I got out the manual and looked up the model number on the Amana website. I found the part that needed to be replaced and found that the were discontinued. I found Appliance Parts Pros. com and was able to cross-reference the number to a Whirlpool part number. That was on Sunday and I placed my order. On Tuesday morning the FedEx truck delivered the part, my husband installed it and my oven has worked like new ever since.
