Sumikura 1-Way APS/APO-120/Morandi air conditioner is not only affordable but also aesthetically pleasing, quick to cool, and highly durable. Hence, it is chosen by many households, offices, restaurants, etc., for installation.
After a period of use, one day you turn on the Sumikura 12000 BTU APS/APO-120/Morandi air conditioner but the control panel and the indoor unit continuously show F4 error. According to technical experts, this error code indicates a malfunction in the fan of the indoor unit. So, what are the causes and how to troubleshoot? Mytour.vn will guide you in detail for your reference.
1. Unstable Voltage
Unstable or weak voltage below 180V is one of the reasons why the indoor fan fails to operate, thus affecting the cooling process of the Sumikura 1-Way APS/APO-120/Morandi air conditioner.
To fix this issue, consider purchasing an additional stabilizer device to ensure stable power supply for efficient operation of the Sumikura APS/APO-120/Morandi air conditioner.
2. The fan motor of the Sumikura 1-way APS/APO-120/Morandi air conditioner is malfunctioning.
If it's not due to unstable voltage, check the motor wire component or the fan motor of the indoor unit for any faults. A broken motor wire or a faulty indoor unit motor is a direct cause of the fan in the 12000 BTU Sumikura APS/APO-120/Morandi air conditioner not functioning.
To address this, if you have technical knowledge in electrical or refrigeration systems, you can reconnect the motor wire or replace the motor when they are faulty. If you lack experience, it's best to call a technician to inspect and troubleshoot. Avoid attempting repairs yourself as it may affect other components of the indoor unit.
3. The temperature sensor of the Sumikura 1-way APS/APO-120/Morandi air conditioner is faulty.
The temperature sensor, also known as the temperature control sensor, plays a role in regulating the temperature on the indoor unit and the room temperature. When the room temperature reaches the set level, the device will automatically adjust the cooling capacity and stop the compressor.
If the temperature sensor component of the Sumikura 1-way APS/APO-120/Morandi air conditioner's evaporator fails, it can also cause the internal fan component of the evaporator to malfunction. Identifying and resolving this issue requires the expertise of a skilled technician to ensure accurate and effective repair without affecting other components.
4. Faulty evaporator circuit board in the Sumikura APS/APO-120/Morandi air conditioner
As you may know, the circuit board, also known as the motherboard in the evaporator, plays a central role in the air conditioner. This component is responsible for connecting the various components together and facilitating communication between them through the motherboard. The control buttons of the Sumikura APS/APO-120/Morandi air conditioner are located on the electronic board of the motherboard.
If this circuit board component is damaged, it can lead to the evaporator fan not operating and failing to cool your room space. However, this is a complex issue, so you should not attempt DIY repairs at home. Pick up the phone and call a technician with the technical expertise and experience to help you troubleshoot and repair effectively.
