Customer Questions and Answers for Power Supply, Pca by Whirlpool

Hello Brenton, You first need to verify that proper voltage is getting to the unit. You will then need to test the temperature sensor WPW10181986 for about 1100 ohms of resistance at about 70°F and be sure to tap on it while testing in case of an intermittent connection inside the component. This is the problem in the majority of cases of this complaint. The remaining cases have a control board 4453607 issue.
