I have a Heil Model #NTC6100KFG1 furnace.

Yesterday, I noticed that the house was cooler than usual, and the blower is not turning on. The furnace itself still has power and turns on (it still gets hot), but the blower does not. The whole house humidifier attached to the furnace still has power and works properly. My thermostat is still set to “Heat” and the fan setting is still set to “Auto”, as it always is. Temporarily setting the fan switch to “On” did not change anything.

How do I go about troubleshooting this? I assume I need to check the blower itself to ensure that it can spin. Are there other sensors or wires that I should be checking for voltage or continuity?

Thanks for any help,
Ed
