Furnace starts up blower starts..nothing ignites...then shuts down. repeats and doesnt stop...sanded igniter stick and nothing happend. flashes red once.

Do you see the actual ignitor glow? You must be saying that you sanded the sensor. The ignitor, after the little inducer fan comes on will begin to glow a bright orange until the burner lights. If the ignitor is broken, you will NOT see a glow, and you may smell a faint smell of gas.

Air pro gas furnace model #g8c07512mub11a The combustion fan comes on the igniter glows red the gas fires in the burners for 5 seconds the it shuts down. Any suggestions would be helpful.

I would suggest you change the flame sensor. It will be a small diameter probe extending into burner compartment,usually over or inbetween burners. If your furnace is lighting the burners but they won't stay lit That Is what I would do first.. I also would turn thermostat to fan on to make sure you don't have a problem with the fan. Hope this helps you. Thanks

goodman furnance the exhaust fan starts, igniter glows hot, all burners lite up & will burn for about a minute and shuts down . I think it senses the room blower does not start so it shuts down.

No ignition and E04 Code

The HSI (ignitor) has 2 wires, its like a cigeratte lighter, power is applied and it heats then glows red, the single wire you mention is the flame sensor, used by the control board (igntion module) to ensure the burner has lit or it shuts the power to the gas valve off but keeps the fan operating for a period of 1 hour till it resets.

It sounds like your ignitor is defective, it happens often, depending on your location, you may be able to purchase one, but I would advise having a service tech do it.

The manual for troubleshooting and repair can be found at this link:

Heater starts and then stops.

I will keep you posted. I have aquired all the service manuals and I am in the process of taking the heater apart. It is not the motherboard.

When I start my heater it ignites but goes right back out in about 2 - 5 seconds what is wrong withn it

First of all, when you start the pool heater the first thing that it does (I am talking about Jandy) is to start the Exhaust Fan to evacuate all the fumes...Is this happening????

After it does that, then the igniter glows and usually takes 17 sec before it reaches the temp.... Can you see it glowing through the eye glass???

When it reaches the temp, the Fan start in a low speed, then the gas valve open and is when the Natural Gas or Propane goes into the burners creating Flames.... If this happening???

Then, the flames are sensed by a "Flame Sensor" which if for any reason it does not sensed will shut down the pool heater... have you check the Flame Sensor????

Well, lets say the Flame sensor is fine and the gas ignites and you have a perfect combustion, so after a minute or two the Exhaust Fan is going to work in a high speed to evacuate heat and Fumes, but also it will shut down the heater if it can't kick on giving you an "Air Flow" message in your screen.

Check this and see if that gives you some ideas how to find the problem. If it does not work, I recommend to call the manufacture of the equipment an talk to then directly.

Good luck!

GMT 115-5B wont ignite

couple things without more info is little hard,,,first not familliar with this paticular model but I believe it has a glo igniter,,which will be located next to the burners,,should be one or two scres holding it in,if this is not glowing than u need to pulll it out and look for a crack in it if its cracked u need to replace. If this is electronic ignition will have a metal spark ignition,,the glow ignitor will be ceramic by the way,,also if u pull out the glow ignitor do not touch the element with your hands while inspecting or replacing for the oil on your hands will cause it to fail sooner. sorry back to the metal spark ignition if it is not sparking than chances are u have a problem with the combustion fan motor shutting down the gas valve before it lights. I just posted on a goodman about the fan motor and the two types and how to fix. good luck.

After a few heating cycles the burner does not ignite

The problem you are describing is usually associated with a bad gas valve coil. The dryer runs normally until it gets hot, then starts making a strange clicking noise. After it cools down, the dryer runs normally again. The gas valve coils (there are two of them) usually run about $20 a piece. I recommend replacing both of them at the same time just to be sure. I hope this helps.
