  If the compressor on your Galletti Air Conditioner isn't starting, it could be due to: * Compressor burnout or seizure: The solution is to replace the compressor. * Compressor contactor de-energized: Check the voltage at both ends of the compressor contactor coil and check the coil's continuity. * Open power circuit: Find the cause that tripped the protection.
