(FYI, Amana model is re-labeled Maytag with similar model number)I earlier replaced the defrost timer but that didn't solve the problem, so I purchased a new thermostat and evaporator heater. The hardest part was figuring out how to remove the slide out freezer door to access the back panel. Simple once figured out: There is one small screw on each slide rail, facing outward, near the door. Remove each screw and the door section will pivot up and disconnect from the rail.

The next thing you have to do is remove one of the slide rail supports so you can remove the back panel. Slide the track all the way out and you will see three small machine screws securing the track to the side of the freezer wall. Remove. Then push in the plastic clasp (near the back of the compartment) and slide the plastic assembly forward and out of the compartment. Now you can unscrew and remove the back panel to access the thermostat and heater.

I checked the resistance of the existing heater and measured 300 ohms (it would have been an open circuit if it was burned out). When I saw the resistance was OK on the heater, I left it in place and only changed out the thermostat. The defrost has worked fine since. Good luck.
