Daikin, the Japanese air conditioner brand, is highly praised for its quality and durability, experiencing minimal breakdowns during usage. However, even the most durable Daikin air conditioners can face unexpected issues after prolonged use. One of the commonly encountered error codes is the H8 error. Let's delve into this error code.
What is the H8 Error on Daikin Air Conditioners?
According to the error code chart provided by Daikin, H8 indicates a fault in the temperature control of the compressor unit, specifically caused by issues with the compressor unit, circuit board, or transistor (active semiconductor component).
The H8 error code commonly occurs in various Daikin air conditioner models, including domestic units, VRV, inverter, and ceiling-mounted types.
Symptoms of Daikin Air Conditioner Error H8
When encountering error H8, Daikin air conditioners exhibit the following symptoms:
+ Indoor unit stops functioning or operates inefficiently.
+ Indoor unit fails to respond to remote control commands.
+ Temperature on the indoor unit does not match the temperature set on the remote control.
+ Power supply to the air conditioner is normal but the unit does not operate.
+ Automatic activation/deactivation of the unit shortly after operation begins.
+ Power loss to the circuit board causing disruption in air conditioning operation.
+ Continuous blinking of the timer light.
+ When checking for errors using the remote control, the screen displays code H8.
Causes of Daikin Air Conditioner Error H8
The primary causes of Daikin air conditioner displaying error H8 mostly relate to technical faults within the device's internal components. Specifically:
+ Transistor/semiconductor component fault: When the semiconductor component malfunctions, the current and voltage in the transmission circuit also become erratic and inaccurate. As a result, the air conditioner fails to respond to commands from the remote control.
+ Faulty compressor capacitor: The compressor capacitor is a component that supports the operation of the compressor motor. If this component malfunctions, the compressor will be unable to deliver refrigerant to the indoor unit, resulting in ineffective cooling.
+ Compressor motor fault: This is a highly complex issue, caused by various factors such as shaft jamming, oil pumping, bearing failure, and wire coil issues. If these components fail, the compressor is forced to operate beyond its overload limit, leading to overheating, compressor failure, and the appearance of error H8.
How to Fix Daikin Air Conditioner Error H8
The H8 error code on Daikin air conditioners is quite complex and difficult to troubleshoot without technical expertise and experience in air conditioning repair. If you have expertise in refrigeration, you can follow these instructions:
+ Step 1: First, check the power transistors of the Daikin air conditioner for any damage.
+ Step 2: Check the connection wires of the variable frequency drive system on the outdoor unit board for any abnormalities or malfunctions.
+ Step 3: Proceed to inspect the external circuit board of the outdoor unit.
+ Step 4: If the transistors and circuit board of the outdoor unit are functioning normally, the next step is to check if the compressor is operating properly. If not, it may need repair or replacement depending on the severity of the damage.
If your Daikin air conditioner displays error H8 and you lack the expertise to troubleshoot, instead of attempting DIY repairs, call the manufacturer's warranty center or a professional air conditioning technician for the quickest assistance.
