On - OK
1 Blink - Ignition failure. Check Gas flow, gas pressure, gas valve, flame sensor.
2 Blinks - Closed pressure switch. Check pressure switch (stuck in closed position).
3 Blinks - Pressure switch - failre to close. Check venter, pressure switch, vent blockage.
4 Blinks - Open limit switch. Main limit or aux limit are open. (My comment - Means overheating in chamber. Often result of blocked intake air. Bad filter. In my case, plastic wrap had been sucked into the intake. )
6 Blinks - False flame sensed. Check sticking gas valve.
Rapid continuous blinking - Incorrect twinning, incorrect primary polarity. Reverse transformer secondary leads, reverse primary wires.

Closed pressure switch can be from dirty combustion vents, bad chamber pressure - like missing screws, maladjusted gas pressure, failing pressure switch, loose hoses, moisture in the hoses or fan blades The switch need to be closed to ge the unit to work

Hi jmsocr2315,

If my description of what your heater is doing please read through to the end.

The heater is turned on and a room temperature is selected.
You can hear the noise of a small fan start, which shortly after the heater starts.
After a short period of time the heater stops and the red led begins to flash and shuts itself down.

This type of heater has a balanced flue, which means it draws air in one pipe and exhausts it out another.
Have the balanced flue checked for blockages, the problem will most likely be in the flue pipe which draws the outside cool air into the heater and not the flue pipe which blows out the hot air.
it may be full of cob webs or something else which restricts the air flow to the heater.
A service person can perform a quick test to prove the above theory. At the rear of the heater there are two pipes, one is an insulated metal pipe and the other is plastic pipe.
Disconnect the plastic pipe from the flue box and restart the heater.
If the heater runs normally this will confirm that there is a blockage.

Replaced pressure switch, ventor and unit still goes off on pressure switch. 3 flashes


Hello, check the small tubing that goes from the pressure switch to the inducer motor, sometimes it could be loose or blocked therfore not allowing the switch to close. Also, there could be some obstruction in the flue pipe preventing the switch from closing.

My Goodman furnace, model GMS80903BNA, is not working. I removed the back panels and checked the pressure switch. That seems to be working fine. The exhaust inducer spins up, the igniter starts to glow,...


That blinking 3 times is indicating a pressure switch problem. Try checking for water or a blockage in any of the hoses going to the pressure switch or condensate drain. Check the air intake and exhaust pipe for any blockage including any saggs that may hold water. Make sure condensate drain or pump is working. If you get a glow from the igniter, there may be a blockage in the gas valve or piping.

The led light blinks 3 times then pauses then


Pressure switch error code, Check the air filter for blockage, check the vent pipes for blockage or water, make sure the condensate drains are working and that there is no water in the hose(s) that go to the pressure switch(s).

Have a dayton gas furnace #3E463A spoke to hiltonjug last week. purchased new air sensing switch and new gas valve. just installed new air switch and green light is not coming on on control box????


Is the pressure switch tubing installed correctly???...no holes in it???....and the furnace ventor motor is running????turn off the power and wait a couple seconds...turn the power back on with a call for heat and observe...the ventor(exhaust fan) should start running/....the pressure it causes closes the pressure switch and should power the 24v circuit to the circuit board turning the green light on....if not....check your vent outside....it could be plugged...this will also not allow the switch to close ....clean the vent etc....if the vent is clear and ventor running....ensure that the pressurw switch is actually closed...voltage test....and if it is then that wasn't your problem....need more info really

Yes, check for obstructions. However, also check to ensure that you used an OEM pressure switch! See this video for an explanation: Amazon Furnace Parts: http://www.amazon.com/s/?_encoding=UTF8&camp=1789&creative=390957&field-keywords=gas%20furnace%20parts&linkCode=ur2&tag=amznelite-20

Goodman GMP075-3 Random Incomplete startup


If the draft motor starts then shuts right off and then a red light comes on usually means that there is a blockage somewhere. Check the pressure switch line, make sure that it is clear and the hole in the heater that the pressure switch vaccum line runs to is open. If that checks out then make sure that your flue vent cap is on and that it is not pressed down on the flue vent and that the gases can vent properly

Heater wont start Goodman GMP075-3


Check the fuse on the board. It is a 3a automotive fuse. There may be a problem in the control wiring. If the fuse is blown, make sure to find the reason why it blew and repair it. Otherwise you will need a whole bunch of fuses.
