Maybe Justin can offer the HVAC company some free advertising on the OC, if they fix his furnace for free.

You were already warned once about posting sexual content on OC. If it happens again the adsense Gestapo will be knocking on your door.

My brother in law pens am HVAC business. My suggestion would be to start an HVAC business.

My flame sensor went last year. Same issue. I took sandpaper to it and it worked fine.

Unplug it and plug it back in.

Gooby pls

Not sure if this will help, but my furnace has a light that blinks in a pattern. On the inside of the panel is a list of codes that you can match to the pattern to see what error code it's giving. Right now it blinks 3 fast and 4 slow which according to the panel is error 34 ignition proving failure. Whatever the hell that means.

Ungrateful byatch.

Sounds like your thermocouple may be shot.

I think its time to call a furnaflamesensorceress.

Indeed. I've seen enough of the Paranormal Activity movies to know that if he lives there ONE MORE DAMN NIGHT, there will be a demonic possession followed by everyone dying.

He must have fixed the problem, we haven't heard anymore about the furnace. It is amazing that when you pay your bill, the furnace starts working again.

There was a bunch of water in the little fan enclosure. Not sure what the exact name of that part is but somehow the drain hose got plugged and it filled up with water. We got all the water out of there and it's working fine now.

The little fan is called a furnace exhaust fan. Glad to hear you have heat, I am sure your wife doesn't want you trying to snuggle up against her every night because you are cold.

Being an industrial furnace guy (think furnaces bigger than your house), I agree with the assessment above.

Look inside, if when it is going "on and off" you actually have flame, then it is almost certain to be your flame rod (flame detector). They are cheap and easy to replace, just get the exact same model number as different models have different lengths of rod (the end of the rod has to be directly in the normal flame or it doesn't work.

When you pull it out it might just be "dirty" with some carbon buildup or a white corrosion. If that is the case then it can be cleaned with steel wool or something pretty abrasive (sometimes I would use contact/electrical cleaner, a solvent after the steal wool) and reinstalled. The buildup can sometimes make contact between the two "sides" of the flame rod and case it to short out shutting off the gas valve.

The only other option off the top of my head is that you could have a clog in your pressure switch line. Its a small rubber tube connecting your fan to a little device (called a pressure switch). The switch is just proving that your fan is on before the ignition sequence is allowed to go.

If the tube is clogged, the switch could get varying readings which would trip and untrip the switch. If the switch thinks the blower is off then it will shut off the gas valve.

Do you have a "drip leg" or "sediment trap" in the gas piping going to the furnace? Basically just what would look like an extra piece of pipe going down by itself and then capped off?

That is typically used to let any water condensation or dirt in the gas line to "fall out" by gravity before it gets to your gas valve.

You might want to open that up and clean it out if you have one before you have a similar problem in your gas valve.

Damn it dlazz. I just spent 2 minutes reading most of this thread.

My job is done here.

But it did remind me that my AC condenser/fan isn't kicking on.

Now if you she can also hook up with the car repair guy you wont have many worries at all.
