Finding Solutions for High and Low Temperature Test Chamber Failures

A high and low temperature test chamber is a relatively complex testing device. If a malfunction occurs, it should be analyzed and addressed based on the specific situation. Below are some common failures of high and low temperature test chambers and their corresponding solutions:

1. The test chamber cannot heat up: This may be caused by a heating system failure, power supply issues, or damaged control circuits. In this case, check whether components such as the heater, fuse, relay, and temperature controller are functioning properly. If a fault is found, replace or repair the component promptly.

2. The test chamber cannot cool down: This may be due to a refrigeration system failure, clogged condenser, or refrigerant leakage. Check whether components such as the refrigeration compressor, condenser, and expansion valve are functioning properly. If a fault is found, replace or repair the component promptly.
   

3. Unstable temperature and humidity control in the test chamber: This may be caused by environmental temperature fluctuations, fan failure, or humidity sensor malfunction. Check whether the ambient temperature of the test chamber, the fan, and the humidity sensor are functioning properly. If a fault is found, replace or repair the component promptly.

4. Uneven temperature and humidity distribution inside the test chamber: This may be due to an unreasonable internal structure of the test chamber, fan failure, or improper placement of the humidity sensor. Readjust the internal structure of the test chamber and check whether the fan and humidity sensor are positioned correctly. If necessary, increase or decrease the number of fans or relocate/replace the humidity sensor.

5. Excessive noise from the test chamber: This may be caused by a malfunction in the refrigeration compressor, fan, or transmission components. Check whether the transmission components, refrigeration compressor, and fan inside the test chamber are functioning properly. If a fault is found, repair or replace the component promptly.

The above points outline solutions for high and low temperature test chamber failures based on specific situations. If you are unable to resolve the issue yourself, it is recommended to seek assistance from professional technicians for repair and maintenance.
