What to do if Ingersoll-Rand Trane 4TWL6018A1000A compressor fails to start?

If the compressor fails to start, begin by waiting 3 minutes before checking the contactor. Next, verify that 24 volts AC is present across the contactor coil. If voltage is present at the contactor coil, replace the contactor. Also, check the low voltage transformer and control fuse. If the control transformer is functioning correctly, jumper the R to Y low voltage terminals at the contactor. If the thermostat energizes, replace the room thermostat. Finally, repair or replace the transformer or fuse, and investigate the cause for the failure, looking for potential shorts in the field wiring.
