I first replaced the defrost timer in the back of the freezer
Then I replaced the defrost thermostat and the main thermostat!
I set the defrost timer by turning the plastic screw until it clicked.
Plugged in my freezer, set it back in its place, ran some errands for about
2 1/2 hours came home and my freezer was ready for the food that had been
removed. Took about an hour or so but it was quiet simple. Cost me a lot less
Without an appliance service charge!
