Flame roll out problem with Williamson gas furnace.
QUESTION:I recently purchased a home in north central Florida. It started to
get close to where I would need to be running the furnace occasionally
so I decided to fire it up for a test. I lit the pilot switched on the
heat and the burner fired right up. Manually turned the fan on to make
sure there were no gaping holes in the exchanger. No disturbance of
the flame. Switched unit off, gas valve shuts down, flame goes out no
problems. Button everything up and closed the closet door. Fire up
the furnace ,we have ignition. I let it run long enough for the fan to
come on and then I bring the temp down to shut off the valve . As I'm
doing this I hear a definite "click" then "whump". Houston we have a
problem! I have two gas forges, two gas fired crucible furnaces and
two gas fired kilns at my business. I know the sound of "whump" is not
going to be good. I open up the closet door and panel and sure enough
I have a mess of burned wire. The house came with a warranty so I
thought now's the time to use it. I call the company and they send a
technician. I explain to him my experience with gas systems and throw
out a couple of juicy burner terms so he doesn't treat me like an
idiot, and to give him a chance not to stick his foot in his mouth. We
open the furnace up he looks at the burned wires, pulls out his
Nextel and calls the boss. Like a miracle, due to the magic powers of
the Nextel, his boss determines it's a cracked heat exchanger and he'd
have to change out the unit. Man that guy's good. Actually at this
point I'm getting pissed but I'm a nice guy and I figure I'd let this
play out and see where it goes being as it's under warranty. The good
newsyou get a new furnace .. The bad.. It's $1200.00 extra to bring
it up to code. Now I'm mad. Not at the $1200.00, that's a code issue
and I understand, but at the lack diagnosis. Freeking parts changers!
Ok I'm now going to fix it myself since I dont have $1200 extra right
before Christmas. I rewire everything and run the unit. Cycle it on
and off a few times, everything working great. Nice ignition of the
burner with minimal amount of roll when it fires. Good steady
flameyada yada.
I certify this unit operational!!! I didn't change anything but the
wires, but hey you never know. I've had the magic touch before. I
close the closet door and about a minute later I hear my old friends
Mr. Click and Mr. Wump. Unfortunately my wife was standing there and I
had to hear " this isn't one of your kilns this is our house!" Always
work on your furnace when your wife isn't home and preferably when
shes out of town. This will give you time to repaint the room and
replace the cat.
Ok at first I though it was a faulty gas valve that wasn't closing all
the way and figured I would replace it as a safety measure. But after
reading up on things I'm not so sure, the closing of the closet door
seems to be a factor which leads me to wonder about the air intake.
But then there's the unmistakable "click" right before it happens. So
I'm not so sure. I'm open for any suggestions you might have on this.
Also is it possible to retrofit some sort of rollout protection?
Thanks for reading this and I'm not really down on HVAC techs. I
actually like the guy's I dealt with. I just wish they would have done
a little testing (or at least threw some chicken bones on the floor)
before they declared my unit dead. And it may very well be.
ANSWER: What was the whole point of this long boring story? Are you just wanting
reaffirmation that you are indeed a complete clueless cheap asshole?
The only think I could see is that you provided compelling evidence that you
obviously do not understand the operation of gas-fired appliances, and you
also are a cheap homoaner bastard who could never receive satisfaction from
any HVAC service technician, including Jesus Christ Heating and Cooling.
The fact that your stupidity will probably cause you to do harm and/or death
to yourself is not a problem, except that you indicated that you also have a
wife and possibly children living with you. Because you blatantly endanger
others in your household, and you have admitted doing so in this public
forum, you are now subject to investigation by Child Protective Services, as
well as surveillance by other law enforcement and insurance fraud agencies.
