Quick answers
What this page covers
PAL is an indication that should not be assessed in isolation. The unit type, operating condition, temperature history, outside temperature and circumstances in which the fault appears are important.
What operators should record
The code alone is not enough for an initial assessment. The circumstances in which it appears and whether refrigeration capacity is reduced at the same time are decisive.
- Note the time and operating mode when the fault occurs.
- Record temperature history and outside temperature.
- Photograph the controller display.
- Add the refrigeration unit type and serial number.
Why professional inspection makes sense
An error code can point to different technical circumstances. Without measurements and professional inspection, there is a risk of treating symptoms rather than causes.
- Pressure, fan, sensor and power supply conditions can be interrelated.
- Replacing a part without a diagnosis does not always resolve the cause.
- A traceable diagnosis is especially important for warranty and goodwill cases.

Frequently asked questions
Frequently asked questions on this topic
What does the PAL error code mean?
Treat the code as a technical indication to be assessed alongside operating conditions, temperature history, unit type and serial number. Establishing a reliable cause requires professional inspection.
Can I continue driving with a PAL error code?
This depends on the goods, temperature history and system behaviour. If the cold chain is at risk or the system repeatedly shuts down, secure the operation and report a service case.
What information is most helpful for PAL?
Useful information includes a photo of the controller, rating plate, serial number, unit type, current temperatures, outside temperature, operating mode and a brief description of when the code appears.
