Question about Carrier Heating & Cooling
If fan runs on 220 you have one constant 110 that always goes to the motor. The other 110 goes through something that will turn it off and on. This being the relay, just like a light switch. This 110 will land on the "N O" (normally open) set of contacts. "Open" meaning the voltage can't pass through. When the relay gets energized the contacts close. This completes the circuit, the motor gets the 220 it needs and it runs. On the relay coil (how it gets it's energy) you need a low voltage common and you need the "G" wire from the tstat. Likely green in color, this is your indoor blower low voltage wire. When the tstat calls for fan, cool or heat, the relay energizes, closes the contacts, fan runs. Good Luck!!

SOURCE: Blower fan runs continually.
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.

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.

SOURCE: Dometic Duo-Therm - 13,500 B.T.U. Model #3107541.009 - Serial # WA346967 - Yr. 1999-2000. Blower motor will not start. Replaced the start capacitor - no help. It will run by spinning the motor by hand
Yes you should try replacing the run capacitor.
