    This unit is a Wheatherking Air Handler Model #RCBA-37656. The system is still cooling the house but the noise keeps us up at night. It sound like sopmeone is jumpimng up and down in my attic. It is not something I wish to live with.

  • psilverma264 Aug 05, 2010

    The noise seems to occur on the shut down, not the start up. It is a long whistle followed by a loud thump, thump, thump, thump.

    Anybody have any ideas?

    I think this is probably the best explanation. But now, what do I do about it? What do I fix or replace to end the noise?

Hi,
Is this a heat pump??? Sounds like it could be the reversing valve....
If it has done it for that long and still works...I would not worry about it... there probably is nothing you can do short of a major fix anyway...

    It is not a heat pump. It is a Weatherking air handler. The noise keeps us up at night. I do not want to ignore it. I have had several contractors look at it and they cannot figure it out. In the meantime, my warranty has probably expired.

    Thanks for clearing up that it is at the air handler....many people fail to provide adequate info to really diagnose the problem...we end up guessing as I did...and then I get a two thumb rating because I guessed...so now I will try again based on the extra info that you gave...

    It seems funny that you would expect someone sitting behind a computer, miles away to correctly diagnose something that people at the site could not correctly diagnose...but here goes...

    The squealing is most likely refrigerant bleeding through the relief tube of the exspansion valve, but maybe not if the unit has an orfice...then it could be refrigerant bleeding through the orfice....the thumping could be ductwork and unrelated to the squealing...or it could also be related to the refrigerant and liquid in the lines causing a thump...

    without actually observing what is happening anything anyone tells you from a computer is pure conjecture...

    The first thing I would do is try to observe the unit when it shuts down and find out what is loose and banging...then secure that part... probably a refrigerant line or somewhere in the ductwork...

    Then I would have the refrigerant system pumped down and completely vacumed... this removes any air or impurities from the system... then recharge the system with fresh virgin refrigerant...probably R-22....

    This should eliminate your problems...

The squealing noise is from bad fan bearing.and the banging noise is from fan .the faulty bearing is making the fan movement improper causing this noise.Remove and replace the fan also check the fan motor and motor bearing.your power to the outdoor unit should be at your circuit panel ,it may not be marked, but it is a double pole breaker. you should also have an outdoor disconnect service switch next to the outdoor unit to kill power to the unit.As far as outside fan turns and makes a loud noise, you may have a bad outdoor motor.The compressor can not run unless that motor is turning ( they work together ). Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

If this would have been a bearing or mechanical problem, it would have gotten worse years ago, so I really don't think it's a serious issue. What I think is that a movable duct door, or possibly damaged or loose ducting is making sounds everytime the blower comes on, and those are the noises you've been hearing. You would have to get into the ducting system to check it, but it's not clear to me whether it's worth the effort. I vaguely remember having this same issue at a place I lived many years ago, and it was always the same, and never got worse. If you're worried about it, a good service person would pretty much know what's going on by listening to it, if they were experienced in your brand, but you'd have to pay to get their opinion.
Here is a report of this problem (same as yours) on a web answer:

Good luck, hope this helps, and thanks for using FixYa!

    I dont think it is the expanding metal or even a duct door that is causing this noise. I have heard that kind of noise before in old systems. This happens mostly on the shut down not the sart up. It is a long whistle followed by thump, thump, thump, thump, thump, thump, thump, thump.

    Any additonal thoughts?

I just had a new COZY L.P. GAS CDV336C installed... Every few minutes it makes a loud bang noise...It then makes pinging noises that gradually fade out...This happens 2-4 times every hour. The bang is loud...


Hi Loretta:
I'd contact the installer. This sounds as if there may be a slow leak. When the gas concentration is high enough it will ignite which would be the bang that you hear. The popping sound could be the flame at the leak source point re-igniting for a few times.
DEFINITELY CONTACT YOUR INSTALLER OR GAS INSPECTOR. THIS IS A SAFETY HAZARD.

Loud noise burning smell


Most likely a belt problem or a worn out tensioner. You left off the year, make, model and engine so it's a guessing gamet. Read this post on how to track down the source of noise

could be the power steering pump itself. If it has a bad bearing it will do that. Especially when you turn it makes the steering pump work a lot harder.
