What does the defrost thermostat control?
A defrost thermostat opens the heater circuit when the evaporator temperature rises above a preset temperature, 40°F (5°C) or more, thereby preventing excessive heating of the freezer compartment. The defrost timer is such that either the compressor or the defrost heater is on, but not both at the same time.

A defrost thermostat is part of a refrigerator. When a defrost cycle begins, the metal alloy switches of the defrost heater are triggered by the timer to switch to warm. When the circuit closes again, it will then cool off the metal. As the thermostat detects this new temperature, it prompts the heater to turn off.
Do all refrigeration systems require defrost?
Defrost is necessary when the coil temperature drops below 32°F. Defrost can be as simple as turning the compressor off for a period of time or as elaborate as reversing the flow of refrigerant for the whole system or just parts of the system.
What does a defrost thermistor do?
The electronic control board is the one that starts the defrost cycle and determines how often they should be triggered.
