-60 degree ultra Low Temperature Chest refrigeration

1. After the power is turned on, the air switch of the main power is automatically turned off

Remedy: Check whether the compressor of the *-grade refrigeration system is damaged, and replace the accessories if damaged. After replacing the accessories, turn on and check whether it is normal. This fault is generally caused by the unstable power supply, because the * level starts first, so the damage is usually at the * level. In this case, as long as the delayed power supply is added, the fault will not occur again.

2. The temperature in the box has stopped working before reaching the set temperature

Remedy: Although the set temperature has not been reached, the panel display temperature has reached the set temperature. This is because the thermistor that detects the temperature is damaged and the accessory needs to be replaced. If there are no original accessories, a set of temperature control system can be reinstalled to eliminate the fault.

3. Poor cooling effect may be refrigerant leakage

4. The ultra-low temperature refrigerator does not start in winter, the adjustment value of the thermostat may be too small
