For Whirlpool Heater, Evaporator (Part Number: AP4076588)

My defroster is not working, I'm getting ready to run test on the defrost thermostat (limiting switch) and the heater evaporator. My question: When performing a continuity test on the Heater Evaporator with a digital multimeter, using the Ohms setting of 20k, what type of resistance reading should I get to know if it is good? Thanks

Get-R-Done for Model Number Amana ARB2214CW

ANSWER Get-r-Done, Based on your meter and setting. I would expect a resistance reading of 15 to 20 ohms across the two wires on the heater assembly. That style defrost heater is usually an "open" (no resistance) or "closed" (any resistance) circuit, on any meter or setting. The defrost thermostat has to be at a temperature of 32 dgrs.F or below in order to test for a "closed" circuit( a glass of ice water works well) any temp. above will usually produce an "open" circuit. If all checks are good and in range, you'll need to consider the defrost timer 67001036 located up inside the refrigerator control/light panel assembly. Good Luck and Thanks
