What must be done to reset the reefers?

To reset the reefers, it's essential to follow a specific procedure that often involves addressing the high pressure switch. When a reefer unit experiences a critical situation, such as a high pressure fault, the system will shut down to prevent damage. The correct approach is to reset the high pressure switch, start the unit again, and potentially bypass any safety features if necessary, depending on the circumstances.

This procedure is crucial because by resetting the high pressure switch, you are effectively reinitializing the unit and allowing it to operate safely once conditions are deemed normal. Other factors, such as adjusting the thermostat or checking fuel levels, play important roles in overall reefer performance but do not directly pertain to the reset process. Inspecting the vent system is also a valid maintenance task but does not specifically relate to the immediate need for resetting the units in this context.
