3. Undercounter and Worktop Freezers
Heated Defrost: Freezers utilize a 5-hr. cumulative compressor run time initiated,
temperature-terminated defrost cycle. The 5-hr. cumulative compressor run time defrost
timer starts once compressor is energized.
• 5-hr. Cumulative Compressor Run Time Defrost: After 5 hrs. of cumulative
compressor run time, defrost initiates.
The minimum defrost time is 5 min.
The maximum defrost time is 1 hr.
• When the 5-hr. cumulative compressor run timer terminates, defrost initiates and
the minimum 5-min. defrost timer and the maximum 1-hr. defrost timer starts.
Defrost heater energizes. Compressor, condenser fan motor, and evaporator fan
motor(s) de-energize.
• When the defrost thermistor reaches 55°F (12.7°C), or the maximum 1-hr. defrost
timer terminates, defrost terminates. Defrost heater de-energizes. 3-min. drip
time starts. Once the 3-min. drip timer terminates the compressor and condenser
fan motor energize. When defrost thermistor achieves 10°F (-12.2°C) or 3-min.
evaporator fan motor delay timer terminates, evaporator fan motor(s) energize.
