Troubleshooting Steps for Daikin Air Conditioner Flashing Green Light

  1. Check for Obstructions:

Ensure that there are no obstructions around the indoor and outdoor units. Restricted airflow can lead to overheating and trigger error codes.

  1. Inspect Air Filters:

Dirty or clogged air filters can impede airflow and reduce the unit’s efficiency. Clean or replace filters regularly to maintain optimal performance.

  1. Verify Thermostat Settings:

Confirm that the thermostat settings are appropriate for your comfort needs. Incorrect settings can cause the unit to operate inefficiently.

  1. Examine Refrigerant Levels:

Low refrigerant levels can lead to freezing issues. Consult a professional technician to check and recharge refrigerant levels if necessary.

  1. Inspect Wiring and Connections:

Check for loose or damaged wiring in both the indoor and outdoor units. Faulty connections can cause electrical malfunctions.

  1. Reset the Unit:

Power off the air conditioner, wait for a few minutes, and then restart it. This simple reset may resolve temporary glitches.

  1. Address Drainage Issues:

Clear any clogs in the drain pipe to prevent the U4 float switch error. Proper drainage is crucial to avoid water damage.

Decoding Daikin Air Conditioner Error Codes

Daikin air conditioners use a sophisticated system of error codes to communicate specific issues. These codes are displayed through flashing lights on the unit’s control panel. Here are some common error codes and their meanings:

A1 – Indoor PCB Malfunction: This error suggests a problem with the indoor unit’s circuit board. A wiring issue, a faulty PCB, or other electrical issues may cause it.

A3 – Fan Motor Malfunction: When the fan motor encounters problems, such as a lack of rotation or abnormal speed, the A3 error code will be triggered. This can be due to a faulty motor or issues with the capacitor.

A5 – Freeze Prevention: The A5 error indicates that the unit is operating in cooling mode, but the evaporator is freezing. This may result from reduced airflow or low refrigerant levels.

U4 – Float Switch Problem: The U4 error signifies an issue with the float switch, typically caused by a clogged drain pipe. This error prevents water overflow and potential damage to the unit.

H6 – Malfunction of position detection sensor: This error relates to a problem with the swing motor or position detection sensor in the air discharge flap. It may cause irregular air distribution.

What is Wrong with Your Aircon?

Decode your air conditioner’s distress with the malfunction code list in your manual. The flashing green light signals trouble in the outside unit – a fan obstruction triggering fault mode. Despite sixteen attempts to fix it, if the issue persists, the indoor unit gracefully shuts down, spotlighting the green light.

In the manual, E7 translates to a motor overrun – the fan struggles with an obstacle. This coded message tells a tale of resilience, troubleshooting, and a graceful acknowledgment of a mechanical impasse. You’re not just facing a green light; you’re deciphering a narrative from your air conditioning system.
