Why Is The Green Light Flashing On My Daikin Air Conditioner After A Reset?

If the green light returns after a reset, the unit is likely detecting an ongoing issue.

Common causes include:

• Fault code stored in the indoor unit
• Indoor outdoor communication error
• Fan motor problem
• PCB issue
• Sensor fault
• Blocked coil
• Drain issue
• Refrigerant related protection
• Electrical supply fault
• Damaged wiring
• Storm damage

This is when a licensed technician should inspect the system. The unit needs to be tested safely, especially if the outdoor unit is involved.

How To Check For A Daikin Fault Code

Many Daikin split systems allow fault code checking through the remote. The exact process can vary by model, so use your Daikin manual where possible.

A common process is:

1. Find the Cancel button on the Daikin remote
2. Hold Cancel for several seconds
3. Wait for 00 to appear
4. Press Cancel to cycle through fault codes
5. Listen for a long beep
6. Record the code shown on the remote
7. Give the code to your technician

A short beep usually means that code is not the current fault. A long beep usually points to the active fault code.

Do not guess the repair from the code alone. Fault codes guide diagnosis, then a technician confirms the actual cause with testing.

When You Should Call A Licensed Electrician

• The outdoor unit does not start
• The indoor unit opens then closes
• The unit will not respond to the remote
• The green light returns after reset
• Water is near electrical parts
• The air conditioner runs poorly after cleaning filters
• The unit stops during hot weather
• You notice storm damage

Air conditioning faults often involve both refrigeration and electrical diagnosis. East Coast Sparkies can help with the electrical side, circuit safety, isolators, switchboard capacity, split system power supply, and installation support.

Why Gold Coast Homes See Daikin Flashing Green Light Problems

The Gold Coast climate is tough on air conditioners.

Local homes often deal with:

• High humidity
• Long cooling seasons
• Salt air near coastal suburbs
• Storm activity
• Power fluctuations
• Heavy summer usage
• Dust from renovations
• Rental property wear
• Outdoor units installed near gardens
• Older electrical circuits

If your Daikin air conditioner is used daily through summer, the filters, coils, drains, fan motors, sensors, and electrical connections all work hard.

A flashing green light is the system’s way of saying it needs attention before the fault becomes worse.
