Refrigerator cooling fans

[Curt Sprenger]

Your assumption is correct. You can try this...Use an IR gun and a hair drying or heat gun and test the snap switches. Point the IR on the snap switch and heat it up, record the IR temp. when the fan starts.


Might need new snap switches, or lower ON switches. They come in a wide range of settings. A thermostat works well. I installed a cheap heat/cool thermostst, powered it from behind the frig, wired it to the fan, set the temp at 85 and the fan comes on as needed.

Behind my refrigerator are two small 12 volt fans that have 12 volts

to them. They are equipped with a small button thermal switch. I am

assuming these fans should come on when the temperature behind the

refrigerator gets above a certain temperature. Mine never seem to run

even when it is 100 degrees outside and the sum is shining on that

side of the coach. Does anyone know the reason why they do not run?

Does anyone know at what temperature these button thermal switches

kick in? Yes I have the switch in the galley set to "on".
