How to Deal with the Problems That the Constant Temperature and Humidity Chamber Can't Turn On?

The constant temperature and humidity chamber is usually called high and low temperature alternate humidity and heat test chamber, high and low temperature test chamber, high and low temperature humidity and heat test chamber, etc. It is generally suitable for quality inspection of mobile phones, electronics, electrical appliances, communications, instruments, vehicles, plastic products, metal, food, chemical, medical, building materials, aerospace and other products.


The constant temperature and humidity test chamber is a kind of high-end precision equipment, and damage to one of the components may cause the test chamber to fail to start and operate normally. Our experience in research and maintenance for many years has enabled us to sum up the maintenance plan of the fault, and we hope our method can help you.


Troubleshooting and solutions when the constant temperature and humidity chamber cannot be started normally:


1. Whether the connection of the constant temperature and humidity chamber is in good contact: reconnect it;


2. Whether the contact of the master switch of the constant temperature and humidity chamber is in good condition/whether it is burnt or damaged: repair/replace;


3. Whether the contactor or relay of the constant temperature and humidity chamber is in good contact/whether it is burnt or damaged; whether the over-temperature setting of the instrument is correct/whether it is burnt or damaged: reset/replace;


4. Whether the phase sequence connection of the power supply line (phase sequence relay) of the constant temperature and humidity chamber is correct/whether it is burnt or damaged: reconnect/replace;


5. Whether the pressure adjustment of the pressure controller of the constant temperature and humidity chamber is correct/burned and damaged: readjust/replace;


6. Whether the non-heating connection of the constant temperature and humidity chamber is in good contact: reconnect it;


7. Whether the instrument display of the constant temperature and humidity chamber is normal/whether there is output: repair/replace;


8. Whether the instrument setting of the constant temperature and humidity chamber is correct: reset it;


9. Whether the blast switch of the constant temperature and humidity chamber is turned on/whether it is burnt or damaged/whether the contactor is connected or burned out: re-open/replace;


10. Whether the heating switch of the constant temperature and humidity chamber is on/whether the contact is good/whether it is burnt or damaged: open the switch/repair/replace;


11. Whether the actuators (contactors, relays, silicon controlled, solid-state relays) of the constant temperature and humidity chamber have output: replace;


12. Whether the executive elements (heating tube, heating wire) of the constant temperature and humidity chamber are burnt and damaged: replace;


13. Whether the control of the controller, regulator and electric contact thermometer of the constant temperature and humidity chamber is in good condition/whether it is burnt or damaged: repair/replace;


14. Whether the heating of the constant temperature and humidity chamber is not controlled by the instrument display/whether control is normal: repair/replace;


15. Whether the instrument setting of the constant temperature and humidity chamber is correct/whether it is manual output: reset it;


16. Whether the actuator contactor and relay contact of the constant temperature and humidity chamber are adhered or burnt out/whether the silicon controlled and the solid-state relay are broken down: replace;


17. Whether the heating tube and heating wire of the executive element of the constant temperature and humidity chamber are grounded: repair/replace.
