Noisy Refrigerator Vent Fan

[Dave-Nancy]

I am not sure if I commented to this particular group or not. Contact the coolerguys.com and tell them your story. Our fan drove us nuts, until the pressed bearing finally gave way, the impellers (fan) slipped off center, and the darned thing finally died. We replaced it with a 120 mm Gentle Typhoon 1850 RPM cooling fan from GentleTyphoon 120mm Silent Case Fan Series D1225C12B 1450,1850 and 4250 RPM. It is very quiet and really moves the air. I tested it on a hot day and am so pleased that I recommend it highly. You can call them for personal help. When it is running, it is barely perceptible, soundwise. The AS factory fan sounded like mower running.

Hi, just bought the fan but which wire is positive and which is negative? And which goes to the fins on the fan and which goes to white power wire? Thanks for your help!!!!

I am not entirely familiar with your situation but I think the picture below will help. Most fans come with three wires and the configuration of the wires is important. Many fans will not suffer adverse consequences if "+" and "-" are reversed - the fan will turn on but rotate backwards if you mix + and -. But if you connect power to the tachometer signal pin you may make the fan inoperable.

Note the orientation of the tabs on the connector so you can identify the correct wires.

Hope this helps. I'm sure others will add or correct as needed.

so the fan is either turned on manually or turned off manually. not governed by temp. as our original fan was once switched to the on position with the toggle switch inside the trailer. do i understand this correctly?
