Trane AC-unit won’t start

A customer called Sunny Appliance Repair to get some help with his Trance AC that would not start. When one of our techs, Technician, checked the AC, he found out that the contactor was not getting the 24V. But when Technician tried pressing on the contactor with a screwdriver, it would start working. Next, he checked the thermostat, which was also not getting the 24V. Technician got on the attic to check the control board of the furnace. The 5A fuse was burned down, so he replaced it. When he turned on the furnace, the new fuse burned down right away. He checked the wires from the furnace to AC and determined that one of them was damaged. Once Technician repaired the damage, he went back and put the furnace together. The issue was fixed, and the Trance AC was blowing cold air again, which was a great relief for the customer on an extremely hot day.
