Regarding newly purchased Inverter AC of Hitachi

The issue can better be sorted out by the authorised technician. Some of the possible issues can be

• Check the oil in the compressor. If the oil is leaking, the compressor may be getting heated up and shuts down.


• You may also check the condenser unit. If there is a lot of dust or dirt on it, that could be one of the causes for the issues. Too much dirt can hamper proper heat dissipation.
• There can be a safety switch involved in this case which is switching off your compressor. You may need to check for the issues that has been activating this safety switch.

In any case, please note that ACs are not meant for self repair. The best option would be to show it to different technicians and get their estimate for the exact problem.

Modern ACs have the temperature sensors that send the signal to the core for balancing. You can find that if room that has the AC maintained temperature if gets some change, it'll try to reshuffle itself to adjust to new temperature. So sudden drop in the temperature may make the compressor to go on and off. And if there is a rise in temperature then it'll keep itself on to maintain to the adjusted number. This is an expected behavior.

But if your AC's compressor is suddenly turning itself on and off then it can't be a right scenario. In such case it's sensor and core communication must be having issues. You should consult with the AC service center. They should be able to take care of this. Considering this is more of circuit issue, they may need to take the unit to the service center. If it's the sensor or due to any circuit issues, that may cost some but before make sure they do basic diagnostic and verify if the problem is with sensor or circuit.
