Question about Heating & Cooling

Open Question

Goodman GMP 150-5. Appears that the gas will not flow to the ignition. recently had it brought up to code (rigid pipe in the burner chamber) and now it will not light. I'm wondering if there is anything that would stop the flow of gas to the burners besides the on/off switch. There is a copper screw that is not aligned as the diagram indicates and I'm wondering if that is a valve the could be preventing the gas from flowing.

I have the same problem. The middle and the right burners will work, but if I light the left side (3rd burner) all 3 go out. pressure is reduced to zero.

SOURCE: I have a Goodman gas

On your flame travel tube sometimes something gets in that and blocks the path. Now this is what I found one time when same problem happened.

I took it apart and found a dead **** roach in the path. Took the bug out and it worked perfectly.

I don't think you have to take it apart just take something and run in the path like a tooth pick or a small screw driver. Maybe a air compressor air gun just enough to blow the path out. let me know if that helps you. ken

I hope this is what you are talking about as I read your post 2 or 3 times to get a idea of what it is exactly.

SOURCE: One burner igniter fails to spark after getting wet

Each burner has its own switch to direct current to the igniter. It appears that one of the four switches burned or shorted out, while the other three survived the flood. These switches are replaceable, so that's how I'll fix the problem.

Hello, sounds like you are referring to the burners. Usually when this happens the whole burner assembly must be cleaned, spider webs and dust clog up the burners.

Furnance goes on won't fire


Hello, if the burners do not fire at all there could be a few reasons, the igniter could be bad, the burners could be dirty not allowing gas to flow, the pressure switch could be open. There should be a led light code on the control board that will tell you where to look. Begin by checking the hose between the inducer motor and pressure switch, it could be loose, kinked, or have a obstruction in it such as water not allowing the switch to close, also check the flue pipe for any obstructions. If the switch checks out good than the igniter should be inspected for any cracks or white spots, this is a sighn that the igniter is weak and should be replaced. If the igniter is good then clean the burners.

Goodman GMP 100-5 Rev B Serial # 9902602550 The status light stays illuminated. It isn't blinking. I believe my igniter went bad. When I turn on my heat on the system, The exhaust fan kicks on,...


Hello, the first thing is check the igniter for any crack or white spots on it, also, if you have a multimeter check the resistance of the igniter, should be between 40-90 ohms. You can purchase a igniter at any Heating and Cooling supply store.

I have a Lenox furnace. Before this igniter kicks off, there is a loud noise comes from furnace. Where is that noise from? Thanks.


This is what we call a "delayed ignition",(gas is not being ignited right away), gas builds up in the chamber and then lights causing a boom. The cause of this problem could be from having dirty burners or ignitor not position to ignite the gas right away or your ignitor may not being glowing enough to ignite the gas being released, check all, Good luck.

Won't ignite


Be sure that that PVC vent pipe going outside is not plugged or trapped with water. If the vent pressure switch is not tripping the furnace will not ignite. Also be sure that you don't have a gas leak somewhere causing weak gas flow to furnace.

Goodman GMP 125-4 one blinking light code. Gas valve has been replaced (at cost of $443). Didn't fix problem. Same co wanted $415 to replace circuit board. I did it myself for $99 part. Still same problem!...


One blink means it didn't light after a number of attempts. You replaced the circuit board and gas valve. Read on for some suggestions. On a call for heat, the 24 volt thermostat sends a signal to the control module. The control module will indicate a call for heat with a light on the control either blinking or remain solid depending upon model. The inducer (exhaust) blower will purge all gasses from the furnace and pressurize a pressure switch. Once the pressure switch tells the module to continue, the electronic ignition will energize and send 120 volts to the igniter. The igniter will glow and you will be able to see it if viewed thru the small inspection port. Once the igniter gets hot enough, it sends a signal to the module opening up the gas valve (24 volts). Either a pilot will come on or the burner tube will ignite then spread the flame to all burners. Lastly a safety sensor will be looking for a certain temperature within a few seconds and the furnace will continue to operate and the room air blower will turn on in a minute or two.

What could go wrong? The unit will not run if there is no signal from the thermostat (bad thermostat or broken wire), the control module does not sense a signal from the thermostat (bad control), the inducer does not energize (bad motor), the pressure switch does not close (blocked vent piping, bad switch, plugged condensate hose), the igniter does not energize (bad control, bad igniter), the gas valve does not open or there is no gas (bad gas valve, broken wire, no gas), the pilot does not light (dirty pilot), the burner does not light (bad burner, plugged orifice, not enough combustion air), the flame does not spread to each burner (bad flame spreader, dirty flame spreader, more bad burners), the flame safety sensor does not detect flame (dirty or bad flame spreader, bad flame sensor, broken wire, bad control), or the room air blower does not energize (bad fan motor, bad control).
