Daikin Troubleshooting

Over time, with regular use, even appliances of the highest quality in terms of construction and components can develop minor problems. Dealing with an air conditioner that isn't functioning properly can be particularly frustrating, especially during a sweltering summer day.

Guide to Fixing Problems with Your Daikin Air-Conditioner

1. Daikin AC Unit Won't Start

Typically, air conditioning systems consume a substantial amount of power to operate efficiently. Consequently, one of the most common reasons a Daikin air conditioner fails to start is due to a blown or tripped circuit breaker.To determine if this is the issue, inspect your switchboard for any tripped switches. If you find a tripped circuit breaker, you can reset it.

However, if it trips again, it's crucial to contact an air conditioning technician immediately and avoid using the system until it's professionally repaired. If the circuit breaker is fine but the AC still won't start or cool, you can attempt a 'hard' reset. This involves turning off the isolator switch located at the outdoor unit and leaving it off for at least 30 minutes.

Afterwards, turn the isolator back on and check if the air conditioner has reset and resumed normal operation. If this doesn't resolve the issue, it's advisable to consult a licensed air conditioning technician for diagnosis and repair.

2. Daikin AC Not Cooling

If your air conditioner isn't emitting cool air, it's essential to first inspect and clean the air filters. Air conditioner filters should be cleaned every 3-4 months or sooner in some cases. Neglecting this maintenance can lead to the accumulation of dust and debris, which can block airflow and impede your air conditioner's performance.

Some Daikin systems offer an 'auto filter cleaning setting,' but keep in mind that an AC unit may not immediately start cooling after a filter cleaning operation.Additionally, double-check the temperature and mode settings on your Daikin remote controller to ensure they are correctly configured.

Regular air conditioning servicing can help prevent dirty or clogged filters and detect potential issues before they escalate into major problems that could lead to system breakdowns.

3. Daikin AC Leaking

While a small amount of condensation is normal for a Daikin air conditioner, excessive moisture, such as dripping from the vents in a ducted system or from the indoor unit in a split system, indicates a problem. In such cases, it's advisable to turn off the unit and contact a professional technician to prevent further damage to the air conditioner and potential water damage to your walls and surroundings.

4. Daikin AC Displaying Error Codes

Daikin air conditioners feature both a green and an orange operation lamp to indicate specific issues to users.To diagnose the problem when the green light is displayed, you can remove the back cover of the remote controller and locate the cancel button.

Holding the cancel button for 5-10 seconds will replace the temperature display with two flashing zeros. Continue pressing the cancel button until you hear a long beep. Subsequently, the zeros on the screen will be replaced by numbers that correspond to specific issues.

One beep indicates an incorrect issue, two beeps mean that one of the numbers displayed is the correct issue, and a continuous long beep indicates that both numbers are correct. To troubleshoot the problem further, consult the Daikin air conditioner fault code page available online.
