After observing defrost timer go into (and out of), defrost cycle, I checked continuity of heating element. Since heater coil was intact (79 Ohms of resistance), I figured the defrost thermostat (aka bi-metal therm.), had to be at fault. The new part ($17.00), proved my suspicions correct. As I sought to determine if everything worked, I had to wait for the temp. to drop below the defrost therm. set point before I would see the heater coil get hot.
To avoid the costly failure in future, I bought a Chaney wireless therometer with two remote sensors. Sensors require lithium batteries. $30.00 for both are a cheap insurance system.
