Furnace will ignite but blower won't come on so furnace

Customer Question

Bryant furnace will ignite but blower won't come on so furnace stops and then locks for 3 hours. Error code 33 "Indicates a limit, draft, Safgbuard, flame rollout, or blocked vent switch is open. Check for restricted vent (none found), loose blower wheel, excessive wind (not) dirty filter or restricted duct system (no)....inadequate combustion air supply (not). Is there a reset button or something to try to kickstart the blower? It appears that it never engages.

there was a Bryant circuit board that had a blower glitch. It would turn everything on except the blower motor.

But it must be first determined if the motor gets power but doesnt run....or doesnt get power to run.

Do you have a meter or comfortable getting into the wiring?
