I went into diagnostics over the system and found that the contactor coil was shorted. I also found that the capacitor is very weak and out of spec. I brought this to the attention of the homeowner and made her a few repair options. I replaced the contactor and got the system up and running. I also had to replace the blown fuse in the furnace. The system started immediately and started to cool. System is in working order at completion of appointment.
