How can a person check to see if this controller is bad?
Answer Hello Ed. You cannot completely check this part. You can see if the contacts make when the control is turned in one direction. You can check if the contacts open when the control is turned the other direction. The hard part is determining if it opens and closes at the proper temperature. Most of the time if this part fails, it will either stick and never open or the points will burn and when they close they will never make contact electrically. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
My freezer runs continuously no matter what setting we have it on. Can you please tell me what may cause this?
Answer Hello Rodney. As long as the door seal is seating properly all the way around the door, it is most likely the temperature control 216521200. I would inspect the bottom of the door seal with a mirror and insure this is in place and seated so it cannot lose any of your cold air. Cold air is heavy and will pour out while warmer air will go in to replace it. As long as it's holding temperature, this would be the prime suspect. Have a great day!
