Thermo King Fault Codes
In this table you will find the trouble codes and alarms of the controllers MP-IV, MULTI-TEMP, MP-IV, MP-V, MP-VI, TG-VI, SR-2 and SR-3. Codes recorded by the controller depend on its type, software version, installation model and optional equipment. You will find more detailed information in the table of alarm codes at the facility or in the appropriate operating and diagnostic instructions for the controller.
Note. If the alarm code is detected during the installation self-diagnosis, then its number will be preceded by a dash (-).
