Performed AC diagnostic on three-year-old Lenix condensing unit. Upon my diagnostic I found at the outdoor condensing unit have the fan running and not the compressor. Verified the secondary motor control was not bad in the compressor itself it failed. A compressor saver kit was added in the compressor then turned over and was pulling 10 Amps. Upon letting the system run for approximately 15 minutes I found that the R410a refrigerant pressure charge was very low. This is due to a leak somewhere within the refrigeration cycle. Leak dye was added along with 3 pounds refrigerant and a warranty compressor savor kit. Will follow up in about 30 days for a return visit on the Leak dye.
