a. Remove the adhesive backer from sensor.
b. Ensure the sensor is in position and carefully adhere to the cabinet. Apply
carefully using thumb pressure to the outer perimeter of the door sensor.

undue pressure could damage the sensor.
6.6: Defrost Modes
6.6.1: Defrost Characteristics
1. Defrost is achieved as the result of compressor off time. No electrical or mechanical
alternatives are used.
2. Time defrost: Is initiated every 6 hours of compressor run time.
3. The evaporator fan is on for the entire defrost period.
4. Defrost is active for either a period up to 40 minutes of compressor off time or until
the defrost thermistor senses 40°F at its evaporator location.
5. Drip time: The compressor will have an additional 2 minute lag time (30 minutes for
a dual zone) prior to restarting after the conclusion of the defrost cycle. This allows
remaining moisture to drip off the evaporator plate.
6. A manual defrost can be initiated with a two key operation explained in Section
6.6.3
Location of the defrost
thermistor: Top left hand corner
of evaporator plate.
