1. Is continuous running and cutting off of the air conditioner a fault?
As introduced earlier, the phenomenon of continuous running and cutting off of the air conditioner is very common and can occur at any time. In non-Inverter air conditioner models, due to the use of thermal sensor relays, the air conditioner will run for a while to cool the room. After reaching the set temperature, the air conditioner will automatically shut off. Then, if the temperature rises, the compressor will accelerate to help reduce the room temperature to meet the set temperature on the remote control.

Sumikura APS/APO-280/GOLD air conditioner is a Sumikura Inverter product line. Accordingly, the compressor is integrated with inverter technology during operation, when the temperature has reached the requirement, the compressor will slow down instead of turning off completely.
However, continuous running and cutting off can also be due to a fault in your air conditioner. To determine whether it is a fault or not, you need to base it on the cooling capacity of the device. If continuous running and cutting off occur without ensuring the room's coolness, and you do not feel the cool air flow as per the set temperature, then this is indeed a malfunction. At this point, you need to investigate the cause and take timely measures to minimize energy consumption.
Troubleshooting and Fixing Continuous Running and Shutting Off of Sumikura APS/APO-280/GOLD Air Conditioner
Continuous running and shutting off of the Sumikura APS/APO-280/GOLD 28000 BTU Inverter air conditioner that you have identified is a malfunction. It may originate from various causes.
Incorrect Temperature Setting
Check the remote control of the Sumikura Inverter APS/APO-280/GOLD air conditioner to see if you are setting the temperature incorrectly. You may have set the temperature equal to or higher than the outdoor temperature, leading to the phenomenon of continuous running and shutting off to ensure the correct set temperature.
Solution: Simply adjust the temperature to be lower than the actual temperature of the outdoor environment.

Dirty Evaporator Coil Due to Lack of Regular Cleaning
Excessive Dust Accumulation on the Evaporator Coil of the Sumikura 2.5HP APS/APO-280/GOLD Inverter Air Conditioner is also one of the reasons for the air conditioner running and shutting off continuously. As the air conditioner cannot perform the cooling process effectively.
Solution: You can clean the evaporator coil of the air conditioner at home by cleaning the filter mesh, removing all dust and dirt on it with a small and soft brush (avoid tearing). Then, remember to regularly use the S-Clean feature every 3 months to ensure that the evaporator coil is always clean.

Insufficient or Depleted Gas
Insufficient gas (due to leakage) or gas depletion is also one of the common causes affecting the operation of the air conditioner. Consequently, the machine cannot cool effectively as usual, after a while, it will affect the operation of the equipment, causing the Sumikura Inverter APS/APO-280/GOLD air conditioner to start running and shutting off continuously.
Solution: You should contact repair centers to hire technicians with expertise and experience to check the air conditioner's gas status, consider if there are any leaks, and then propose appropriate solutions. If the gas is depleted, they will refill it so that the air conditioner has the 'energy' source to operate well and cool effectively.
Overheated Outdoor Unit
The outdoor unit is installed outside. When the outside temperature is too high, the Sumikura 28000 BTU APS/APO-280/GOLD air conditioner needs to operate at high and continuous power to meet the users' needs. During this process, if it runs beyond the allowable threshold, the machine will automatically shut off to protect the compressor.

Solution: You need to find ways to arrange the placement of the Sumikura 28000 BTU APS/APO-280/GOLD Inverter air conditioner's outdoor unit in cool places, avoid direct sunlight, you can make a shade for the outdoor unit. At the same time, remove all objects around that affect the cooling process of the equipment.
Above are the causes and solutions to the continuous running and shutting off of the Sumikura 28000 BTU APS/APO-280/GOLD Inverter 1-way air conditioner. Hopefully, with this useful information provided by Mytour.vn, your issue will be effectively resolved.
