Solutions to common faults of Hitachi air conditioner;
1. The fan of the outdoor unit of Hitachi air conditioner does not turn: in this case, the parts related to the fan are mainly checked, such as the motor itself (the mechanical part of the coil resistance), starting capacitor, relay, etc. Generally, there is something wrong with the motor or the capacitor is damaged.
2. Hitachi air conditioner can't be turned on: under normal circumstances, the fuse or circuit board should be broken, so you should check whether the socket or air switch has 220V voltage. Remove the air conditioner housing and check whether there is 220V voltage on the circuit board. If not, please check the power cord. Check whether there is 220 volts at the transformer primary. If there is no voltage, it may burn out. Check safety and pressure sensitivity.
3. Hitachi air conditioner leaks water: There are several reasons for this problem: if it is a new machine, it is necessary to consider whether the arrangement of internal machines is horizontal; It is very likely that the drainage is not smooth. Blow hard at the air conditioning drain pipe to see if it works. Check whether the drain pipe connector on the back of the internal machine is loose.
