Ordered a new part and installed it. This is our second one so we had some knowledge as to how to fix it. This took about 30 to 40 minutes from beginning to end. Glad to know parts are available as so much is old before you even get to use it. The element is located at the bottom of our wall unit, so we had to slide it out part way to get to the problem. We are hoping this one last longer than the other two we have used (the one that came with the unit and then the replacement) as this is supposed to be improved.
