How to Reset a Daikin Air Conditioner

A Daikin air conditioner is known for its efficiency, reliability, and cutting-edge technology, but like any electrical appliance, it may occasionally require a reset. Resetting your Daikin aircon can help resolve common issues such as error codes, temperature inconsistencies, or unresponsive controls.

In this guide, we’ll walk you through how to reset a Daikin air conditioner, including Daikin split systems, ducted air conditioning, and wall controllers.

Why Reset a Daikin Air Conditioner?

Before performing a reset, it’s essential to understand why your Daikin air conditioning system may need one. A reset can help fix:

  • Error codes on the display panel
  • Unresponsive Daikin aircon remote control
  • Fluctuating temperature settings
  • System freezing or not cooling/heating properly
  • Issues after a power outage

Resetting your Daikin air conditioner can often restore normal operation without requiring professional servicing.

How to Reset a Daikin Air Conditioner: Step-by-Step Instructions

1. Resetting a Daikin Split System Air Conditioner

If your Daikin split system air conditioner is not functioning correctly, follow these steps:

  1. Turn off the air conditioner using the remote control or the Daikin wall controller.
  2. Locate the power switch on the indoor unit (if accessible) and turn it off.
  3. Switch off the power supply to the unit at the circuit breaker or main power switch.
  4. Wait for at least five minutes to allow the system to reset.
  5. Turn the power supply back on at the main switch.
  6. Turn on the air conditioner using the remote control or wall panel.

At this point, your Daikin air conditioning system should be reset and functioning normally.

2. Resetting a Daikin Ducted Air Conditioner

For Daikin ducted air conditioning systems, the reset process is slightly different:

  1. Turn off the system using the Daikin wall controller.
  2. Locate the circuit breaker switch for your Daikin ducted unit.
  3. Turn off the breaker switch and leave it off for at least five minutes.
  4. Switch the breaker back on and wait for the system to restart.
  5. Use the wall controller to turn the system back on and adjust your settings as needed.

3. Resetting a Daikin Air Conditioner Remote Control

If your Daikin aircon remote is unresponsive or displaying incorrect information, you may need to reset it separately.

  1. Remove the batteries from the remote control.
  2. Press and hold any button for at least 5 seconds to discharge any remaining power.
  3. Reinsert the batteries, ensuring they are correctly positioned.
  4. Point the remote at the unit and try turning the system on.

If your Daikin aircon remote still isn’t working, check the Daikin air conditioner manual for further troubleshooting or consider replacing the batteries.

4. Resetting a Daikin Wall Controller

If your Daikin wall-mounted controller is displaying an error or not responding, follow these steps:

  1. Turn off the air conditioner using the wall controller.
  2. Press and hold the ON/OFF button for five seconds.
  3. Wait for the screen to go blank, then release the button.
  4. Turn the system back on and reconfigure your settings if necessary.

What to Do If a Reset Does Not Fix the Problem?

If your Daikin air conditioner is still not functioning correctly after a reset, consider the following:

  • Check for blocked air filters – Dirty filters can affect airflow and efficiency.
  • Ensure the power supply is stable – Frequent power interruptions can disrupt normal operation.
  • Look for error codes – Your unit may display an error code that requires professional servicing.
  • Consult the Daikin air conditioner manual for additional troubleshooting steps.

If problems persist, contact a professional Daikin aircon technician for assistance.

Daikin Air Conditioner Reset FAQs

  1. How often should I reset my Daikin aircon?
    Resetting your Daikin split system or ducted aircon is only necessary when troubleshooting an issue, such as an error code or unresponsive controls.
  2. Will resetting my Daikin air conditioner delete my settings?
    Yes, a reset may erase custom settings such as timers and temperature preferences. You may need to reconfigure them after resetting.
  3. Why is my Daikin aircon still not cooling after a reset?
    If your Daikin AC is still not cooling properly, check for blocked air filters, refrigerant leaks, or incorrect thermostat settings. If the issue persists, contact a Daikin specialist.
