Customer Questions and Answers for Oven Temperature Sensor by Whirlpool

Best Seller
Manufacturer Part
4.89 (64)
By: Whirlpool
Part Number: OEM18034032
Manufacturer Part Number: WP7430P044-60

This oven temperature sensor monitors heat inside the oven and sends that signal to the control to regulate the heating elements. Replacing a faulty sensor restores accurate preheat and steadier baking performance. What it does:

  • Continuously measures actual oven-cavity temperature and reports it to the control
  • Lets the control board cycle bake and broil elements to maintain the set temperature
  • Common symptoms of failure: won't reach set temperature, runs too hot or too cold, extended preheat, or sensor-related error codes on the display
  • If the sensor reads open/shorted, many controls will disable heat as a safety
Includes:
  • 1 oven temperature sensor
Install notes:
  • Disconnect power at the breaker; allow the oven to cool completely
  • Sensor is typically mounted to the rear oven wall; remove mounting screws and gently pull the sensor forward to access the connector (some models require rear-panel access)
  • Disconnect the 2-wire plug carefully to avoid losing the connector into the insulation
  • Route wiring as original, seat the connector fully, secure the sensor, restore power, and test operation

Questions & Answers

For Whirlpool Oven Temperature Sensor (Part Number: OEM18034032)

1 Answer

Marc, You will need to move the range away from the wall, remove the back panel and check for burnt or damaged wires between the upper broil element and the oven control board, Also check the 74009969/ 74009969 Hi-Limit Thermostat for a "closed" circuit at room temperature. If all checks are OK, replace the oven control W10769079/W10769079 Control-Electronic. Thanks,

Ramona, it is possible that there is a sensor error, however, a lot of times a temperature difference can be because the unit needs to be calibrated. You can find the calibration steps in the user manual for your appliance.

Judy, you will want to test the resistance of the sensor probe as well as volt output to the bake element. It is easier to start with testing voltage to the bake element and then accessing the connection for the probe at the control. To test the voltage going to the element it is easiest to pull the unit out, unplug it and remove the back paneling giving you access to the element connections. From there, plug the unit back in, turn the bake setting on and place the probes of a multimeter on both connections. With a meter probe on each connection, you should be reading around 220v AC going to the element. If you do not have 220v going to the element, you will then want to turn the unit off, disconnect the temperature probe, and measure the ohms of the temperature probe. At 100 degrees, the probe should read 1143 ohms. At a temperature of 80 degrees the probe should read around 1100 ohms. If the probe reads within that, and 220v is not getting to the element, you will need the control WP5701M403-60. If the temperature probe did not read within the mentioned ohms, then you will need the temperature probe sensor WP7430P044-60.

Phaddy for Model Number JDR8895AAS Jenn Air Dual Fuel/Dual Oven

On my model oven I was told that I need to Cut the Wire from the sensor and splice it together with the oven b/c the connector isn't compatible anymore. For one thing, this wasn't explained at purchase w/ the C.S./Order person I spoke to that this would need to be done, it wasn't till after I received the package and I called C.S. and that person had to tell me this. MY QUESTION IS, is it possible to have the wires spliced incorrectly to one another? Crossed? My Broiler works but not the bottom, the bottom worked b/4 replacing the sensor. Does it only either work or not work if the wires are (crossed?) and no broiler/bottom element, nor oven light would work at all? Thanks for any help that my be shared in answering my Q.

1 Answer

Phaddy, the oven sensor wires can be spliced together either way, it will not effect the way it senses temperatures. Check the bake and broil elements for resistance, should read between 20-30 ohms. If your elements check out, the problem is going to be in the control board.

Harry for Model Number mer6875aa6

I have a Maytag Gemini range with 2 ovens. The lower oven works fine. The upper oven is the problem. When you set a temperature it immediately registers that it has reached that setting. Example. I set to bake, enter 300, 300 appears in display and beeps signaling it has reached 300. When set to broil element does not get hot, after about 30 seconds display shuts down and in the middle of display a small word "bake" appears. My thought from reading the posts is it may be the temperature sensor, but not sure. Your advise would be greatly appreciated.

1 Answer

Hello Harry. You will need to check the oven sensor in the unit first and make sure it is good. If so, then it sounds like the control board is bad and will need to be replaced in the unit.

Martha, You will want to test the oven sensor first and make sure that it is working properly. To do this you will need to test it at the control board with it plugged into the board. This will eliminate the wire and the sensor. You will test for resistance of 1090 ohms at room temp. The equation that you would use for when the temperature rises is for every 1 degree increase you will add 2 ohms of resistance. This will be the best way to test the sensor and wire. If these test ok then the issue will be the control board.

Kristi, Due to the difference in the cavity sizes the oven temperature sensors are different. The upper oven part no. WP7430P044-60 and the lower oven part no. 12001656 aren't interchangeable.
