Re: goodman gas furnace power vent motor and housing...
You need to type GOODMAN GAS APPLIANCES into you browser to find you local servicecenter. I must tell you that Goodman only sells to authorized service companies in my experience. So you become EgKraft Company.

Gas furnaces has safety features to prevent explosions. If anything is thought to be faulty, nothing works. All gas appliances must be repaired by a registered gas technician. The two pressure switches are $76 and $29 if you want to risk it.
Typically the filter is located externally of the furnace. If not the lower door near the blower housing. Turn off the power to the furnace 1st. and open that door to look for the filter
it could be condensation. or poor seal at roof. probably the seal at roof. also check the larger copper line is it sealed good? if any spot is not this will cause leaking when in cooling mode. maybe dripping from line onto vent.
The problem is too much gas as opposed to not enough air. It is still running rich. Did you take into account the elevation of the location your furnace is installed at. The higher above sea level the less air that you have to aid in cumbustion. The condensation is from excess gas being cold and causing water to accumulate. Can you run it like this? Yes but it will cause issues with soot and carbon deposits. It will also cost you more money in the long run.
from my experience with goodman units ,it could have been a gas supply problem there are so many protective sensors that i dont think it is the unit by the way is it electronic ignitor or pilot
It is probably not the glow coil, if this is a 80% regular
furnace, Make sure the induced draft blower is working. I once went to a house where I came across
this problem, the only difference is that it would acutually start and then shut off. I took the vent apart
at the furnace and found a bird that was preety cooked.
If this is a90% High Eff. furnace, make sure the pvc
vents are not plugged. To troubleshoot the intake
Vent. Remove the combustion plate and then turn
the unit on, if it runs you have a problem with the
intake vent.
You could temp. remove the exhaust vent and then turn on the power if it runs then your exhaust vent
is probably plugged. You could go outside and make sure the vents are free.
Make sure you have gas available, these are the most commom issues that could solve your problem
If this is a High Eff furnace:
1) Remove the compartment that has the igniter and burners, turn the
power back on, if the furnace lites then you have a problem with the
intake air vent, probably iced over if you live where its cold.
2)Make sure the exhaust vent is not getting backpressure from the
wind.
3) you could cut the pipes on the inside of the house to disconnect them from the furnace, test run the furnace with no pipes.If the furnace
runs then you have a problem with the installation of the vent pipes.
4) Do not run the furnace without the exhaust pipe disconnected,
go to the hardware store and get a couple of rubber clamped
couplings and hook-up the exhaust pipe!
Based on your description I would guess that there is a "leak" somewhere between the gas valve and the actual fire. Use soap bubbles to check the connections at the gas valve. Also check the gaskets in the Gas valve the same way. Lastly there may be a cracked or misaligned burner causing the "leak". Best of Luck!
Most likely either a bad board or no gas to gas valve. Bleed out all air in the gas line. Check for 24 volts at both gas valve and circuit board terminals leading to gas valve. No voltage = bad board.
