Hi Guys
I have a Coleman direct vent furnace. The pilot light keeps going out. I blew out the orifice tube and cleaned the orifice, put in a new thermo-coupler, and adjusted the pilot flame. The pilot lights easily enough but when I get it to kick on, after it cycles and put out heat(the fans runs and blows warm air) it goes out. I cant see if the t-couple is glowing red or if it is directly in the flame. I suspect this may be a problem, that the t/c isnt direclty in the flame. It worked great for 1 day after I cleared out the orifice, adjusted the pilot flame, and set the t-stat at 70. Now it blows out every time. I am leaving for the weekend and very stressed out. Please help..

You guys are great, Merry Christmas!

Jim

Hello: Jim

Unless anyone can remember exactly the contents of your original question, this one stating "once again" implies a previous question on this problem existed. This question does not provide any background to the original question.

Therefore, it becomes difficult to follow along and not repeat what was already stated for solutions, advice, prior help, and what info was provided, etc. I.E. The thread losses continuity.

I will attempt to locate your original post and combine it into this one or provide a link to the original question to maintain the continuity needed.

First post is most likely this one:

Kindly use the reply button whenever the question pertains to the original post. Doing so maintains the needed continuity and avoids repeats and confusion..... :confused: Also helps to provide the best possible help you need....MERRY CHRISTMAS to you too.

If you have did everything you said. You might look at the heat combustion chamber for any cracks. Have had units that have had them in it. Thats like some times have had to go out and cover the outside vent up tight just to light the pilot then close the inside tight and then uncover the out side vent. The pilot would stay on. But if you have a crack in the chamber it can blow out the pilot on you after a run. I dont know of any recall on the unit you have .I did have a recall on some other gas baseboard direct vent heaters we had put in. The combustion chamber had cracks and would blow the pilot out. NOW IM not saying this is what you have .Just take a good look at it. Did the new thermocouple look just like the old one and fit in and up as high as the old one?
