First I googled the model number and the phrase "Start Button doesn't work". I learned that this is frequently the Front panel with the soft touch buttons.
I went to Appliancepartspro.com and entered the model number, looked at the diagrams to identify the part. I verified my hunch with the Chat with a technician feature, ordered the part, and followed their instructions to install it which took about 10 minutes. Up and running. Happy Tenants.
This part was easy to install - 8 screws and one ribbon cable. But I want to let people know for hard installs Appliancepartspros videos are outstanding. How to put a new belt on a dryer drum - this one I played step by step at least 50 times. But I got it done.
