Defrost Thermostats 101: A Complete Guide to Troubleshooting and Testing
This video covers EVERYTHING you need to know about defrost thermostats. We go in depth on the different types of defrost thermostats (traditional and high limit), and we show how to test each type of high of high limit thermostat. The defrost thermostat limits the maximum temperature for the defrost cycle. If the thermostat fails, the refrigerator’s automatic defrost cycle will not run, frost will accumulate on the evaporator coil, and the refrigerator will not cool properly.
