A constant red light (not blinking) indicates that the thermostat is not calling for heat. Of course you know it is but just to be safe, jump out R and W on the board. If it continues to do the same as you indicated, replace the board.

I have a Goodman GMS9 furnace. When the furnace starts the induction fan runs for about 15 seconds, the ignitor turns on but thats as far as it goes. The burners do not light and I don't think the gas...

The igniter heats a thermocouple to turn on the gas valve. From your description, the thermocouple may have failed. The noisy stack blower probably needs to be replaced but its controller may be in need of replacement as well.

I would guess that the fan off setting on your limit is set a little to high. If you have the manual you can see what it says about changing the running time for the fan after the burner has shut off look on the control board and you should see two switches,one to set the time for burners to fire before main blower starts and one to set time for fan to run after burners shut off. To help with the problem you are describing set fan run time up so fan wii run longer. Hope this helps. Thaks.

Goodman GMP Furnace problem. Original problem is

Good one! Is the flame getting to the flame sensor within the few seconds? Maybe a good cleaning of the burners or flame tray would help. 1.3 ma is enough for the flame rod to tell the board to stay on. Re-do all the ground connections both at the board and furnace cabinet to be safe. Check the polarity of the power going to the furnace. What are the chances the second board is bad?

My furnace heats the house well, but during the cool down it actually blows cold air dropping the temperature causing the furnace to re-ignite. How do I adjust? Goodman - GMS9/GCS9

Depending on the age of the furnace you may be able to adjust the cool down. On some furnaces there is a silver box usually made by honeywell. This is your fan limit control. If you take the cover off you will see a dial with different temperature settings with 3 pins in a grove. The first one is fan on with temperature rise this turns the blower on when the furnace starts and warms up. The second is the fan off after furnace shuts down, this would be the one you want to adjust to a higher temperature to keep the blower from blowing cold air. The last pin is the high limit if the furnace gets to this temperature it will shut the furnace off but keep the blower running. Make sure that the thermostat fan option is set to auto and not on.

Model #GMPN100-4 Goodman furnace. Vent fan

The sequence of events for furnace operation is -

Fan purge for 30-45 seconds. During this time, a pressure switch is actuated by the running of the purge fan, proving the control board the purge fan is running.

After purge and purge prove, the hot surface ignition and or spark begins. After a few second delay, the gas valve will open. The control board then monitors for flame prove through another sensor located near the burners. If there is no flame within 3-5 seconds, the gas valve closes. It will repeat this process, usually 3 times, before it shuts the system down, which requires a power down of the system to reset.

I have seen trash get into the hose between the purge blower and the purge switch. But you could be having other problems.

I have outside Goodman-Janitrol furnace and air unit and

two things to try first to get you pointed in the right direction. First disconnect the R or RH wire from the T-Stat. If the furnace turns off (Stops firing w/ fan to turn offabout 90 sec. later) then you more than likely have a bad Thermistat. If it continues to run Pull the R wire from the Furnace circuit board. put door back on furnace if it stops you have a short in the wire. Still Running? Most likely a bad curcuit board. Hope this helps.

Fan and heater run fine but fan does not shut off for a long time

Check the diagnostic indicator.
1. If the blower runs for hours make sure the fan switch on the thermostat is set on "auto".
2. The furnace safety system must be in lockout. This is the furaces way of telling you there is a problem.
3 Most common problem is a dirty flame sensor.
