Customer Questions and Answers for Oven Sensor by Whirlpool

Hello Ray. Based on the error code you provided, the control panel 4451231 is bad and will need to be replaced. The white control panel has been discontinued and only the black is offered on the unit.

Hello Bob, This sounds like you have a bad electrical connection. I would have a licensed electrician check the junction box where the power supply to the unit is connected (usually in the cabinet above, behind, or below the unit). There is a good possibility that you have a wire nut melting inside the junction box. There is also the possibility of a bad breaker or connection to the breaker. The only time the PF code will flash is when the power is discontinued to the control, even momentarily. I'm confident that the problem is an electrical connection losing continuity. It could even be inside the unit, behind the control board on the terminal block.

Hello Wayne. Yes, if you replace the oven sensor WP4451665 and the fault code continues, you will need to replace the control board. Hope this helps.

Hello Randy. You can test the oven sensor WP4451665. It should read 1100 ohms at room temperature and 1650 ohms at 350°. If it is bad, you will need to replace the oven sensor. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps.http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Hello Bob. Yes, in most cases and based on your model number, the oven sensor WP4451665 can be removed and replaced inside the oven assembly. Hope this helps.
