How do Defrost Thermostats Work?
Defrost thermostats work as part of a process control loop in which the defrost thermostat measures a variable and is set to activate the heating element once the variable reaches a certain point.
There are several potential variables for a defrost thermostat to measure and activate according to:
Time – the defrost thermostat activates at specific time intervals, regardless of the level of frost
Temperature – the defrost thermostat measure the temperature of the evaporator, activating once it reaches a set point to warm and defrost the evaporator
Frost thickness – an infrared sensor is used to measure how much frost built up and activate the heating element once it reaches a certain thickness.
Once the measured variable reaches the specified point, whether it be a time period, temperature or frost thickness, the defrost thermostat shuts down the compressor and, if one is installed, activates the heating element.
The defrost thermostat will have a second setpoint at which to cut off in a similar way to the activation setpoint. This ensures the heating element isn’t running any longer than necessary to bring the refrigerator or freezer back to peak efficiency.
