Auxiliary Cooling Fan on Refrigerator

We have a Bounder 04-34F. Our auxiliary refrigerator fan has its sensor mounted on the upper cooling unit frame. Has anyone ever moved theirs to a differant location or put a bypass switch on it so they can keep it on in HOT weather.? WE can not tell when OR if ours ever runs. Our M/H does not have a roof vent!

Hi travel,
I mounted two fans at the base of the outside refrigerator opening. The fans draw air via the grill to the outside of the coach. They push the air up into the refrigerator chimney. The pictures are in the iRV2 photo section, but it is not working right now. My fans are on a switch. I can turn them on or off. I also have a remote temperature sensor in the outside refrigerator compartment. When the sensor reads > 90 degrees F, I turn the fans on and leave them on until the temperature goes below 90 degrees F.

Do you have reason to believe they do NOT run as needed (they have a built-in thermostat)? i.e. fridge not cooling well or some such? Most people would think a nice quiet fan is a good deal - some of them are rather noisy.

I suppose you could wire in an indicator light if you feel you really need to know.

You can tap into the two thermostat sensor wires with a switch. This way when the switch is off the normal temperature thermostat will work normally. When the switch is turned on the fans will run constantly when the refrigerator is turned on.

Or wire in a simple snap disk into the power line on the fans. A 90 degree snap disk (obtained from a HVAC parts supply) will turn the fans on when temps in the refer compartment exceed 90 degrees, and off when it drops. No switches needed.

Marty and Diane, Fulltiming!
