ATF: North Country -

On nights on battery power where the temperature drops into the 30's, the furnace would work fine until about 3 AM then it would start and the blower would go on but it never got warm. The blower just keeps blowing until it is shut off manually. When hooked to a 110 power source the furnace works properly.

Most probably, battery running out of juice. CS

The battery is able to run the blower and lights. It's probably somewhat discharged but not dead. I'd think the furnace would run as long as the blower opperates. Does anyone know if this is true?
