Events to date:
*Resolved possible drainage issue
*Replaced filtrete filter with low resistance permanent filter (about 5 days ago).
**These resulted in unit working fine for about 5 days, but issues starteed again today.
*Have cycled the furnace about 5 times today. Previously, only saw code 14, but now I am seeing 34 and then after it tried the three times, I get code 14.
*Surface ignitor works, has a nice yellow orange glow that gets to max glow before gas kicks on.
*Gas kicks on, flames start up and stay on for several seconds, then go out suddenly.
*Flames are an even blue color and appear to be full flames, no flickering, no or virtually no yellow.
*When it fails, it is complete and sudden. Flames do not appear to starve for oxygen, they just shut off.

Would this be characteristic of a flame sensor? Is this a user serviceable part (I understand that the surface ignitor is not). Also, tech determined that voltage and current draw to the gas valve was normal.

This issues seems to become more problematic when temperatures are colder, and my furnace is in the garage, where it is currently about 40 degrees. (temp outside is 6 degrees)

Thank you for your help!

Yes, remove it, clean it with steel wool or emery cloth put it back in and be done.

Thanks

Thank you HarleyRider. Cleaned the flame sensor and it started right up with no shutdown...there was very little corrosion on it, but perhaps it was enough to affect it. I will see how it goes overnight.

Your very welcome......you clean your condensate trap and line, and keep that little bugger clean and you will have many happy years of uninterrupted heat.......of course change your filter as needed!

I cleaned one today with the home owner's (new and dry) dish washing pad, the green rough side of it. Lit right up and stayed lit. :thumbsup:

Cleaning the flame sensor seemed to help initially, but when to got cold overnight it sto0ed working again. Then after a couple of restarts today it worked all day again. Expecting a cold house in the morning.

Could the proximity of the intake and exhaust be a problem?

I had initially posted that they are a couple of feet apart (based on memory), but upon rechecking, they are adjacent. Could this be a problem? I will check the intake today; I know that they extended them both when we bought the house because they were next to the swamp cooler. When they did that, they did not put a hood on them. so the intake could have gotten something in it.

I'm having the same issue

I'm having the same issue with my WeatherMaker 9200. I opened up the front door of the furnace and see the flame sensor but it seems really tough to get to. Is there a semi-easy way to get it without taking the whole thing apart?
