What to do if the compressor fails to start on my Ingersoll-Rand American Standard 4A7L6018A1000A Air Conditioner?

If the compressor on your Ingersoll-Rand Air Conditioner fails to start, begin by checking the contactor. If it still doesn't start, wait three minutes before rechecking the contactor, ensuring you have 24 volts AC across the contactor coil. If problems persist, the room thermostat may need replacement. Also, inspect the low voltage transformer and control fuse. Repair or replace the transformer or fuse if necessary. Finally, investigate the cause of the failure, looking for potential shorts in the connecting wiring.
