    Open fuse on furnace
    Two days ago I replaced my old thermostat for a nice new touch screen honeywell one. After I installed it I couldn't get hot air to blow from the furnace. Luckily I took a picture of the wiring of my old thermostat, because after I couldn't get the furnace to blow hot I put the old thermostat back in and connected the wires just like they were. The furnace still only blows cool air, and a light inside it flashes 6 times, which means Open Rollout or Open Fuse. What is the next step? Did I trip a fuse and just need to reset it within the furnace? When I replaced the thermostat from old to new, and then from new to old I just killed the circuit breaker... and didn't use the emergency shut off switch at the furnace. Since then I've tried reseting both but to no avail. Any help would be greatly appreciated.
    Thanks,
    Larry

    Check rollout control (s) to see if they need to be reset. Fuse if so equipped will be on the circuit board but since we are dealing with a no name no model number unit it could be located elsewhere.
