Resetting Daikin Air Conditioner [Explained]
Now that I’ve provided a brief overview of how to reset a Daikin air conditioner in various situations let’s delve into a concise explanation
1. Complete Power Reset (Hard Reset)
The ‘Complete Power Reset’ is a technique for Daikin air conditioners used to resolve power-related issues caused by outages and surges. It helps restore normal operation.
Here’s how to do it,
- Turn Off the Thermostat: Begin by turning off your thermostat. This will ensure that the air conditioner doesn’t immediately attempt to restart when the power is restored, allowing for a more thorough reset.
- AC Circuit Breaker: Locate the circuit breaker or switch on the electrical panel that controls your air conditioner. Turn it off to cut off power to the AC unit. This step is crucial for a complete reset.
- Wait for 60 Seconds: After turning off the thermostat and the circuit breaker, wait for 60 seconds. This brief pause allows any residual electrical charge to dissipate from the system.
- Extend Wait Time: To ensure system stability and prevent potential issues, extend the wait time by 30 minutes. This longer waiting period ensures that the AC unit is entirely reset and ready to operate smoothly.
- Turn the Thermostat Back On: After the extended wait period, turn the thermostat back on. Select ‘Cool Mode’ or your preferred temperature setting to restart your air conditioner. This step initializes the AC’s cooling operation.
2. Reset Button Method
Indoor units on Daikin AC have a reset button that helps reset the AC during cooling issues and noises.
Here is how to do it,
1. Find the Reset Button: Look for a small ” Reset ” button on your AC unit. It’s often near the control panel inside your home or on the outdoor unit. If you can’t find it, check your user manual for help.
2. Safety First: Before doing anything, make sure your AC is turned off and, if possible, unplugged. Safety is important!
3. Push the Reset Button: Gently press the reset button. You might need a small tool like a pen or paperclip to reach it. When you press it, your AC will start a 30-minute self-checkup.
4. Wait for the Self-Check: Your AC will spend 30 minutes checking itself inside. It’s like a doctor giving your AC a checkup.
5. Watch the Lights: Some ACs have lights that blink or change colours while checking. Keep an eye on these lights as they can show if there’s a problem.
6. Check for Error Codes: If your AC finds a problem, it might show a code on the control panel or using the lights. Your user manual can help you understand these codes and determine what’s wrong.
7. Fix Minor Issues: Sometimes, your AC can fix small problems by itself during the 30-minute check. But for bigger issues, follow the instructions in your user manual or call a professional HVAC technician.
8. Turn It Back On: After 30 minutes, you can turn your AC back on. Keep an eye on how it works. If the problem sticks around or worsens, it’s smart to call an HVAC expert for more help.
3. Remote Control Reset
This method is best for fixing unresponsive remotes or when you see error codes on your AC.
Here is how to do it,
- Locate the Remote’s On/Off Switch: Find the switch on your remote control that turns it on and off. It’s usually a small button.
- Press and Hold for 2 Seconds: Hold this button for about 2 seconds. This action is like giving a command to the remote.
