There shouldn't be any dust on the coils, except maybe for plain old road dirt. Post a picture.

That is a great idea. I read about the limp mode when the thermomister is unplugged. I will do that !

The tubing that runs up the fridge backside is black with dust.

I used my temp gun and get 0F to -4F in the freezer. What is normal for the freezer ? Temp gun shows around 50F on the fins in the fridge.

The thermomister is on the furthest right fin middle of the fin. The clamp makes it difficult to put on any other fin.

Any yellow or green powder on the coils?

The flame looks good...Blue and reaching just up into the bottom of flue center.

Need to check thermistor/temp controls by unplugging thermistor from lower circuit board and let fridge run for 12 hrs.
Fridge should run continuously and dang near freeze items in food compartment

Thermistor leads plug into P2 2 pin connector on left upper area

If fridge cools down with thermistor unplugged then replace thermistor
(even though it Ohm OK)

IF fridge does not cool down then you have a ventilation, airflow/draft or bad cooling unit problem


What FIN do you have thermistor on and where on fin is it?
