  If your Emerson Air Conditioner isn't cooling, one potential cause is a low refrigerant charge, which you can check with gauges. Another reason could be that the compressor contactor isn't pulling in. In that case, check the voltage at the contactor; if there's no voltage, refer to the wiring diagram to find the voltage loss and check the enthalpy sensor for full CCW or D setting. Finally, ensure the thermostat is outputting correctly; it should have voltage output to the Y terminal during cooling.

  If the heat isn't working on your Emerson Air Conditioner, first check the thermostat for proper output to the W terminal. Another potential cause is a blown fusible link, which you should check for an open and replace if necessary. Finally, a bad contactor could also be the culprit; check it for an open and replace it if needed.

Why does my Emerson Liebert InteleCool 2 cycle on the high-pressure switch?

  If your Emerson Air Conditioner is cycling on the high-pressure switch, it could be due to a loss or restriction of airflow. Check the condenser blower assembly for proper operation and inspect for a dirty coil or inlet grille restriction. It might also be due to a defective fan cycling control switch. The switch should make @ 240 PSIG ?10 (1655 kPa ±68.9). Check settings on adjustable switch when supplied.

  Justin FriedmanAug 23, 2025
  If your Emerson Air Conditioner won't start, there might be a few reasons. First, ensure the unit is receiving power by checking the voltage to the input circuit breaker. Another possibility is an open control voltage circuit breaker, in which case you should locate the short and reset the breaker. Lastly, the thermostat might be defective or shutting off the unit; check the thermostat's operation.
