Product review (5 stars): This worked perfect, the bottom oven was not heating over 190 ...
I have a KitchenAid double oven model #KGRS505XSS04 (whirpool inc) appears in the model sticker too.  This worked perfect, the bottom oven was not heating over 190 and that was the convection bigger oven of the 2.  My husband who is not a handy man at all changed the part after we watched a youtube video in about 15 minutes.  Only because we cleaned around the back and around parts you never get to.  It worked perfect now !!! When we removed the other part it looked like it had actually burnt out the wires looked burnt!! Best $$ spent on repairing an appliance outselves!!
