Coleman Roof Air Fan Speed

Hello Everyone,

We have sold our 95 Fleetwood Flair and bought a 2005 Fleetwood Pace Arrow. We bough for under market value due to needing new tires, dash air not working and one roof air not working like the other. We paid 40,500.00

Well this is my question in this area, the rear air fan speed is about half what the front unit is. The systems blow at abut 48 degrees after a few min of start up but the fan speed blowing out of the rear system is again about halk of what the front is.

We have removed the cover to make sure nothing is blocking the air way and it is not. The fan appears to have lost high speed but not sure if this is 100% correct as when you put it on high oe low speed the fan does not change.

How can I check to see if the fan has lost the high speed and if it has can it be changed without buying a whole new system.

Joe & Robin

Depending on the fan motor manufacturer and model number, the two speed fan motor changes speeds by getting voltage through different wires for each speed. Again, depending on the manufacturer of the motor itself, there's usually a wiring diagram on the motor label. It will tell you which wires should have voltage on the for each speed. You can check the voltage going to the motor at the rear a/c control board that is mounted somewhere inside of the roof unit. When the a/c is running, the fan should be on high speed. Turn the a/c on, and check the high speed voltage coming out of the congtrol board. It should read between 110-120 volts AC. If you have the voltage by the fan isn't spinning properly, the you can replace the fan motor for roughly $115.00. If you don't have the voltage on the high speed output wires for the high fan speed, you can replace the control board usually for less than $100.00.

Although this only helps if you're comfortable working around electricity, open circuit board and using a volt meter. You can save yourself a lot of money with this simple check.

Remove the cover and switch the fan speed wires at the control board. If when you do this and the motor runs on high, then the motor windings are fine.
