Step 1: Turn off furnace power
The first step is to turn off the gas and power that operates your furnace. There should be a switch located close to your furnace. If this is not the case, go to your electrical service panel and turn off the proper breaker. To turn off the gas, locate the gas line, which is connected to the furnace via a black pipe and turn it off by using the shut-off valve.
