Manufacturer Goodman Model # GSX160361 Serial # 2106636789 Customer called about here air conditioner not working. The Honeywell T4 that we installed was on a program setting, I turned that function off and the system started working. Then I performed a preventative maintenance the temperature split was 19. Customer changed 16x25x1 filter. Also, made sure the condensate pump is working. Then I went outside and performed a amperage readings on condenser fan motor and compressor both are operating properly. System is 2 years old and operating properly.
