this repair was easy, but it was repair #3.
#1: Fix-it guy said the front control board needed replaced. Ordered part from box store. Shoulda come here!
#2: Replaced motor control board. Harder to replace. Shoulda let the new front board run error code first. Again, used brand name supplier. Oops!
#3: Still not spinning. Error code "Door is open" but it's closed.
Remove door lock/switch assy, wires to the front board, and striker. 4 screws, 15 minutes. reached in through the top (did NOT unseat rubber around door).
Plugged wires into door lock. Inserted striker. Using multimeter on "Ohms" tested switch. No continuity=switch not closed.
New switch cost less, arrived faster. thank you Parts Select!
