How to troubleshoot a LEYBOLD COOLPAK 6000-1 that won't run with no error message?

  If your LEYBOLD Air Compressor fails to run and shows no error message, check the power lead and plug, and ensure the line voltage matches the compressor unit's setting. Overloading can also cause this issue. Check for faults 2 to 5 in the manual. If the switch trips again after restarting, contact the Leybold Service Department. Also, inspect and replace any blown fuses (F1, F2, F3, F4, and F5) after identifying and resolving the cause of the overload.

What to do if my LEYBOLD Air Compressor shows a Phase/Fuse ERROR and fails to run?
- A

  If your LEYBOLD Air Compressor displays a Phase/Fuse ERROR message and won't run, it could be due to faulty wiring, electrical overload, or a defective cold head motor. Check the wiring connections and replace fuses if necessary. You may also need to reverse two phases of the power supply. Inspect the cold head motor and replace it if it is defective.

Why is the cold head performance declining on my LEYBOLD COOLPAK 6000-1 Air Compressor?
- C
  Cheryl SimmonsAug 26, 2025
  If the cold head performance of your LEYBOLD Air Compressor is declining, it could be due to a saturated adsorber, incorrect electrical connections, or a drop in helium pressure. Replace the adsorber, which should be done every 18,000 hours of operation. Check the electrical connections to ensure they are correct. Also, check the helium pressure and top up if necessary. If the issue occurs frequently, contact the Leybold Service Department.

What to do if my LEYBOLD COOLPAK 6000-1 Air Compressor shows a Pressure Alarm message and won't run?
- E
  Eric DavenportAug 28, 2025
  If your LEYBOLD Air Compressor displays a Pressure Alarm message and the pressure switch has tripped, there may be a leak in the helium circuit. Check the helium pressure and add helium if needed. If this happens often, contact the Leybold Service Department.

Why does my LEYBOLD COOLPAK 6000-1 show a Compressor fail message and not run?

  Gabriel LeeSep 1, 2025
  If your LEYBOLD Air Compressor displays a Compressor fail message, the thermal switch in the compressor capsule (Klixon) may have tripped because the compressor capsule is too hot, or the compressor motor is malfunctioning. Identify and address the cause of overheating, referring to malfunction 3 for possible causes and solutions. Allow the compressor capsule to cool down for 2-3 hours before restarting. If the problem persists, contact the Leybold Service Department.

Why does my LEYBOLD COOLPAK 6000-1 show a Phase/Fuse ERROR message but still run?
- J
  Jennifer HammondSep 3, 2025
  If your LEYBOLD Air Compressor displays a Phase/Fuse ERROR message but continues to run, the line voltage setting may be incorrect, the control voltage may be wrong due to a high load (like a malfunctioning cold head motor), or the mains voltage is near the specified limits (+10% or -10%). Set the compressor unit to the correct line voltage. Check the cold head and replace it if necessary. Measure the mains voltage to confirm it is within limits; if so, you can ignore the message.

What does it mean when my LEYBOLD Air Compressor displays a Locked rotor message?
- A
  alexandrahooverSep 6, 2025
  If your LEYBOLD Air Compressor displays a Locked rotor message and fails to run, the current drawn during startup was too high. Check the input power connections and try starting the compressor again. If the compressor fails to run with the same message three times and then displays 'OVERLOAD', contact the Leybold Service Department.

What does a MAINS LEVEL !!! message mean on my LEYBOLD Air Compressor?
- C
  christensencrystalSep 9, 2025
  If your LEYBOLD Air Compressor displays a MAINS LEVEL !!! message, the line voltage setting is likely incorrect, or fuse F2 has blown. If you press the SELECT button and see error message 5 ('Phase/fuse error'), ignore the MAINS LEVEL !!! message and address the malfunction as described in malfunction 5.

  Kimberly VargasSep 12, 2025
  If your LEYBOLD Air Compressor displays an OVERLOAD message, it means the compressor unit has failed three times to run with a Locked rotor message. Contact the Leybold Service Department.

Why does my LEYBOLD COOLPAK 6000-1 Air Compressor show a Helium temp.fail or Oil cct. fail message and not run?
- S
  Sandy GonzalezNov 21, 2025
  If your LEYBOLD Air Compressor displays a 'Helium temp.fail' or 'Oil cct. fail' message and fails to run, ensure there is sufficient water coolant supply with correct flowrate, inlet pressure, and that the inlet temperature is not too high. Also, verify that the water coolant lines are connected correctly and the heat exchanger is not congested. If the ambient temperature is too high, consider changing the installation site. For TSH1 reset, if available in your software version, you can try switching on the compressor using the ON button; it will run for 90 seconds if no other malfunction is detected. If the temperature does not fall below the switching point at TSH1 after 90 seconds, the compressor will shut down and display a 'He-Temp.90s fail' message. After that, you can only switch th...
