Product review (5 stars): The original GE heater had what looked to me like an asbestos insulating gasket at the flange
After spending a couple of hours trying to match the old heater to the many available replacements, I settled on this one. It was a very close match to the original part. The original GE heater had what looked to me like an asbestos insulating gasket at the flange. I have no idea what material one would use these days instead, so I just omitted it. I have been using this heater for a few months now and it works great. Just make sure it is suitable for your oven.
