What to do if Ingersoll-Rand Air Compressor fails to start?
- C
  christycombsAug 14, 2025
  If your Ingersoll-Rand Air Compressor fails to start, there are several potential causes and solutions: * Check the fuses, transformers, and wiring connections to ensure that 110/120V control voltage is available. * Inspect the contactors in case of a "STARTER FAULT". * If there is an "EMERGENCY STOP" message, rotate the emergency stop button to disengage it and press the "SET" button twice. * If the message is "MAIN MTR OVER LD", manually reset the main overload relay and press the "SET" button twice. * For "PRES SENSOR FAIL", "TEMP SENSOR FAIL", or "NO CONTROL POWER" messages, check for a defective sensor, a bad sensor connection, or broken sensor wires.

Why does my Ingersoll-Rand Air Compressor shut down?
- V
  vhowellAug 18, 2025
  Your Ingersoll-Rand Air Compressor might shut down due to several reasons: * If there is a "HIGH AIREND TEMP." message, ensure the installation area has adequate ventilation. * For a "HIGH AIR PRESS." message, make sure the cooling fan is operating. If not, reset the circuit breaker inside the starter box. * If the message is "LOW SUMP PRESS.", check the coolant level and add coolant if needed. * In case of "PRES SENSOR FAIL" or "TEMP SENSOR FAIL", check for a defective sensor, a bad sensor connection, or broken sensor wires.
