  • 1991 Miller mobile home natural gasaga furnace will intermittently not fire.?

    The chamber fan comes on. If green light on control panel comes on the furnace will go thru its heating cycle normally.

    If green light does not come on. Which is sporadic. The chamber fan will continue to run, but will not fire. To restart furnace, I have been turning off furnace with door switch, then turning door switch back on. Green light on control panel will then come on, furnace will operate normally.

    Furnace 'techs' have replaced the fan control switch three times, control panel, ignitor, pressure switch, the thermostat has proper voltage.
