A vent blower, aka draft inducer, is only one of a myriad of other safety designs within your furnace. The main furnace vent motor is meant to push air and dangerous gases out from the furnace.Some pros have referred to the vent motor as a draft inducer blower, it provides proper draft for a much more purer and safer combustion.

- The blower fails to achieve full speed
- A current is flowing to the draft fan motor yet the motor remains unchanged
- Draft vent motor never powers up all through the launch of the startup phase
