My Goodman furnance blowing cold air.I have 4 LED flashing lights


Reset the power to see if the furnace tries to light. If it tries & fails, it is an ignition issue ie hot surface igniter, dirty flame sensor. If the LED's still are lit up, it is most likely a limit that is open.

1993 goodman status light 4 times blinking


Witch blower is running, the inducer or the systems blower?
System blower could mean the the high limit is opening and shutting down the systems gas train, I would check this out first.

The other problem could be with the pressure switch for the gas train, it is supplied from the inducer motor, check to see if it is operating fully.

HSI boards do go from time to time, this sounds more like a system control problem.

Goodman # GMS81155CNA light blinks 4 times - furnance won't light and blower runs all the time - it's cold - please help


Hi,
The 4 blinks means that the high limit switch or the regular limit switch are tripped... try to find the high limit switch... it is usually near the blower...there will be a red reset button in the center of it... push it in and the unit should work again...
if the regular limit switch is kicked you may have to replace it for the unit to work again...
This often happens after a power failure if the unit was running at the time of the failure. If you did not have a power failure, then find out why the limit switch kick out...

Here is a tip that will help you try to figure out why yourfurnace is not working.

Service indicator light flashes 4 times. High limit switch?


There should be a diagnostic chart on the reverse side of the front panel. If in fact it is a high limit issue, check your air, condensate hoses and blockage of return air from the ductwork.

What about the safety limits for over heating? You have tackled all obvious problems, I am only throwing this out there because while the high limit is jumped out, to get the open high limit is definitely strange. So i would be tracing my wiring backwards from the relay to see what else is in line with it. This is not a solution but only a suggestion before running out to purchase the main control board, as most places will not accept a board back if that is not the culprit. Good luck with this one it leaves me slightly puzzled??

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.

My furnace blows cold air constantly even in heat mode. It's led light flashes 4 times in a set, what could it be?


On Goodman furnaces, 4 flashes usually means open high limit. Look for any burnt or loose wires or any resettable limits, they should have a red button that clicks when you push on it and wire going in and out of it with spade clips. If the open limit is not resettable, jump it out to verify its open and if that fixes the problem, replace the defective limit. Best of luck.

I have a goodman gmp075-3 and it is flashing # 4 code


There is a Primary High Limit Switch towards the middle of the furnace, it more than likely needs to be replaced, very common to go out only after a few seasons. Also, you could have a flame rollout switch tripped that will signal the same code, these switches are re-settable and are located on the outer, top and sides of the burner assembly, they’re about ½ inch in diameter with a red push button in the center and two wires “ usually purple” coming off of them.

Hope this helps

Code continous flashing


If your igniter comes on but no ignition, that eliminates the possibility of a bad or clogged pressure switch, high limit or flame rollout switch. Sounds to me like you have a control board, or a gas valve going bad. Could even be some loose, corroded, or faulty wiring. Before the igniter comes on the furnace does a self diagnostics to ensure everything is working, or the furnace will not make it to the igniter sequence. Inducer motor, pressure switch/s, limit controls are closed…then comes on the ignitier, gas valve opens, pilot runners and burners ignite, flame sensor detects the flame, blower comes on and all operations are working.

Hope this helps
