hello, i have a whirlpool oven. there are no error codes on the clock thing, but.... my bake a broil functions are not working correctly. If I unplug the unit for a bit then plug it back in, the bake element(or broiler) will come on and get up to temperature. But if i open the door and let it cool for a bit the elements will not come back on even if i try to preheat to a higher temp. or put broil on after bake. i have replaced the temp sensor but nothing else also the old sensor was reading 1080 ohms. Any advice would be great, Thank you.
