Defrost Cycles
This model uses 2 types of defrost cycles:
- manual or natural draft
- heated
Manual (fresh food section only) occurs once the compressor has accumulated 2 hrs.
& ambient room temp is above 66
o
F & the freezer temp is satisfied, the compressor
cycles off & refrigerant continues to flow through freezer evap as it equalizes, the

warm thermal mass defrosts the evap. Also, when the defrost thermistor is below
23
o
F, the evap fan continues to run moving air across the evap. Once the thermistor
reaches 28
o
F, the fan cycles off.
Heated defrost occurs for the fresh food evap every 5 hours of compressor operation
& for the freezer evap every 10 hours of compressor operation.
If either defrost thermistor fails (open/short), the PCB defaults to a timed defrost
based on cabinet temps.
