Window AC - "Squeak" Noise when compressor turns off
Hello all,
A friend of mine directed me to this forum for some advice. I just purchased a LG LWHD8000R Window air conditioner last week, and I noticed that occasionally the unit makes a "squeak" or almost whistling noise when the compressor turns off. It almost sounds like pressurized or compressed air being released. It only does this very briefly and only after the compressor turns off during normal use. I picked up a second unit of the same model, tested it, and noticed that it does the same thing. Is this normal or something I should be concerned about? The unit is cooling very well - for now, at least. As the unit is quite new, I can still return it easily if necessary. Thanks.
John

Lg squeak noise, hmm... it's probably the little mouse on his bicycle out of breath, you should...........(I appologise for that. It was just tooo tempting).
If it's like a hissing sound it will just be pressure equalizing between the high and low pressure sides of the system across the expansion device when the compressor shuts down. Nothing to worry about.Last edited by expat; 30-08-2007 at 01:24 PM. Reason: spelling
