HaoChen Team Professional Maintenance, Quality Assured!!! Professional maintenance for Temptronic TP04300A Thermal Airflow Shock Testing System. Common faults and their causes are analyzed as follows:

Fault Point: Unstable temperature control
Cause Analysis: Aging or calibration failure of temperature sensors causing feedback signal deviation; improper PID control parameter settings leading to inaccurate regulation of cooling/heating power.

Fault Point: Abnormal airflow circulation
Cause Analysis: Circulation fan failure (e.g., bearing wear or motor damage) resulting in insufficient airflow; deformed or blocked airflow baffles affecting uniformity.

Fault Point: Equipment fails to start
Cause Analysis: Power module failure or poor contact in the power supply circuit; control board program abnormalities or firmware damage; emergency stop button not reset triggering safety protection.

Fault Point: Refrigeration system failure
Cause Analysis: Compressor failure (e.g., refrigerant leakage or piston wear); poor condenser heat dissipation (e.g., dust accumulation or fan failure); blocked expansion valve disrupting refrigerant circulation.

Fault Point: Communication interface failure
Cause Analysis: Damaged RS232/GPIB interface circuits; incompatible communication protocol versions; loose cable connections or signal interference.

By understanding common faults of the equipment, you can better maintain and use it to ensure long-term stable operation. If you cannot resolve the issue, welcome to contact HaoChen!
