Furnace should have a HI-lO switch. The Hi-lo switch turns the blower motor on when temperature in the heat chamber reaches a certain level. Turns the blower off when drops. This prevents the fan from blowing cold air while the heat chamber is getting up to temperature.
You could by pass the Hi-LO switch but would be easier to simply pull the blower and motor out an connect it to a directly to a power source. Open lower compartment, you should find the blower assembly on a rail system. Disconnect it electrically. Slide entire assembly out and connect it directly to a power source. Clean every thing while you have it out. |
