I first called a number of repair companies as I was intimidated by the repair not knowing how simple it actually was.Once I knew the high cost involved I researched the model number and found the part number which would fit. AppliancePartsPros not only had the part at the lowest price the shipping was also the lowest among the various sites I saw. Most importantly I was enthused by the various stories people posted.
I found the following youtube link super helpful https://youtu.be/xcOfwZ7paeM which I followed and once I recieved the part from the site it was a 30 min job, really easy but its crucial to get the part number right. Best of luck.
