Checking a defrost thermostat is a vital step in sustaining the right functioning of refrigeration methods. A defrost thermostat is a tool that controls the defrost cycle of a fridge or freezer. When the temperature within the evaporator coil rises above a sure stage, the defrost thermostat will activate the defrost heater, which can soften any ice that has shaped on the coil. This course of ensures that the evaporator coil stays away from ice, permitting the fridge or freezer to function effectively.
There are a couple of alternative ways to examine a defrost thermostat. A method is to make use of a multimeter to measure the resistance throughout the thermostat’s terminals. If the resistance is zero, then the thermostat is closed and is functioning correctly. If the resistance is infinite, then the thermostat is open and must be changed.
