When using constant temperature and humidity Test Chambers, we will inevitably encounter situations that require regular maintenance or machine failures. Today, Xiaochao shares a few failure phenomena and solutions for constant temperature and humidity Test Chambers in daily life. Friends who need them quickly look down.
1. The freezer is not running
| reason | Countermeasures |
| (1) Poor contact between plug and socket | check plug |
| (2) The fuse of the socket is blown | Check Outlet Fuse |
| (3) Whether the voltage is too low | Measuring supply voltage |
| (4) Whether the indicator button of the temperature regulator is in the off position | Check the indicator button of the temperature regulator |
| (5) Whether the overload relay is burnt out | Check overload relay |
| (6) Motor burned out | check motor |
2. The refrigerator has been running but the cooling degree is not enough
| reason | Countermeasures |
| (1) Whether the ventilation of the condenser is poor or it is close to the stove, electric stove, or a place exposed to direct sunlight | Check the installation position and adjust the position |
| (2) The adjustment position of the temperature regulator is wrong | Check the position indicated by the temperature regulator |
| (3) The door gasket is leaking, or the door is not closed tightly | close it again |
3. Noise occurs
| reason | Countermeasures |
| (1) The internal disk storage is badly placed | Check internal drives |
| (2) Poor foundation | choose another location |
| (3) Improper placement | check level |
| (4) Whether the piping vibrates with each other | Check pipeline |
4. The high temperature electric heating system does not work
| reason | Countermeasures |
| High temperature protection switch tripped | Check the circuit of the high temperature electric heater |
| The heating tube is damaged | redress |
| Temperature regulator setting is too low | reset |
