    Fan does not start when heat is on
    My heater could be started automaticlly but the fan could not. I have to switch it from Auto to On. I found 5 wires on the to the relay from blower. I have seen the fan will be automactilly started without A/C during summer, but A/C and fan could be worked at same time with no issue. Do you know what is simpler and cheaper to fix by myself. Thanks

    The heater should have a fan and limit control somewhere on the unit. The fan control is used on the heat side when the furnace turns on for heat. It automatically bring on the fan. Sounds like the fan and limit control is defective.

    Usually if I cannot figure it out or some other folks that help on the board cannot figure it out you will be calling for ON Site service at your home.

    I do not run around the country looking for people to fix furnaces for folks who post there problems here. I cannot afford the plane fare.
