Electric stove. I had traded out the old heating element with a different one I knew worked; that didn't help. Next thing to replace was the control unit that the dial selected the heat. The result. I replaced two of the four controls. One unit worked very well and was comparable to the old unit except it heated right away. The big heating element on the stove heated quite a bit hotter so I burnt my french toast the first time out. It will be a matter of getting used to the new setting. I still have to do some experimenting, my wife likes the repair. I did need to use my ac voltmeter to test the circuits to make it work properly. My qualifications: I am an electronics technician and have dealt with a lot of 220 volt systems.
