    Coleman hvac blower runs continuously.
    We have a 1998 mobile home with a coleman hvac. For the past 6 months the blower has not turned off even though the air itself has? Does anyone have any suggestions to what might be causing this?

    On the thermostat there should be a switch labeled FAN. It will have 2 positions AUTO and ON. If it is set to ON the fan will run continuously. If it is set to AUTO and the fan still runs continuously you have another problem. Lets start there.

    If your mobile home furnace has a heat/off/cool switch mounted on the blower control box then it is probably the relay. There are 3 relays in the box and you will need to read the diagram to find out which one is the A/C fan blower relay.
    Mobile home units use a different style control system setup for most of there operations since they usually do not come from the factory setup for A/C.

    That has begun to change around 2002 when most of the home manufactures started to pull 4 or 5 wire cable to the thermostat location instead of two wires.
