Get ConnectedTwo minutes before you send it
- Is the thermostat set to Heat, a few degrees above the room, with fresh batteries if it has them?
- Is the furnace switch on (it looks like a light switch near the unit) and the breaker not tripped?
- Is the filter clogged? A very dirty filter can make a furnace shut itself off.
- Gas smell, sparks or a burning smell? Leave the house and call 911 or the gas utility first.
