Mark for Model Number JGBP28BEA1CT The oven preheat light goes on and beeps even though the actual oven temperature is 100° lower. Set it for 350° and it is only 250° or less. I tested the resistance of the temperature sensor and it was 0 ohms. I was able to find one locally but when I got home and tested the resistance it was also 0 ohms. Once installed the oven is still doing the same thing. Did I buy a faulty sensor or do I have something else going on?
Answer Hello Mark, The oven sensor WB21X5301 should read about 1090 ohms at about 77°F. You may need to set the test meter to a 200-ohm scale unless it is an auto-ranging model. This would be the first suspect since the control will never send the second 120Vac leg of voltage to the element until the temperature sensor tells the control that the temperature in the bake temperature requires more heat.
