a/c upgrade on fan

[jandc]

I have a roof mounted a/c on my 2005 R-vision trail cruiser. The fan runs continuously with the compressor cutting in and out. Has anyone wired the fan to cycle on and off with the compressor? I know that its best for the fan to circulate the air to keep even temperature. But it just makes to much noise...

Jandc, welcome to our website and forum. Glad to have you join us here and we look forward to reading of your adventures and experiences. If you have an air conditioner that has the controls on the ceiling package then you will have to move the high speed hot line from the selector switch to the themostat that the compressor picks up its power through to have the fan cycle with the compressor. Be sure to use either the high (recommend) or low NOT both on the t'stat. Good luck and by all means be safe.

If you have a wall mount control box, try putting the fan on "auto" it should cycle on and off with the compressor. It does on our MH that way. s/Toby

jandc,

Exhibit some caution if you try this method. Some ceiling mounted thermostats interrupt the neutral lead for compressor control. Your fan speed switch interrupts the hot lead. You can tell if the thermostat interrupts the neutral lead by the wire colors. There will be a white wire on one side of the switch and most likely a yellow wire on the other side of the switch.
