Furnace banging (50)
mylifewithuSpringfield, Missouri USA174 Threads 23,670 Postskitty01: Thanks everyone, just wanted to know if anyone else has a furnace that shakes the house and blows open the basement door.
If it's blowing open the basement door , I would talk to a furnce company that does repairs and talk to them about what might be wrong with it. That sounds wrong. I have had lots of noise from furnaces heating up and cooling down, but not blowing open doors.

When the bang comes the floor even shakes. Friends were over and thought maybe it was a ghost opening the doors.

It could be the sudden heat just popping the duct, because the duct is cold. ( a good example of this is when you are cooking in the oven, YOU put a thin pan in there and when it reaches a certain temp. it pops......but it could also be that there is way too much gas let out before the igniter kicks on( could be your igniter is going bad so it is slow or a leak in the gas valve or a sensor which controls either the gas or igniter...JMO
But it could like I said, just be what your landlord said... I'm not there but I would get a second opinion. Just to be on the safe side...
Good luck..

This happens when the pilot lights across before the fan comes on to blow the heat up. So thinking now how can the heat be doing it when it is before that.

You see Kitty,there's no noise in your basement,that's me moaning at the top of my lungs.

your ducts are expanding as they heat up thermal deformation.
you need to accomodate fot the expansion

it's loud because it's attached to the downstairs ceiling joists which your floor rests on
The sound travels throughout the duct system to amplify the sound

I just read this... Hun, Call someone to come check it out seriously
It sounds like you way too much gas released before the igniter is kicking in... if you don't fix it the "booms" will only get bigger..

I work on HVAV, plumbing and Maint for a living.
If it is actually opening a doop,
either their is not enough makeup air, the purge isn't working or..the gas/air mix is way too rich.(can tell the later if the flame is burning all blue or all yellow) if so.. bad air mix.
still can't say without actually seeing it.
too many variables.

true,
and not to make light of your situation hun, but some people are more nervous and/or high strung then others. So Some people without meaning too over exagerate things, you said BLOWS the door open, so at first I think bam!! but it could mean gently blows the door, like what a screendoor might do to the inside door if the door is not latched. which only has to do with pressure... SO I say get a second opinion then go from there...

kitty01: I have phoned the landlord and they will do nothing, says it is just the cold air, and not to worry.
Burners are in need of cleaning and also just open it up when its off and vaccum out stuff thats lying there loose.
Change the filters.They are cheap.
Thermocouple is bad or going bad.(jmho not a professional)
This is somewhat of a timing metering mechanism for fuel and ignition.
These are cheap to replace,but costly if someone does it.$125 or so .
Check those kitty.

Mine doesn't at all! I just suddenly hear air coming out of the vents. It's also a gas furnace.

Thermocouple= only is a flame sensor for the pilot.
if pilot is lit it allows the burner to get fuel and light, if bad or no pilot flame.. it just wont let the gas come on to the burner.
saying... if the pilot won't light, or is lit but the main burner wont engage... then the thermocouple is bad.
So K, have you had it looked at yet, if so...what was the problem?

Still say either the purge motor is bad or most likely the air gas mixture is too rich, just a simple adjustment,

just though of one more thing,, the pilot flame may also need to be adjusted higher, easily done.
if burning too low,, it will allow the burner chamber to fill with more gas than normal before igniting,

Hi Rasgumby.She said she has been in there for three years.
Would be about time to change this anyway.
DEFINATELY flame quality ,is a good place to start thought process.
Yellow =bad Blue=good.
1)clean things up in there
2)change the filter
Try those two first.Simple to do yourself.
Damn those cheap landlords.
Bet ya,i'm right Rasgumby.Race ya overthere. j/k.
Hey,hurry back here Kitty.We'll walk ya thru this.
