What does Kaeser warning 0060 W (start temperature low) mean?
Short answer: Machine too cold to start. If your Kaeser Sigma Control 2 is showing 0060 W — Start temperature ↓, the controller has logged a specific, documented condition. This page covers what it means, what causes it, what you can safely fix yourself, and when — and why — it takes a technician.
What exactly is the machine telling you?
The airend temperature is below 35°F (about +2°C), too low for a normal start. There is also a stronger 0059 W "Start temperature ↓↓" warning below 14°F.
Which machines show this?
the wide range of current-generation Kaeser rotary screw compressors — ASD, BSD, CSD, DSD, ESD and related series — built since roughly 2011 with the Sigma Control 2, the industrial-PC controller with a text display and RFID access. It reports faults as a four-digit number plus a letter: 'A' messages are alarms that shut the machine down, 'W' messages are warnings or service reminders it keeps running through, with arrows marking whether the value went over or under its limit — so 0015 A is the airend-overheat shutdown while 0013 W just asks for an air filter. Practical tip: the same subsystem often has a W and an A code (0004 W before 0022 A on the separator); acting on the W message is how you avoid the A shutdown.
What causes it?
- Airend below 35°F (about +2°C) — too cold for a normal start by design
- Compressor room unheated in cold weather (a stronger 0059 W warning exists below 14°F)
Can you fix it yourself?
Yes — warm the room to within limits; do not force repeated start attempts on a cold machine.
Step by step — what to try, in order:
- Raise the compressor room temperature — the ambient must be brought within specified limits.
- Do not force repeated start attempts while the unit is below the minimum temperature.
When do you need a technician — and why?
If the space cannot be kept warm enough, the fix is a machine-mounted heating option specified through Kaeser service, not repeated cold starts that punish the airend.
If it does come to a service call and you're in Nashville, TN or Birmingham, AL, we maintain independently compiled lists of local companies that service industrial air compressors — real businesses with verified contact information, none of whom paid to be listed.
