Installation and Maintenance

(8) Overload and high discharge temperature malfunction

Main detection points:

●

If the electronic expansion valve is connected well? Is the electronic expansion valve damaged?

●

If the refrigerant is leaked?

●

The compressor overload protection terminal is not connected well with the mainboard?

●

If the overload protector is damaged?

●

Heat exchange of unit is not good? (heat exchanger is dirty and unit radiating environment is bad)

●

Too much load of the system causes high temperature of compressor after working for a long time?

●

Malfunction of discharge temperature sensor?
