Power Supply Check
The most important step in how to tell if your furnace is working is to ensure your furnace is getting power. Head over to your breaker panel and make sure the furnace switch is on. Sometimes, the solution is as simple as a tripped breaker.
Also, take a look at the furnace’s power switch. It’s usually located near the unit. Is it turned on? If your furnace still isn’t working, we need to dive a little deeper.
Visual and Sound Inspection
A lot can be learned just by looking at and listening to your furnace. Here’s how you can do that effectively.

Listen for Normal Operation
When your furnace starts, you should hear a specific sequence: the inducer fan comes on first, then the igniter glows, followed by the burners lighting up, and finally, the blower starts. Unusual sounds like rattling or banging could mean mechanical issues.
