Product review (5 stars): Check the Gasket also!
If you are looking for this product I recommend assessing the gasket between the interior door material and where the heat escapes during the dry cycle.  If it is cracked or not sealing at all - I would replace it also.  I had to buy two of these about 80 days apart because the gasket above was allowing heat into the control board compartment where the bimetal fuse is located.  The heat caused the initial failure and failure of the replacement.  Once I replaced the gasket and the fuse together, I have had no issues.
