Common faults of high and low temperature constant temperature circulation device.
1. If there is no temperature display, check whether the connecting wire of the circuit board falls off, whether the sensor falls off, and whether the circuit board is splashed with water. Then you need to plug in the connecting wire again, dry the circuit board and start it.
2. No cooling or slow cooling speed, leakage or dirty blockage of the circulating pipe.
3. There is no external circulation. Check whether the circulating pump is blocked, whether the power box falls off, whether the valve is open, and whether there is ice in the circulating pump. Arrange technicians to recheck the connecting line, eliminate the blockage and open the valve.
4. The whole machine has no power, the leakage protector trips, the fuse is blown, and the phase sequence of the power supply is wrong. The user can adjust the position of the two live wires, replace the fuse, and reset the leakage protector.
