Whirlpool Oven Error Code F3 E0: RTD Sensor... | appliancefaults.com

Technical Background:

The F3 E0 error code indicates a problem with the oven temperature sensor, also known as the Resistance Temperature Detector (RTD). The RTD sends a signal to the Main Control Unit (MCU) indicating the oven's internal temperature. The MCU uses this information to regulate the heating elements. The F3 E0 error suggests the MCU is receiving an illogical or out-of-range reading from the RTD.

Symptoms:

The oven displays an F3 E0 error code on the control panel. The oven may not heat properly, or the temperature may be inaccurate. The oven may shut off unexpectedly.

Possible Causes:

Faulty oven temperature sensor (RTD)
Wiring harness issue between the RTD and the control board
Loose or corroded wire connections
Defective oven control board (MCU)
Incorrect oven temperature calibration
RTD sensor touching the oven wall

Solution:

1

Disconnect power to the oven at the breaker panel.
2

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

Disconnect the RTD sensor wires from the oven's wiring harness. Use a 1/4-inch nut driver if necessary to remove mounting screws.
4

Set your multimeter to the resistance (Ohms) setting. Test the RTD sensor resistance. At room temperature (approx. 70°F), it should read around 1080-1100 Ohms.
5

Check the wiring harness and connectors for any signs of damage, corrosion, or loose connections. Use a wire brush or contact cleaner to clean corroded connections.
6

If the RTD resistance is significantly off or reads open/shorted, replace the RTD sensor. Part numbers vary; consult your model number.
7

If the RTD tests good and the wiring is intact, suspect a faulty oven control board. Replacement may be required, but consult with a qualified technician for advanced testing.

Safety Warning:

Disconnect power to the oven at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. Some components may retain a high voltage charge even after power is disconnected.

Prevention:

Periodically inspect the oven's wiring harness for any signs of damage or wear. Avoid harsh cleaning chemicals near the RTD sensor. Ensure the RTD sensor is properly positioned and not touching the oven wall.

Expert Tip:

Many Whirlpool ovens have a diagnostic mode. To access it, simultaneously press and hold the Bake and Broil buttons for 3 seconds. This may allow you to run a sensor test or view stored error codes before clearing them.

Frequently Asked Questions

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

The RTD resistance increases with temperature. Refer to the oven's service manual for a resistance chart correlating temperature and resistance. Online resources like AppliancePartsPros.com often have these charts as well.

•How do I calibrate the oven temperature after replacing the RTD sensor?

Oven temperature calibration procedures vary by model. Typically, you access the calibration setting through the control panel. Consult the user manual for specific instructions, or search online for instructions specific to your model number.

•What are the voltage readings I should expect on the wiring harness to the RTD sensor?

The RTD sensor is a passive device and doesn't have a voltage reading. The control board sends a small current through the sensor to measure its resistance. Testing for voltage directly on the RTD wires is not recommended and will not provide useful diagnostic information. Focus on resistance measurements.
