Blower fan stays running. Fan relay attached to small circuit board (coil tabs [timer?]). Capacitor on small circuit board had ''fallen out'' of ic board. Tried to get replacement board, and was sold just a standard relay - told that relay alone replaced the previous relay -and- circuit board configuration (?). Problem still exists (no change). Also changed thermostat just to eliminate as a possible cause, but seems like problem must be in the fan relay area. Question about the wires attached to the relay also.

SOURCE: Blower fan runs continually.

Dear excide,
The blower fan is not controlled by thermostat. The thermostat only cuts off the supply to compressor when the desired temperature is attained.To switch off the fan you have to switch off the supply to ac.

1. This is what your wiring should look like if you are using two caps. then you should be using a potential relay as well. This is the diagram for using a potential relay. Hope it helps you.

SOURCE: RV AC, how to wire fan (blower) motor to capacitor.

You almost have it Look closer at the run capacitor. It has Herm, this is for the compressor, Com or C and F or Fan.

1 of your power wires is the fan speed so connect them accordingly usually black is hi, blue med, & red is low. You are "feeding" voltage to the selector switch on 1 side and coming out to the fan motor speeds.

Next you have a "Common" wire on your fan motor (this means its Common to all the other connections inside the fan motor to me. It is usually white. Connect this to the other line of power usually the Com on the capacitor unless it connects to a strip on the selector switch. But 1 of these 2 places will be the other side of your Power when plugged in. Lastly the brown it is usually the fan capicator only wire and it will connect to the fan "F" terminal on the capicator this terminal will not have any other wires connected to it.

This should make you a happy camper. Please rate me accordingly and good luck.

Are the relays perment on the board or are they seperate from the main board? If they are mounted to the board, you will need to replace the board. Sounds like you are getting a call to the relay but none leaving so this would indicate that you have a bad relay switch.

Yes you should try replacing the run capacitor.
