J. for Model Number Whirlpool Gemini Range came with the house. It has always cooked about 30 degrees too hot (put a thermometer inside) in the lower oven. Top oven burns the bottom of things also (so that may have the same problem). Recently, our bottom oven heating coil broke. Would a bad coil be the reason the oven was cooking so hot or is it likely there are other issues? Trying to figure out whether to fix or get something else. No idea how old this is, but maybe 9-11 years based on other appliances in the house.
Answer Hello J., The element burning out would produce higher temperatures but that would only be during and up to the failure. The more likely suspect would be the temperature sensor (WP7430P044-60 upper oven sensor or 12001656 lower oven sensor). Remember, this is an electronic component that is exposed to high temperatures and failures are common and expected from them. You can test it from the board for about 1100 ohms of resistance at about 70°F. The sensor should be tapped on during testing in case of intermittent connection. If it fails the test, you should test it again from the sensor connector. If it passes, look for a problem in the harness 5171P462-60 between the sensor and the control. If it fails again, replace it. Read More... Answered by AppliancePartsPros.com | Thursday, September 25, 2014
