What to do if there is a High Discharge Temperature Fault in my Danfoss Turbocor TT?
- P
  pbakerAug 16, 2025
  A high discharge temperature fault in the Danfoss Air Compressor often suggests insufficient charge (low gas), increased condenser temperature, a check valve that hasn't opened, or the compressor running in surge condition for too long. To address this, check the chiller gas charge, the conditions of the air/water entering the condenser, and the operational settings. Also, make sure the discharge pressure/temperature sensor is working correctly and that the check valve opens during compressor operation.

What to do if there is a Low Suction Pressure Fault in my Danfoss Turbocor TT Air Compressor?
- M
  Mary ReidAug 19, 2025
  A Low Suction Pressure Fault in your Danfoss Air Compressor suggests there may be insufficient charge, insufficient system load, or a sudden drop in evaporator entering air/water temperature or flow. You should check the charge, system load, and entering air/water conditions to resolve this issue.

What to do if I see a High Inverter Temperature Fault on my Danfoss Air Compressor?
- N
  Nicholas BlairAug 22, 2025
  A High Inverter Temperature Fault in your Danfoss Air Compressor indicates that the inverter cooling is not sufficient. Ensure that the liquid motor-cooling line has enough liquid supply and is not blocked. To prevent Inverter failure, avoid running the compressor for long periods at a pressure ratio less than 1.5. If the fault occurs three times in 30 minutes, a Lock-Out Fault will occur. In this case, allow the measured Inverter temperature to drop below the Maximum Drive Startup Temperature before attempting a restart.

  A High Discharge Pressure Fault in your Danfoss Air Compressor suggests that the condenser may be faulty or there's insufficient air/water flow. You should check the condenser and air/water flow. Also review the fault log for the actual discharge pressure and other conditions recorded at the time of the fault.

What causes a 3-Phase Over-Current Fault in a Danfoss Air Compressor?
- B
  brandydennisAug 28, 2025
  A 3-Phase Over-Current Fault in your Danfoss Air Compressor means the compressor is drawing more current than the 3-Phase Current Fault Limit. Review the fault log for the recorded 3-Phase Current level, demand, entering air/water temperature (if available), and other conditions recorded at the time of the fault. This fault can also be related to a start speed or minimum pressure ratio that is set too high at start-up, a power control integral gain that is too high, or a sudden increase in load/demand or system changes.

  Lisa BrooksAug 31, 2025
  A High Cavity Temperature Fault in your Danfoss Air Compressor indicates that the motor cooling is insufficient. Ensure the liquid motor-cooling line has sufficient liquid supply and is not blocked. To prevent shaft demagnetization or Back EMF is low faults, avoid running the compressor for long periods at a pressure ratio less than 1.5.

What causes a High Pressure Ratio Fault in my Danfoss Turbocor TT Air Compressor?
- R
  Rhonda HowardSep 3, 2025
  A High Pressure Ratio Fault in your Danfoss Air Compressor suggests the condenser pressure is high, there is not enough load on the evaporator, or there is insufficient water/air flow in either the condenser or evaporator. Check the electronic expansion valve (EXV) operation, condenser and evaporator loads, and water/air flow.

What does a Low Leaving Fluid Temperature Fault mean on my Danfoss Turbocor TT Air Compressor?
- B

What does a Sensor Fault mean on my Danfoss Turbocor TT?
- D
  Dennis DeanSep 12, 2025
  A Sensor Fault in your Danfoss Air Compressor may be caused by values out of the specified ranges. Review the fault log for any such indications recorded at the time of the fault. Verify the questionable sensor and related connections to check for failure. Also, verify the suction pressure/temperature sensor.
