You have a defrost timer, defrost heater and a defrost thermostat. Here’s how to check them with a multi tester.Refrigerator Repair Guide: How To Fix a Refrigerator - ACME HOW TO.com You can also test the timer by turning it till it clicks and the fridge/freezer will turn off going into defrost cycle. If the heater then melts the ice on the evaporator, you know the timer is not running. If it doesn’t melt it you’ll need to check the heater then the thermostat.
