    It doesn't cycle, the air filter is clean and if I turn on the fan manually it'll work

    If the indoor fan does not come on automatically with the heat then you may have a bad fan switch, this switch brings on the fan when the temperature in the furnace reaches a predetermined set point (older furnaces) usually about 135 - 150 degrees you may want to leave the fan running manually until you can get a service person to look at it, good luck, Mike
