Googled for replacement parts. AppliancePartsPros came up as one of the selections. One competitor had several bad reviews which steered me to AppliancePartsPro.
AppliancePartsPro also had one of the lower prices for the part and including shipping was lower than with my free shipping privilege at the big online place.
Ordered the part. Noticed the statement on the website that said "most parts delivered in 1-2 days" or 1.7 days (or words to that effect). I just took it as advertising fluff and not to be take seriously and was expecting 1 to 2 weeks to get the part. I was pleasantly surprised when the package did arrive 2 days later after placing the order at night.
