SOURCE: furnace starts properly, then shuts down, led flashes 8 times

The first thing to look at is the flame sense rod.
Shut off power to the furnace, remove, clean sensor with steel wool or sandpaper then reinstall the sensor. Reapply power and it should run properly.

SOURCE: furnace flame goes low fan stays on

if the gas pressure is good on inlet and outlet of valve u might wanna chk the burner trays and manifold for flakes, dirt, spider webs ect... once u kno the passages are clear from obstruction you can focus on the mechanical. (sounds like gas valve may be getting weak and not able to open fully)

Check if 24 volts is being sent from the board to the gas valve, if not the board is nad and will need to be replaced, if there is 24 volts at the gas vlave terminals then the gas valve must be replaced.

Unplug your quick connect at the ignitor and chek to see if it has continuity. If it checks good start the furnace and see if you have voltage present at the quick connect. If ya ain't got volts going in then their is a problem with the board. Rich has a nice video at HVAC for beginners HERE

Heating Mode (Goodman Service Manual)

· The furnace control checks for an open main limit (this
limit is normally closed). If the limit is open, the furnace
will remain inoperable until the limit is closed. During
an open limit the circulating air blower will be
energized. The status light will blink four (4) times.
· The room thermostat reacts to a demand for heat.

· The control will then check to insure that the vent
pressure switch is open. If, at this point, the vent
pressure switch is closed the control will blink two (2)
times and will remain inoperable until this situation is
corrected.

· The venter blower is energized.· The vent pressure switch will close when it detects a
pressure in excess of its setting. If the pressure switch
fails to close the status light will flash three (3) times.

The sequence cannot continue until the pressure switch
closes.

· After a pre-purge of about ten (10) seconds the electronic
ignition device will be energized.

· After a slight delay the gas valve will open.

· The burners will ignite and the flame sensor will detect
the presence of flame. The ignition device will
deenergize. If the sensor does not detect the burner
flame, the gas valve will close and the ignition cycle
will be repeated for a total of three attempts. If, after
the third attempt, the presence of flame is not detected,
the furnace will go into a lockout condition for one (1)
hour. It will then repeat the ignition cycle. This one (1)
hour lockout and retry will occur indefinitely.

· Thirty (30) seconds after the main valve is energized
the circulating air blower will be activated.

· The furnace will remain in operation until the demand
for heat is satisfied.

· Once the demand is satisfied the venter will shut off,
and the circulating air blower will shut off after the field
selectable time off is attained.

· The furnace will remain dormant until the next demand
for heat.

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.

The whole assembly must be replaced.

The sequence of operation is -

Combustion fan purges the heat exchanger. A pressure switch verifies combustion air fan is running. Usually a 30-45 second purge before the hot surface ignitor glows, or the spark ignition starts.

Gas valve opens after 10-15 seconds and main burners light. Control board monitors for flame and shuts gas valve after 2-3 seconds if main burner does not light.

If burner does not light, some boards repeat this for 3 tries, then locks out and is reset by cycling power.

Air blower comes on after another 30-45 seconds after main burner ignition.

Times may vary based on the specific controller board. A flow chart and timing sequence should be located somewhere on the unit, usually in the fan compartment.
