>> Hi
>> 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 news.you 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 don't 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 flame.yada
>> 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 she's 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. Thanks
