Why is there no cold air blowing on my Thermo King TS 600?

Why does cold air airflow disappear on Thermo King TS 600?

Roof-mounted refrigeration units Thermo King TS 600 are widely used in cargo transportation due to their reliability. However, even this equipment can develop faults over time. One of the most common problems is the absence or weak airflow of cold air, while the unit itself may continue operating.

In winter conditions, such malfunctions are especially dangerous, as they can lead to cargo spoilage and urgent, costly repairs.

Main reasons for lack of cold airflow

In practice, the problem is most often associated with the following components:

• pilot solenoid malfunction;
• sticking air system valves;
• contamination or icing of air ducts;
• control system failures;
• consequences of operation in severe frost.

One of the key and underestimated causes is the pilot solenoid.

What is a pilot solenoid and why is it needed?

The pilot solenoid in the Thermo King TS 600 system controls air supply and proper valve operation. It is responsible for correct airflow distribution and participation in cooling mode regulation.

If it malfunctions:

• cold may be produced but not delivered into the cargo compartment;
• the system operates unstably;
• errors and reduced cooling efficiency may occur.

It is important to understand: removing the pilot solenoid or “disabling it permanently” is not allowed — this will lead to incorrect operation of the entire refrigeration unit.

Why it is important to fix the malfunction immediately

Operating a refrigerator with disrupted airflow may lead to:

• compressor overload;
• failure of valves and sensors;
• costly major repairs;
• downtime and loss of orders.

Timely contact with a service center allows you to limit repairs to targeted repairs, rather than replacing expensive components.
