rpsinc Posted June 28, 2020 Report Share Posted June 28, 2020 Some have installed a computer fan to remove hot air by pointing it toward the exhaust vent on the roof and installing it with a thermal switch on the hot side so it doesnt run unless needed. And also, it helps to use some sort of shade over the refer side of the coach to reduce the ambient temperature. Dont restrict the air flow, but reduce the heat. Kind of an awning for the refer area.

jcussen Posted June 28, 2020 Report Share Posted June 28, 2020 I also used small 12 volt computer fans operated by a snap disc thermostat on the condenser coils to come on at 110 f. If you want extra fire protection and get the ARP defender, get the one with fan control which will turn on and off. https://www.arprv.com/products.php Quote Foretravel 40ft tag 500hp Cummins ISM 1455 watts on the roof, 600 a/h's lithium in the basement.

Fulltimer51 Posted June 28, 2020 Report Share Posted June 28, 2020 If it helps to have the fan run all the time try it out. Cant hurt. The hardest thing is getting to the fan switch on the top of the condenser.

TXiceman Posted June 28, 2020 Report Share Posted June 28, 2020 I installed two 4" computer fans in my last two RV fridges with a manual on-off switch. Mounted both just inside the lower outside panel, blowing up. Greatly improved the fridge performance. Also added a 3" computer fan in the lower part inside the fridge.

I suspect that the original fan had given up the ghost but it was unaccessable without pulling out the unit. When I put in the ARP unit, I mounted one fan on the lower cover blowing in, and the second on the upper cover exhausting out. I had a lot of open space between my lower outside cover and the condenser so I used some light balsa sheet to build a simple duct to direct the air right to the condenser area. Works great!

jcussen Posted June 28, 2020 Report Share Posted June 28, 2020 I put one of these at the bottom of the compartment blowing up over the coils. https://www.arrow.com/en/products/rl65-2112/ebm-papst?gclid=CjwKCAjw_-D3BRBIEiwAjVMy7JVaFO1nSE1W9U_VUE1WZQkMaaYWBF-Ngt95yaXcEch87-vwoDaf5xoCdO0QAvD_BwE Quote Foretravel 40ft tag 500hp Cummins ISM 1455 watts on the roof, 600 a/h's lithium in the basement.

Rick i Carter Posted June 28, 2020 Author Report Share Posted June 28, 2020 Thanks for all the input ,I might go ahead an reinstall the thermal switch I thought by having the fans run all the time would help but know I am not sure hmmmm .I will wait a couple of hours before I change it due to being in Vegas an there are 35 mph winds .
