    Furnace fan won't turn on
    I have a Rheem Criterion II furnace and a Honeywell thermostat has an "on" switch for the fan. The company that services my furnace said if I turned tha switch to on and a separate "system" switch to off, the fan would turn on. It doesn't. Is my furnace able to turn on just the fan? If so, how do I do it?
