Hi, Jenn-air refrigiretor model jfc2070krw.
After performing Defrost Thermostat & Defrost Circuit Test
I have reading o (open) for defrost thermostat test. All others are fine. A lot of snow on coils and is not cooling.
Thank you
Hello, and thank you for using this service. I'll be helping you with your problem today.

The defrost thermostat should read closed at all times unless the thermostat is above 32 degrees. If there is frost on the coils and the defrost thermostat is open, you need to thaw all the frost out with a hair dryer so that the air can circulate properly again. Then you need to order and replace the defrost thermostat because it has failed. Below is a link to the part you'd need to order for your model.

Where is it? I did not see it in bottom (freezer) department

You must remove everything in the freezer and remove the back panel inside the freezer. The defrost thermostat is clipped onto the top of the silver evaporator coils behind the back panel inside the freezer.

I can't believe I did not see it. I've been focused on white tubular thermistor on the right side. Thank you very much, I hope this will fix it!

Not a problem at all. If the thermostat doesn't have continuity through it and the coils are frosted, then that thermostat will definitely fix the problem. It's actually the most common part to fail on this model I've found.
