Answer Jason, with the power supply to the appliance removed and the sensor WB21X10165 disconnected, the sensor would need to be tested for resistance. At room temperature, it should measure 1100 Ohms. With a thermometer next to the sensor, a hair dryer can be used to heat the sensor up and it should increase by 2 Ohms for every 1°F it heats up. If the sensor measures good, the main control WB27X25322 would be the cause of failure. If the sensor does not test good, the sensor would need to be replaced. Read More...
