Model # XC21-036-230-06 Serial # 5811F14762 Completed a preventative maintenance on a Lennox air conditioner. Customer changed out 16x25x4 filer. When I arrived I took a split temperature and it was 21 that tells me the refrigerant levels are good. Then I made sure the condensate pump is working. Then I went out and performed a amperage readings on the condenser fan motor running at .98 amps and the compressor running at 9.2 amps both are operating properly. Then I tested the capacitor it is not in range, I did replace the Capacitor. System is tested and operating properly at this time.
