The low-temperature coolant circulation pump is not refrigerated or is slow to cool.

1, first look at the compressor surface behind the first look at whether there is dust, the compressor surface adsorption of dust will lead to low-temperature coolant circulation pump cooling speed is slow.
after listening: in the low temperature coolant circulation pump in the refrigeration state, the refrigeration pipe should have the sound of liquid flow, pay attention to this sound is very microseconds, should be carefully identified, if there is a compressor at least not lack of Fleon.
the refrigeration system may leak and cause the compressor to have no cooling fluid.
Touch again: in the low temperature coolant circulation pump in the refrigeration state, at this time by hand to touch the compressor or near the compressor part, there should be jitter sound, if there is a compressor power supply is normal, the reverse should check the compressor power supply and compressor control line.
2, again explained that low-temperature coolant circulation pump does not refrigeration should focus on inspection: refrigeration system, compressor itself and compressor power supply system.
of course a quick solution or recommend to our online customer service to consult our after-sales, whether it is not our equipment can give you advice and help.
3, low temperature coolant circulation pump no temperature display: check whether the circuit board cable is off, the sensor is off, whether the circuit board is splashed with water.
as above are normal, the line control panel should be replaced.
4, low-temperature coolant circulation pump no external circulation: whether the circulation pump is blocked, whether the power box is off, whether the valve is open, whether there is ice phenomenon in the circulation pump.
solution: check the cable, remove the blockage, open the valve.
5, low-temperature coolant circulation pump machine without electricity: leakage protector protection, fuse of insurance pipe, power supply sequence is wrong.
: adjust the position of the two lines of fire, replace the insurance tube, leakage protector reset.
