the RTD is verified to be good, replace the board.

•Where can I find the Amana service manual for my specific oven model?

You can usually find the service manual online by searching for your oven model number followed by "service manual". Websites like AppliancePartsPros or RepairClinic often have downloadable manuals. Otherwise, contact Amana directly.
