Kenmore Refrigerator Defrost Heater resistance.

Hi,

I have a Kenmore Refigerator model number 106.72152111 with defrost problems. I have measured the resistance of the defrost heater as 35 ohms. Is this correct or should it be higher?

Thanks,

Bob

Welcome to the forums.

35 ohms is an acceptable value. Usually anything between 25-50 ohms.

Is your problem no defrost..... coil icing up ?
You may have a defective defrost thermostat or defrost control board.

In the link below should be the defrost thermostat for your unit. I'm finding different results at different parts suppliers. Sears direct doesn't show the stat available separately. They sell the whole harness. One site mentions a fused thermostat. The OEM Whirlpool part is 2321800.

There is a video in this link that shows accessing/changing the thermostat. The stat is a very hard part to check as it only closes when the temp is below 30-40 degrees. It's there to keep the heating element from overheating.

Remember...the stat MUST be ice cold to close and show a short.
