    any furnace repair men?

    So 2009 seems to only be getting worse for me, i can't wait till this year is over...

    just a bit ago i noticed that my furnace had been running for a long time and so i went and looked at it and the fan/blower is working, but the gas isn't kicking on. So it's only blowing cool air. Also, there's a water gurgling sound coming from the fan/blower thing. i have no idea at all and i know i'll have to call someone, but i figured i'd post on here just in case.

    i'm SO glad this happened before a holiday when i can't get anyone here AND it's getting colder out

    here's a pic the guts.

    I'm not the furnace guy you're looking for, but is the pilot lit? If not, are you smelling gas in the immediate area while the fan is blowing? Just trying to get an idea where you have started.

    I've lost my thermocouple before, and the furnace didn't know when to kick the burner on.

    Re: any furnace repair men?

    Look at the burners and you will notice an L shaped wire on the back side of either the far laft or far right burner. Take some sandpaper and(delicately)clean this sensor. It controls the flame somehow. I watched a furnace guy do it at my old house $100 so when it happened at my new house I cleaned it myself and the furnace runs fine. If you have a high efficiency the sensor may not exist and it will cost you more to fix. This is also a good time to vacuum out the furnace as dust is what causes the sensor to become clogged.

    Re: any furnace repair men?

    ok thx guys. the pilot doesn't seem to be out because i turned it off for about 30 mins or so and turned it back on. the burners kicked in and then after about 15 secs they shut off and there's no fan isn't kicking on. so it's just running but no air is flowing and the burners are off.

    Re: any furnace repair men?

    Its prob not the flame sensor due to the gurgling noise you are hearing but should be cleaned once a year. The gurgling noise is coming from the condensation in the lower heat exchanger. Check your vinyl hoses for a restriction. Pull all of your black vinyl hoses for water in them especially by the small combustion fan. Make sure it is draining properly. Could be filled with water. All of this can cause a pressure switch not pass power. Post your findings.

    Re: any furnace repair men?

    well it seems that the problem is the main fan/blower that blows air through the vents. it won't turn on unless i change the switch on the thermostate from auto to "on." so i guess i should have heat but i'll just have to keep turning the fan on. the only problem is that the furnace keeps running.

    thx for the advice guys.

    Re: any furnace repair men?

    I would also say the flame sensor. I go through that same senario every year or two where the burner will try to fire and kick off. The flame sensor is dirty. Its a built in safety for the furnace. If it does not sense the flame it will not allow the burner to fire. The fan will continue to run if the burner fires or not.

    PM me for a guy that is a lot cheaper than when you call a company. He used to work for a company doing it and now he's on his own.

    Re: any furnace repair men?

    Definitely need the flame sensor cleaned. Happens about every 3yrs or so on my furnace. Will work fine after you get it cleaned.

    I agree on the flame sensor. Clean it and try again.

    This. It is very simple. I had to do it a few weeks ago.

    Re: any furnace repair men?

    I also used to clean my flame sensor every couple of months when I had my old furnace. However, instead of sandpaper, I used a piece of steel wool. It was very easy to do and I avoided a $100 service call each time.

    Re: any furnace repair men?

    thx for the help guys. i'll see if i can figure out how to clean te flame sensor.

    i turned the furnace off before i went to bed lastnight just incase. Glad we got new windows this summer. anyway, i turned it back on and it fired right up and the burners kicked in and the fan started up. i'm still going to look at cleaning the flame sensor and have someone come look at it i think.

    I agree. The gurgling is a dead giveaway. Doesn't take much moisture to screw things up. Fairly typical thing on these newer H.E. furnaces. Side vent pipe may have sagged causing a water dam.


    Walking on water is easy. Just do it in December when it's frozen.
