Out of service
- Alarm Code 10High Discharge PressureRefrigerant discharge pressure hit the safety limit. The unit protects itself by shutting down — which means the clock on your load has already started. Check airflow through the condenser first.
- Alarm Code 18High Engine Coolant TemperatureThe reefer's diesel engine is overheating. On most units this is a shutdown alarm, so treat it as a live load-temperature problem and not a maintenance item for next week.
