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!
