If the temp is cool it will only blow so cold then the compressor shuts off Drove me nuts when I added the freon last week on the raffle car by the way the compressor on the raffle car was replaced Old one developed a front seal leak so this one works real good and is about three to four degrees cooler that the old one ever was do it above 50 degrees and preferably above 60 degrees Took me an extra half hour to make sure it was working right Ken PS we do offer air conditioning service at my warehouse appointment necessary both 134b and R12 -----Original Message----- From: David Teitelbaum <jtrealty@xxxxxxxxxxxxx> Subject: [DML] Re: A/C cycle very short Depending on the temperatures that may be normal operation. Make sure the evaporator coil and condensor coil are clean. The way to change the cycle time is by the amount of refrigerent and adjusting the low pressure switch. Under normal operation the compressor is supposed to cycle.
