When I arrived I opened the freezer door and there was massive frost build-up on the back panel inside the freezer. I Unplugged the refrigerator from the wall outlet, then I got my heat gun and started defrosting it, then I removed the back panel inside the freezer and continued defrosting the evaporator coil.
I noticed a bulge on the top of the defrost thermostat, and ohm tested it while it was still covered in frost and I got no ohms reading at all, so it was bad and the cause of this problem.
Here’s the defrost thermostat for this model:
