    thanks for answering, but if u can tell me what the leds on the board means, the actual furnace or the thermostat itself. and the gas valve that u r referring to, r u talking about the giant knob goin into the furnace or a smaller one inside the actually leading to the pilot? sorry for asking simple questions, but your help is greatly appreciated!

  • itsallgravy0 Mar 12, 2009

    ok maybe i should of worded it different. "Where is the board?" u mean the thermostat? or down under by the actual furnace? i do see the knob in which ur talking about for the gas. but it does light up, and burn for like 10 seconds and shuts off, and tries to restart like 3 times after that. should i try and clean the flame sensor since i havent the 3 years i lived here? lol and where would that be located?

    Thanks for responding in my time of need, i will check it out. another question if you dont mind answering, this only happens when the heat is was already running, and then i call for it to go longer, if that makes sense, then it will have trouble keeping the gas on. do u still think its the gas valve? i would probably need a techinician to fix it wouldnt i, i not to fond of blowin myself to smithereens lol. u have been a lot of help and i thank you for your time, u have narrowed my problem down to a couple of things instead of a whole new furnace! :-)

It should have a diagnostic set of leds on the board, with the code list on the door and the control board itself. If it get to the pilot stage and the shuts down its most likely the gas valve. You can check for continuity from mv to c on valve, you should have it. Then with a valtage test from mv to a ground or common as you here the next click of a relay on the board after the pilot has had a few seconds.

    Yes the gas valve is the aliminum box with a knod or on off switch are located. When your furnace fails to ignite it kicks the fan on to purge area. There two leds the first is the first digit of the fault code the second is the second digit. Look at the control board closly the code list is there or on a panel somewhere.

    That particlur gas valve has a main and pilot circuit just becauuse one does doesn't mean the main will.If it never fully ignites the flame sensor has'nt came into play yet.

Check the pilot light sensor. Have seen this issue before. Sometimes after lighting need to hold it in longer. If it doesn't detect the lit pilot wise it will sit in safety shut down mode

Lennox G8Q3-90-4 will not ignite the pilot. The

While holding down the control knob for the pilot, you either have to use the pilot ignitor or match light the pilot. Then old the knob in for 60 seconds, before releasing it. If the pilot remains lit, turn the control knob to ON. If the pilot does not remain lit, the Thermocouple or Thermopile may need to be replaced.

Hope this helps you to solve the problem.
