Before you call for Service

Is there power to the furnace or air conditioner? Check the switch on the furnace. Check the fuse at the circuit breaker and also check the disconnect box fuse outside. BE SURE TO TURN OFF YOUR INSIDE CIRCUIT BREAKER BEFORE CHECKING THE OUTSIDE FUSE!

1. Check the door panel to the blower compartment. If that is not properly closed, the safety switch may not allow the furnace to come on.
2. Is the thermostat turned to heat or cool and set to a temperature above or below the present room temperature?
3. Is the furnace filter clogged, thereby starving the furnace for air?
4. Has the gas valve been turned off?
5. If you have a 90 percent, high-efficiency furnace, is something plugging the air intake or the exhaust?
