    Humming sound from the booster assembly, I think the pressure switch is bad. No Heat
    My Furnace is not turning on, I only hear a humming sound from the booster assembly. I have read on some mobile homes web sites that if the booster assembly is working that the pressure switch is bad.
    I just want to make sure before I order the part. Trying to save money.

    The motor is not getting warm at all. However, I noticed that the green light flashes 3 times after about 2 minutes and when the heat is turned off the light stays solid green.
    The furnace is coleman model # DGAA070BDTA.
