Why Reset Your Daikin Air Conditioner?

Generally, resetting a Daikin air conditioner allows you to fix specific issues that don’t need expert help, at least not before you try it DIY. Such problems include the following:

1. When The Daikin Air Conditioner Won’t Turn On

The Daikin air conditioner won’t turn on for different reasons, such as power failure, thermostat fault, or clogged filter. You can try resetting it first, especially if there’s power.

The problem might not be severe, and the reset may fix it. It’s only when the AC won’t turn on after a reset should you call an expert. 

2. When The Daikin Air Conditioner Won’t Work After Power Outage

After a power outage, the Daikin air conditioner’s circuit breaker kicks in, protecting the AC from a power overload once the power returns. Unfortunately, that causes a thermostat fault.

So, the AC won’t start. That’s until you reset it. So, a reset is advisable to get the thermostat and AC back working after an outage. 

3. When Daikin Air Conditioner Won’t Heat or Cool

Yes, issues like clogged filters, low refrigerant, and thermostat faults are the most likely reasons an air conditioner fails to heat or cool. But before you can get into these issues, consider resetting the air conditioner.

You could get the unit blowing hot or cold air after a reset, saving you the time of calling an expert.

4. When Daikin Air Conditioner Turns Off by Itself

You should reset not only a Daikin air conditioner that won’t turn on but also one that turns off by itself. If the reset doesn’t fix the AC, you can consider issues like a faulty thermostat, power failure, and a faulty compressor, circuit board, or condenser.

5. When The Daikin Air Conditioner Lights Flash

Usually, the Daikin air conditioner operation lamp blinks green to show a dusty/dirty dust box. In that case, you should clean the dust box.

Once you do that, the green light should stop flashing. If it doesn’t, you should reset the air conditioner. The reset will stop the operation lamp from blinking. 

6. When There’s an Error Code on Your Daikin Air Conditioner

If there’s an error code on your Daikin air conditioner that you cannot interpret, consider resetting the AC first. In most cases, you only need to disconnect the AC from the power or reset it using the remote control to eliminate the error code.

7. When The Thermostat Malfunctions

Given that the thermostat regulates the AC’s temperature, you wouldn’t want it to fail. Once it starts to malfunction, you cannot control the AC’s essential functions, like heating and cooling.

You can fix it most of the time by resetting it. A reset will fix the issue, and your device’s thermostat will now properly control your indoor temperature. A thermostat reset returns the thermostat to its factory/default setting. 

8. When The Timer Malfunctions

The thermostat is not the only AC component that you can reset. You can also do the same for the timer. Usually, this requires turning the timer on and off, which you can do seamlessly. 

9. When The Daikin Air Conditioner Remote Control Won’t Work

The Daikin air conditioner remote control may fail to respond for different reasons. Often, the issue is the batteries. If they are dead or just wrongly loaded, the remote won’t work. So, you expect it to work once you replace the batteries and load them correctly.

But if the AC still won’t respond to the remote, consider resetting the remote control. Luckily, most Daikin AC remote controls have an on/off switch, which you can press to reset.

10. When The Daikin Air Conditioner Makes Strange Noise

Daikin ACs can make strange noises that you can fix by resetting them. Often, all it takes to resolve an abnormal sound is to unplug the AC from the power. That includes any strange noise when cleaning the air filter.
