The Power Venter (also known as Heat Inducer and Draft Inducer) will not start.

FURNACE:
Made by: Goodman
Model #: GMPN080-4

THE POWER VENTER (this is what the Goodman manual calls it but other websites refer to this as the Heat or Draft Inducer):
Made by: FASCO Industries 70219565
Type: U218
Volts: 115
RPM3400
Customer Part #: B2833001S

I have been troubleshooting this all day and this is what I have learned:

The Thermostat is ok.
The Indoor Blower (Main Blower) is ok. I can turn on just the fan from the thermostat and it turns on.
Everything was working fine and then something happened. I have not moved any wires or made any changes.

Here are the sequence of events:

I turn on the heat from the thermostat.
The Thermostat clicks telling the furnace to turn on the heat.

The furnace has a humming sound coming from it. This is the Power Venter/Heat Inducer trying to turn on. The indicator light blinks three times. The panel explains that this means:

"Pressure switch failure to close. check venter, pressure switch, vent blockage"

The humming sound will stop and then begin again but nothing happens. Also during this time a burning smell is coming from the power venter. It smells like burnt plastic but I am not sure what it is.

I attempted to move the fan blades on the Power Vetner with a screw driver but the fan blades are not accessible.

My next step is to remove the Power Venter, open it up and clean it.

Any suggestions will be greatly appreciated!
