Whirlpool AccuBake Oven Temperature Sensor W10833885 vs... | appliancefaults.com

Technical Background:

Whirlpool AccuBake ovens use a resistance temperature detector (RTD) sensor to monitor oven temperature. The oven control board (MCU) sends a small DC voltage through the sensor. The sensor's resistance changes with temperature, altering the voltage returned to the MCU. The MCU uses this voltage to control the oven's heating elements. Incorrect sensor readings due to a faulty sensor or wiring cause temperature control problems.

Symptoms:

The oven either overheats, underheats, or takes an excessively long time to preheat. Food may be burnt or undercooked. You may also see error codes related to the oven temperature sensor.

Possible Causes:

Faulty oven temperature sensor (RTD).
Wiring harness damage or loose connections.
Malfunctioning oven control board (MCU).
Incorrect oven temperature calibration.
Improper oven venting or airflow.
Using an incorrect or non-OEM replacement sensor.

Solution:

1

Disconnect power to the oven at the breaker panel. Verify no voltage with a multimeter.
2

Locate the oven temperature sensor, usually at the rear of the oven cavity.
3

Disconnect the sensor wires from the oven control board. Note the wire colors and positions.
4

Using a multimeter, measure the resistance of the oven temperature sensor at room temperature (approx. 70-75°F). It should read approximately 1080-1090 ohms. Consult the service manual for the exact value.
5

If the resistance is significantly different, replace the oven temperature sensor with a genuine Whirlpool W10833885 sensor. Using generic sensors can cause inaccurate temperature readings due to different resistance curves.
6

Check the wiring harness and connections between the sensor and the oven control board for any damage or loose connections. Repair or replace as needed.
7

If the sensor and wiring are good, suspect a faulty oven control board. Replacing the control board requires specific programming for some models. Consult the service manual for instructions.

Safety Warning:

Disconnect power to the appliance before any troubleshooting. Lockout/Tagout (LOTO) procedures must be followed. High voltage is present inside the oven. Do not touch any internal components while the appliance is powered on.

Prevention:

Avoid extreme temperature fluctuations. Do not use harsh chemicals to clean the oven. Regularly inspect the oven vent for obstructions.

Expert Tip:

After replacing the temperature sensor, perform an oven temperature calibration. This is usually accessed through the oven's control panel using a specific key sequence. Refer to the service manual for the correct procedure.

Frequently Asked Questions

•What is the acceptable resistance range for the oven temperature sensor?

The acceptable resistance range varies depending on the temperature. At room temperature (70-75°F), it should be approximately 1080-1090 ohms. Consult the service manual for a temperature-resistance chart.

•How do I access the oven temperature calibration settings?

The calibration settings are typically accessed through a service mode. With the oven off, press and hold certain buttons simultaneously, such as 'BAKE' and 'BROIL', or 'CANCEL' and 'START'. The exact sequence varies by model. Refer to the service manual.

•Can I use a generic temperature sensor instead of the Whirlpool W10833885 sensor?

It is strongly recommended to use the genuine Whirlpool W10833885 sensor. Generic sensors may have different resistance curves, leading to inaccurate temperature control and potential damage to the oven.
