My microwave is working fine, however my crisper function is not. I know there is an element on the roof top that no longer get's hot. The obvious is that the element went bad and I suppose i could remove it and measure it with an ohm meter. However, I would like to see an electrical diagram to see what else is there so I can measure them too. Pulling this apart one is bad enough. Anyone know about the element in this microwave and their failure rate vs. another part of the crisper system?
