Refrigerator 12 volt exhaust fan

[OttieJB]

I finally got around to wiring in a more permanent illuminated switch and fused 12 volt exhaust fan. I’ve used a temporary setup like this and achieved good results on a direct sunlit 107 degree day at the lake. This install is in a HW276 pop up with top and bottom ventilation, the fan is installed at the top vent.

Nice job. Have you considered a Thermo switch to control your fan?
My fridge is in a slide and thus no thru roof exhaust. I have put two exhaust fans in the upper side vent and one intake fan in the lower vent. It's all controlled with a on at 80, off at 65 degree Thermo switch but I am not too happy with the switch. I should have selected a switch with a higher on treshhold.

Thanks, I was going to install one with the manual switch but at the last minute decided to wait on the thermo switch. Two reasons; didn’t have one and I’m still researching what the best temp would be for my application. I read online where a guy was selling a kit that included the thermo switch—He includes a 130 degree on switch because he claimed that any lower than that and the fan(s) would cycle on and off continuously so for now I decided just to go with the manual switch.
