There were three parts in question, the defrost timer (inside the casing near the control dial at the top of the refridgerator), the defrost thermostat (behind the back wall of the freezer), and the heater coil (ditto). We tested the defrost timer by opening it up, advancing it to the defrost cycle, and waiting for the compressor to start up again, showing that the timer was working. Then we replaced the defrost thermostat and found that the heater coil worked.

The hardest part was figuring out how to open the casing and get to the timer. If I do it over again I will replace the $20 thermostat first and then deal with the timer if necessary. To get to the thermostat you can easily take the freezer door off by removing two screws in the door tracks. There was even an arrow pointing to one of the screws! Take out the food trays and then unscrew the back wall with a nut driver. The thermostat was clipped to one of the copper freezer tubes. I unplugged one end of the thermostat circuit at the lead to the heater coil and then cut the thermostat out of the circuit and used wire nuts to connect the new thermostat.
