Source:LINPIN Time:2025-04-16 Category:Industry News

When a temperature cycling test chamber malfunctions, how should you troubleshoot it? Have you identified the correct diagnostic approach? Mastering the right methods can help quickly locate the issue and restore functionality more efficiently.

Common Faults and Solutions:
Chamber Does Not Start When Powered On:

Check if the main circuit breaker is engaged or damaged. Replace it if necessary.
Overheating Issue:

Possible cause: Solid-state relay is short-circuited.
Solution: Replace the relay and check if the control parameters are malfunctioning. Adjust the settings if needed.

Slow Heating:

Possible causes:
Fan not working properly → Inspect the fan.
Chamber door not closed tightly → Ensure proper sealing.
Excessive load → Reduce the load.
No Heating at All:

Possible causes:
Solid-state relay is open-circuit → Replace the relay.
Heating element is damaged → Replace the heating tube.
No Cooling:

Possible causes:
Solid-state relay is short-circuited → Replace the relay.
Insufficient refrigerant → Replenish the refrigerant.
Temperature Fluctuation (Unstable Control):

Possible causes:
PID parameters are misconfigured → Recalibrate the PID settings.
Temperature sensor failure → Replace the sensor.
Overpressure Alarm:

Possible causes:
High ambient temperature → Lower the surrounding temperature or replace the axial fan.
Excess refrigerant → Release some refrigerant.
Solution: Press the reset button and check the system.
Overload Protection Triggered:

Possible causes:
Faulty overload protector → Replace it.
Excessive current → Adjust the overload range and press the thermal overload reset button.
Also, inspect the refrigeration circuit for issues.
These are some of the key troubleshooting methods for temperature cycling test chambers. If the problem persists after applying these solutions, contact after-sales support for professional assistance.
