Professional Temperature & Humidity Chamber Repair Service

In April 2026, the technical team of VintechME successfully received and resolved a malfunction case of a temperature and humidity test chamber at a customer’s factory in Bac Ninh. This is one of the common issues that directly affects the accuracy and reliability of environmental testing.

With extensive experience in maintenance and repair of environmental test chambers, VintechME always ensures fast response, effective troubleshooting, and cost optimization for customers.


Initial Issue Information

The customer reported that the test chamber displayed the following errors:

  • TEMP ERR (Temperature Error)
  • HUMI ERR (Humidity Error)

These errors caused unstable operation of the chamber, impacting testing schedules and product quality verification.


On-site Inspection and Assessment

Immediately after receiving the information, VintechME engineers arrived on-site to carry out a detailed system inspection.

Inspection results:

  • The condenser fan was found to be faulty
  • Without the fan, the condenser temperature increased significantly, causing the chamber to trigger an over-temperature alarm
  • This was the direct cause of the TEMP ERR and HUMI ERR errors

Repair Solution

After identifying the root cause, VintechME proposed and implemented the following solution:

  • Replace the faulty condenser fan with a new one
  • Inspect related systems:
    • Heater
    • Humidifier
    • Temperature and humidity sensors
  • Ensure the entire system operates synchronously after repair

Testing and Acceptance Process

After replacement:

  • Conducted trial runs under various temperature and humidity conditions
  • Verified system stability:
    • Temperature reached and maintained at setpoints
    • Humidity controlled accurately
  • No recurrence of TEMP ERR / HUMI ERR

The chamber was successfully accepted and handed over to the customer

Root Causes and Preventive Recommendations

Common Causes:

  • Continuous operation of the circulation fan without regular inspection and lubrication
  • Dust accumulation or harsh environments reducing fan lifespan, leading to eventual jamming

Recommendations from VintechME:

  • Perform periodic maintenance (every 3–6 months)
  • Regularly check fans and air circulation systems
  • Clean the chamber to prevent dust buildup and overload
