Jun 16, 2018 - The date of production/manufacture or age of LSB Industries, Inc. Brand HVAC equipment can be determined from the serial number located on. I would like a new air conditioner in a different model to replace the one we have. It's BEEN a lemon since the day we bought it. Friedrich AC Model #XQ08M10 Serial number AKLX00616.
I may be having a problem with my 2-yr old Friedrich 8000 btu thru-the-wall air conditioner: Briefly: After it has been operating for several hours, it begins to make a single ping sound repeated at about 60 sec intervals. After this continued for some time I pulled the AC plug. But the pings continued. Then, after about ten minutes, a few musical notes were heard and the pings stopped. Can you tell me what's going on and whether this is normal. Or is it a signal that the filter needs replacement or that some other maintenance is needed? (This is the first time this has happened in two years,) Bernard Kovit E-Mail: Bkovit7@optonline. Net Thank you.
