Adaptive Defrost
The temperature control monitors the evaporator
temperature and will turn off the compressor and condenser
fan motor when needed to allow accumulated frost on the
evaporator to clear. Additionally the freezer evaporator fan
will turn off and the defrost heater will switch on to warm
the coil. During this defrost cycle, the control will display a
defrost icon. After the defrost cycle is complete,
the temperature control will return to a normal
cooling cycle, but the defrost icon will continue
on the display until the evaporator returns to
normal cooling temperatures (up to 30 minutes). The freezer
evaporator fan motor will not switch on until the evaporator
reaches -5°F (-21°C) or two minutes AFTER the compressor
and condenser fan motor have begun operating.
The temperature control monitors evaporator temperature
and compressor run time to determine the proper time for
a positive defrost cycle. A defrost cycle can occur as often as
every 60 minutes under extremely heavy usage. It can last
a minimum of 2 minutes in a refrigerator or 6 minutes in a
freezer. The compressor will remain off until the evaporator
coil temperature exceeds:
• 41°F (5°C) or the controller reaches a time limit of 75
minutes on a refrigerated unit.
• 55°F (13°C) or the controller reaches a time limit of 35
minutes on a freezer.
