I have a coleman furnace it comes on the electric igniter glows red the gas comes on then the blower starts and the fire goes out it gives 2 different code for this 1 is ignition failure and the other is...

I would have the ignition control board replaced. That is what tells the gas valve to come on and if there is flame or ignition it will keep the gas on if the flame sensor gives the board a signal that the burner is lite. By you shuting power off and on to the furnace it resets the board and it will go through its cycle again.

I have a 15 yr old armstrong furnace, it wont lite all the time on first try,repair man has replace the smartvalve,igniter and the sensor, the enducer motor comes on then igniter gets brite orange then it...

Has your repairman checked the pressure switch that senses when the inducer is running? Often times when this happens it is the pressure switch or there is something like water in the exhaust piping that will keep it from working. Go to the outside of the exhaust, if you hear water gurgling than you have a problem there. Make sure that the intkae air pipe is clear if you have one. It is okay to pull if off at the furnace tempoarily to see if it works without it.Check the small hoses going to the pressure switch to see if there is any water in one of them.
Just some other things that you can check to see if you can find the problem. It really should lite off on the first try, but yes, it wil try three times before locking out.

Armstrong furnace ultra 80sx doesnt always lite on first try,service repair man replaced smartvalve,sensor and igniter he says its ok if it doesnt always lite on the first try ,sometimes it takes three...

Sounds like your gas valve is sticking. Your repair man is somewhat correct by meaning that the furnace will attempt to start 3 times before going out on "Lock-out". The furnace is reaching it's expected life and you will start experiencing more frequent issues with it. Check into some of the incentives to get a replacement with a higher efficiency rating. The newer units have greatly improved in performance as well as comfort.

Heater does not stay running shuts down may or may not come back on

I hope your pool heater is still running! Anyway you mentioned that when you reinstall the heater door the heater turns off.

This is my personal experience with this; there is no switch on the door, keep that in mind; so ask yourself: when you remove the door are there any wires touching or resting against the inside door panel?

if so its possible that one of the wires in a connector is broken, the crazy thing is you cant see the broken wire that is causing your intermittent issue.

What I did was cut off all of the wire connectors and installed new ones, now the heater is running like a champ.

Good luck

Charmglow pilot won't light at all.

I would say that the lines still need to be perged. This some times takes a few times to get it going . If it has set for a long time or have run low on only takes a little air pocket to stop the works. Ask the man back. $125.00 is a lot of doe for no go. DFD

Heater will not stay lite

Sounds as though your heater is a bit different than mune - I havwe no gas supply button, at least I don't think so. I just replaced my nozzle however at the recommedation of a recent contact to this site. It worked. The replacement packaging suggests annual replacement, so I think I was due - after ~12 years!
