[Chad Fabry]

I bought a Preston's guide but it's at home and I'm not. Would one of you nice folks help me please.

York furnace UG080D008N1B HM023678

State WH: PRV40 J96241600

The numbers seem self explanatory, but I'd like to double check please.

Thanks

Hi Chad,

The State water heater was manufactured in September of 1996. I'll see what I can find on the York.

This is the furnace. Other than a multitude of wiring that's done poorly, this roll out pattern was evident. The outside of the unit showed no signs of being hot, but it looks like there's a problem here.

I'd guess 1978, though it could be 1982. (In York coding, H=1978, M=1982)

The picture doesn't look like rollout. More like the small amount of spillage that happens sometimes at startup. After 20+ years of this, you'll see rust in this area. That in itself isn't a big deal.

Another very strong possibility is that the faceplates are cracked. Did you remove that flame shield? If not, turn around and bang your head against the wall three times.

The faceplates on that furnace are separating the combustion chamber from the circulating room air. A crack in the faceplate on this particular furnace is just like a crack in a heat exchanger.

That's why I like old York furnaces. No handwringing or waffling. Just take off two screws, point out the cracks and condemn the furnace.

Hi Chad,

I spent some time this morning looking through my references and couldn't find anything about York serial numbers, so I was glad when Jim had the answer for you.

I agree with Jim, you need to take off the flame shields (or puff shields as I've also heard them referred to) when you look at these. I usually find the cracks right at the corner of the faceplate behind the shield right in the middle of that area you photographed.

ONE TEAM - ONE FIGHT!!!

Thanks for the help on dates ..it's probably 1982. The house was started in 1981.

It's no trouble, I'd rather go back and take off that shield than go to dinner with my wife anyway (that staement is entirely untrue). I'll admit, after the panel where two breakers fell out because they were never clipped in and the gfci going south during testing, I was apprehensive about any further disassembly.
