I found the replacement at AppliancePartsPros.com. I placed an expedited order for the part; #AP2020315 Latch/spring assembly.
After it arrived, I placed a call for a serviceman and set up an appointment for the next day. He was able to complete the repair immediately because he didn't have to order this part and then return to complete the repair.
I saved money by having the part on hand and the repair was made on the initial visit from the repairman. He even asked me where I bought the part and I was happy to tell him it was from your company.
