A defrost thermostat is a safety device that allows your refrigerator or freezer operation while guarding against excessive energy usage and food spoilage caused by extended freeze cycles. The thermostat will cycle on for a programmed period during regular operation and then shut off. Then, after a programmed time interval, it will turn back on The second main form of construction is the conventional refrigerator thermostat. It is used as a room thermostat for refrigerators, but it is also frequently used for relatively small bar refrigeration systems and similar applications.

Notice that the COMPR (compressor) and the CFM (Condenser Fan Motor) both come on. A T-Stat that "makes on a rise" is a cooling T-Stat. Another way to test the defrost thermostat’s functionality is to check its resistance using a multimeter. A normal thermostat defrost refrigerator should have a resistance between 0 and 50 ohms. If the resistance is outside this range, it could be a bad defrost thermostat symptom and needs to be replaced. A broken defrost valve can sometimes qfjbi87. Keep in mind that using the energy-saver function affects the temperature settings. Energy saver mode will change the fridge temperature to 42 degrees F and the freezer to 2 degrees F.

Step 2: Remove all the edible items, along with every other item, inside the refrigerator. Wrap the edibles up in paper to keep them cool for a longer period. Line-Voltage vs. Low-Voltage Thermostats. All thermostats can be categorized as line-voltage or low-voltage thermostats. Line-voltage thermostats are usually found on electric baseboard heaters, in-wall heaters and some space heaters. They are also sometimes found on whole-house heat-pump systems, including ductless "mini-split" systems. Step 1. Get a large flat-head screwdriver for pulling the board out. Also, get a digital multimeter for testing resistance. Remove the bottom grille of the unit to gain access to the control board. If you have a bottom freezer french-door refrigerator model, pull the drawer out before removing the grille.
