If the cooling capacity of the plant has reduced and it is not being able to maintain the provision room or cargo hold temperature, following may be the causes :

Reasons Solutions
Inadequate refrigeration. Charge refrigerant in the circuit.
Insufficient or damaged insulation in the room. Check and renew the insulation.
Room or hold is over packed. Ensure that the room is not filled above its capacity.
Malfunctioning solenoid or TEV. Check the functioning of these valves and renew if not functioning properly.
Poor thermostat location that senses cold temperatures. Place the sensor of the TEV in proper location i.e discharge of the evaporator.
 Room door is kept open. Ensure to close the door while exiting the provision room.
