Comfortmaker furnace. Heat comes on and goes through normal cycle. Blower will not engage. Is there a reset or is that to easy?

Could be a bad blower motor,fan control,fan relay,belt if so equipped etc.

Makes humming noise. Tried to spin start manually to no avail

Could be a run capacitor for the motor but it is more likely the motor itself. Get a new motor and capacitor and replace. Easy job to do.

My brother works in heating and cooling..
And most of the furnaces.. ave a switch buttom on the side.. and that will make the blower work.. now another way that may be the problem.. is if the filters are very dirty.. the bloer won't ignite...
Good luck

Clean filters. Switch on the bottom of the squirrel cage? Thanks

Thanks. Should I try the capacitor first or replace both?

Since it has the death hum it is probably the motor itself. Replace both the motor and the correct capacitor for the new motor.
