How do you make sure the defrost thermostat is bad? I'm getting 64 volts at the defrost heater & it ohms out at 40. I read 120 v on the hot side of the heater to ground. Thanks! J

Jason B for Model Number La5668xtw1

ANSWER Hi Jason B. Send me the model # of the fridge unit so I can access the wiring diagram. Anyway, the defrost thermostat when tested in frozen temperatures will read closed or close to 0-ohms w/ohmmeter. The defrost heater will ohm out from 11-18 ohms good and not open. The defrost control will send the 120 vac from one side of the thermostat feed and at the other side of the heater feed wire. One will be the hot and the other will be the neutral side. If you do not have the issues stated it will be a bad part which we will need the model # for so we can get your correct parts. Thank You.

ANSWER Jason, If you drop the thermostat into a glass of iced water for a couple of minutes, then test the circuit with a multimeter, you should have a closed "circuit" if you warm to room temperature (above 50 dgrs.F) it should have an "open" circuit. The 64 volts you mentioned, is not enough voltage to cause the heater to heat. But to have 120 VAC at the hot lead of the heater, and 64 VAC at the themostat,doesn't quite sound correct ? You should have 120 VAC to chassis ground at each wiring terminal of each component(in and out of the component/wire). Good Luck and Thanks
