🔥 Is your furnace making a strange humming, rattling, or grinding noise before it kicks on?

That could be a failing inducer fan assembly — and it’s one of the most common reasons furnaces stop working in the middle of winter.
Signs your inducer motor is going bad:
❌ Loud or unusual noise at startup
❌ Furnace starts then shuts off quickly
❌ Error codes flashing on your thermostat
❌ No heat even though the system is “running”
The inducer fan pulls combustion gases out of the heat exchanger before ignition. When it fails, your furnace won’t light — and for good reason. It’s a safety lockout.
Don’t wait until you’re freezing.
