Reasons Why the Refrigeration Unit of a Constant Temperature and Humidity Test Chamber Fails to Operate

Release time:2025-04-18

We know that the refrigeration unit is the "heart" of a constant temperature and humidity test chamber—its most critical component. Only by ensuring the proper operation of the refrigeration unit can the chamber successfully achieve cooling and reach the preset low temperatures. The quality of the equipment depends heavily on a high-performance refrigeration system. So, what causes the refrigeration unit of a constant temperature and humidity test chamber to fail?

Constant Temperature and Humidity Test Chamber

Based on years of production experience, Yashilin provides a step-by-step troubleshooting guide:

  1. Check for poor contact between the plug and socket—if found, reconnect securely.
  2. Inspect the socket fuse to see if it has blown.
  3. Use a voltmeter to measure the voltage—low voltage may cause insufficient power supply.
  4. Verify if the temperature controller's adjustment knob is functioning.
  5. Check whether the overload relay is burnt out.
  6. Examine if the motor is damaged.

Once again, we remind users: When purchasing a vertical constant temperature and humidity test chamber, do not focus solely on price comparisons. Instead, carefully evaluate the manufacturer’s technical expertise, production capabilities, material quality, and overall reliability to ensure long-term performance and durability.

Recommendation
walk-in test chambers allow enterprises to perform various environmental tests, such as temperature, humidity, and light exposure, to simulate how products function under different conditions.
To ensure that products can maintain superior performance under extreme conditions, we offer high-performance dust test chambers to help enterprises enhance product quality and meet market demands.
Among them, NSS, AASS, and CASS are three common salt spray test methods. Below, we explain their differences and respective applications.
Programmable constant temperature and humidity test chambers are devices used to test and evaluate product performance under different temperature and humidity conditions.
