What should be done if the cargo temperature is still high after the unit starts?

When the cargo temperature remains high despite the unit starting, checking for airflow obstructions and system performance issues is crucial. Proper airflow is essential for the effectiveness of temperature control in refrigeration systems. Obstructions in the airflow path can prevent the cold air from circulating properly around the cargo, leading to inadequate cooling.

Furthermore, assessing system performance is vital because it may reveal other underlying issues, such as low refrigerant levels, compressor malfunctions, or problems with the evaporator or condenser coils. These performance issues can adversely affect the unit's ability to cool, making it essential to conduct a thorough inspection rather than assuming the system is functioning correctly.

Addressing these aspects allows for a systematic approach to identifying and rectifying the issue, ensuring that the cargo temperature returns to the desired level effectively. Taking such proactive measures minimizes potential damage to the cargo and ensures compliance with temperature requirements for sensitive goods.
