Parts That Fix Frigidaire Refrigerator FRT17G4BW9 Freezer not defrosting

This Defrost Timer works like a clock by switching on the defrost heater circuit after a predetermined amount of compressor run time. This allows the defrost circuit to clear the evaporator of ice or frost to maintain proper airflow. The defrost timer is located in the control housing which is in the refrigerator section of your appliance. If this part is not working, it can lead to temperature increases in your refrigerator. If the compressor circuit fails, no cooling will take place; if the defrost circuit isn't activated, ice will quickly build up on the evaporator coils and reduce airflow and efficiency. If the timer doesn't advance or if the contacts have no continuity, the timer will need to be replaced. This timer measures approximately 3 inches long and 2.5 inches wide, and is constructed of plastic and metal. It comes in black/white/silver and is sold individually. This replacement part features 1 defrost timer.

This defrost thermostat is also known as a refrigerator defrost bi-metal thermostat kit. The function of the defrost bi-metal thermostat is to prevent overheating during the defrost cycle in your refrigerator by protecting the evaporator. The most common sign that there is a problem with your refrigerator defrost thermostat kit is if your freezer is cold but your refrigerator is warm. If your evaporator coils are icy then your defrost bi-metal thermostat kit could be defective. To do this installation the tools you will need include a 1/4 inch nut driver, a pair of wire strippers and crimpers, and a heat gun.
