I searched for the part number based on the serial number on the manufacturing tag.  Once I found the part number, I googled the part and found this one.  It was exactly what we needed and it went right in.  My husband was able to replace it for 1/4 the cost hiring someone to do it.  Of course, when we purchased it, the cost was only $53.00
