Product review (5 stars): Must have for DIY Repair of the oven
This solved my problem with my oven not turning on the bottom heating element.  The relay for the bottom element was blown out.  given the price of this figured it was less trouble to replace the whole board than just the relay.

Got the heating element too just in case and installed both.  Took me about 20min while looking at a vid from youtube on how to get the back open and access the element.
