If you look at the wiring diagram in your furnace you will see that 4 blinks means there is either a blockage of air or your room air blower is not working. Check the air filter for any debris first. Then test the room air blower to see if it turns on and blows enough air prior to going out on code. Are all the dampers open both in the pipes as well as at the registers?

Can you give a sequence of events description as to what it does? A 1 blink code just means ignition failure, but without any more details, I cannot help.

Ignition failure.


if furnace fires up then immediatly shuts off check the flame sensor. make sure it is sitting far enough inside the burner box and has proper continuity. if ur getting ignition failure without having furnace fire up, check proper voltage to hot surface igniter, continuity within igniter

Four flashes on Goodman GDS80904BX circuit board


I have this clunker-4 flashes is an open high limit code according to the wiring diagram and fault code sheet. the common denomonator for this furnaces problems is the circuit board. Always flashing 3, 4, 7 times most of the time having nothing to do with the problem. The actual problem is the board it's self. take it off the mounts (POWER OFF FIRST AND SWITCH OFF>)
remove from the 4 mounts one at a time then check the back of the board. you will probably notice brown spots on the green. this is where the board has burned up. replace the board and you will be fine, you will also be the 100th person I know to have this problem. Make sure you take a picture of the board before you take all the wires off so you can put them back properly. I personally have replaced the board twice the first replacement I purchased (warranty) was made by the same company as the original, the second board I replaced 1 year later with a new board made by a new manufacturer. they obviously knew there was a problem.

this is a picture of a board another fixya user sent me today after he had the same problem as you and I told him what to look for. look familliar?

Goodman gmpn100-4 ignitor lights, burners don't ignite


1 blink is ignition failure
without being able to do voltage checks
i would reccomend checking your igniotor, if you can put an amp meter on it, it should read 2.6-3.4 amps
if you cannot do that, Or check voltages I woudl repalce the igniotor, gas valves do go bad but very few and far between....
at the risk of a bad rating you deserve at least an answer...
if i were called to your house with this complaint I woul not bother comming with out the ignitor
just because the igniotr looks likes its hot,, it may not be hot enough to safely open the gas valve

Gmt090-4 furnace the igniter and gas valve relays both kick out when the gas valve tries to kick in


This unit is equiped with a diagnostic light and will blink a number of times indicating where to start looking for the problem. Find a small viewing port that looks right on to the control board. Count the number of blinks. Then find the wiring diagram and there will be a diagnostic chart where you can compare what the number of blinks represent. Let us know what you find.

Coleman furnace wont fire


Check inside the door panel next to the wiring schematic, you should find the diagnostic codes. Look up 7 blinks. This should narrow down the problem. ( It sounds like a bad hot surface ignitor).
Good luck.....

Goodman GMP075-3 Has 1 single blink on the light


The blink codes are differant on every furnace. Read your code on the schematic found on the inside of the door. You most likey have a dirty flame sensor. Under the burners you should find a "single" wire going to a connector. This will be to the far left or right. Just opposite of a "two" white wires going to the hot surface igniter. Remove the 1/4 inch screw closet to the single wire under the burner. carefully pull out the flame sensor. Clean it with a small piece of sandpaper. Re install it. This should fix your furnace. KEEP IN MIND Goodman GMP models are noted for defective heatexchangers. Pull out the blower assembly and turn it over. If small rings about the size of a dime falls out.... this furnace is unsafe and should replaced!

Model GMP100-5-REVA


You could have a limit switch that opened. On the reverse side of the furnace access panel there will be a diagnostic chart indicating what 4 flashes indicate. If it is an open circuit, why is it open? Did the unit get too hot and why? Unless you have the diagnostic capabilities, call a professional.
