Title: Compressor Rattles Loudly When Shutting Off Post by: Cobrargc on February 09, 2008, 02:38:18 pm Hello Everone!
The Cavalier machine I gave to my church is working great. However when the compressor cycles off it shutters and rattles loudly. It may do this at the end of every 3rd cooling cycle. Something to be concerned with??

or it could be a broken internal snubber spring inside the compressor itself, these act like shock absorbers for the small piston pump inside the compressors housing, to absorb the torque (tendency to twist opposite of the motors rotation) of the electric motor that drives the compressor (internally) on startup & shut-down of the compressor. if it is a broken internal snubber spring, the compressor may sooner or later break the internal tubing connecting the copper lines to the compressor/pump itself, & then you'll have a unit that will run , but it won't cool because it will be unable to circulate the freon. |
