1.  If the Drug stability test chamber doesn't respond after turning power on
A. Fuse is damaged, replace with a new one
B. Switch is damaged, replace with a new one
C. If the main control board is damaged, use a multimeter to measure the main control board to see if it is normal, if it is not normal, that means it is the front power supply circuit failure.
2. If the display shows normal but the temperature does not rise
A. Heat pipe damaged, replace with a new one
B. Host board damaged, use a multimeter to measure the voltage value of its load out terminals to determine
3. The display shows normal but the humidity does not reach the set value (such as the humidity control function)
A. Humidification tube is damaged, replace with a new one
B. Host board damaged with a multimeter to measure the humidity output terminal, no output voltage.
C. Water into the electronic valve is damaged, resulting in water into the water tank, resulting in insufficient water level.
D. Water level switch is damaged
4. Illumination can not be set or can not reach the set value (such as a light function)
A. Check whether the lamp is connected or not, and replace the burned-out with a new one
B. The control board cannot be set, check and replace.
5. Turn on the switch, the equipment trips
A. Heating tube leakage
B. Humidification tube leakage
C. Fan leakage               
D. Compressor leakage
E. Leakage from lamp line set
Use a multimeter to measure and exclude respectively
6. If the temperature display "----" or the alarm goes off after a while
A. Temperature sensor failure, replace with a new one
B. Water shortage
7. The temperature does not come down, the display temperature is always higher than the set temperature
A. Compressor cooling performance decline, replenish refrigerant
B. Compressor does not work, replace with a new one
C. The water level switch is damaged
