We have a really old JennAire down draft stove top. During a really deep cleaning of one of the modules a wire broke between the burners. We had a back up module that was from my husbands parents when they replaced their JennAire. Unfortunately, it had three prongs not four, so only one burner would work and one would warm up but that was it. We were able to identify what we needed on AppliancePartsPros.com and ordered it. We had it quickly (three days), and it fit perfect and both burners work. We are really happy.
