In Wickenburg, near West Wickenburg Way and North Vulture Mine Road performing a diagnostic on a commercial Carrier package heat pump. Upon arrival, found thermostat to be blank due to blown fuse; capacitor blown apart and motor grounded out. Installed new 1/4 Horse 1075 460 volt motor and new 7.5/440 run capacitor with new fuse, and system is now running properly and within manufacturer specifications.
