Watch out for the older Smart valves and the 15+ yr old VR8xxxH Honeywell valves. The regulators are failing and overfiring the burners. Had a 16 yr old NUG just about roast me the other day. Flame lifts off the burners due to overfiring, gas continues for 1/2 second and spark comes back on and you get blasted. Don't EVER stand too close to the front and turn it on/off with the door switch or you can get burned!!

Unfortunately, this furnace is 130 miles from where I live. This is in a hunting cabin. Earliest I can get there is this weekend.

I was hoping to get a few ideas and buy whatever parts I can while I'm still in a major city.

I'll get the serial number this weekend. I really need to get this thing working reliably so I don't have to disconnect all my water, as I won't be back for a few more weekends and it'll definitely be below freezing by then.

I bought the furnace new in the box last summer. I know it's about 8 or more years old, but it was sitting in it's box in a warehouse all these years.

Can someone enlighten me on this Smart Valve? Would that cause the exhaust motor to engage, but not ignite? Is this something that I could replace myself?

Too late. I put a new igniter in a Consolidated furnace of like vintage and pu the power to it.

Lucky for me I never stand in front of the furnace when i make a repair.

That sucker belched flame across the room. I turned down the gas pressure to about nothing and the meter still clocked 60k (had put this furnace in back in'95 and it was an 80k).
Cut to the chase. New Gibson 72k direct vent 90%.
Still have the valve.

Anything interesting if i open it up?

The Smart valve has SV****H or M stamped on the front of it. (SV for smart valve). LOTS of problems with them. If you have one in may never be reliable. They discontinued them. Sitting idle for many years is not a good thing as the valve may get sticky internally. There are several other versions of the furnace with spark ignition or a glow coil. You would need to take a pic of the burner for us to know which one. No point in buying parts. ICP/Heil is 'fond" of changing their burners/valves every couple of years so we need to see it to know which one you have. For a remote location like yours an electric furnace would be 1000 times more reliable. Not hard to change sequencers and they VERY rarely breakdown.

No. Read the above posts. We said there is too high a probability for diagnostic error with out seeing the furnace Too many variables on this type
on this type unit

thanks guys - I appreciate all the feedback and understand it's impossible to troubleshoot with the info I've given.

I'll get pictures, serial #, etc and report back sometime this weekend.

Guess I'll plan on disconnecting the water this weekend. :-(

OK, my father and father in law made a run to the cabin and I'm still back in the city.

When they got there and flipped the breaker the furnace fired up and worked fine for about 5 minutes.

Now it's back to the same old thing. They killed the power, let it sit for a few minutes. The first time, the exhaust fan kicked in and the light on the board was blinking. No pattern, just blink, blink, blink..............

Killed the power again and restarted. Fan kicks on and now just a steady red light on the board. No blinking at all, but still won't ignite.

The electronic ignition is not engaging either. Normally, you can see the "glow", but just the fan runs and nothing else.

Here are the specifics:

Mfg# NULE075BG01
Model # 867778381
Serial # L912477394

Any and all suggestions are appreciated. I've got them up there until tomorrow morning and will have them try whatever is suggested. It's only in the low 40's daytime there, so hopefully I can get the old timers some heat.

OK, we've ruled out the pressure switch which was my self-diagnosis. If you remove the tube from the back of the swith, the exhaust fan shuts down.

Running to town now and going to try a new ignitor. It'll be another couple hours before we do the round trip and see if that gets us ignition.
