| It is a stored alarm. Indicates a condition that needs investigation but does not affect the unit’s operation. The alarm icon appears for 30 seconds when the unit is turned on and then disappears. | Requires verification. This alarm is a warning to take corrective action before an abnormal condition becomes serious. The alarm icon will appear and remain on. | Shutdown alarm indicating conditions that could damage the unit. The unit will shut down automatically, the alarm icon will appear, and the entire display will flash on and off. |
Thermo King Alarms:
This table shows the alarm codes for Thermo King equipment, possible causes of the issue, and some measures to take.
- Thermo King alarms are generated when the microprocessor detects an abnormal condition.
- Multiple Thermo King alarms can occur simultaneously.
- All generated alarms will be stored in memory until the operator clears them.
- Document all alarm cases and communicate them to the service technician.
- The Thermo King alarm table in Spanish shows all codes for all possible applications. Therefore, not all codes will be applicable to each individual unit.
- The operator can repair certain faults, while others can only be repaired by the Thermo King dealer.
- Some alarms may exist with Code 84.
- The alarm may disappear automatically if the condition does not repeat.
- Alarms that occur during a previous trip or a self-check of the unit will be preceded by a hyphen.
- Some alarms are automatically self-eliminated when the operating condition that caused the alarm returns to normal.
