Daikin Air Conditioner Problems: 7 Common Issues (with solutions)

Here are 7 common problems with Daikin air conditioners, along with their solutions to help you handle any issues you face.

Daikin AC Not Cooling

From time to time, Daikin air conditioners can stop cooling the air they blow out

If your Daikin Air Conditioner is nor ot cooling, not blowing cool air it’s likely to be a clogged air filter or defective thermostat.

However, you don’t need to worry, as reading the causes and solutions below might help you solve the issue.

Possible Solution(s):

Thermostat

If your Daikin air conditioner is blowing hot air, the thermostat may have been set to “heat” by mistake. If this is the case, it’s a simple remedy that you can do on your own.

Simply turn the thermostat to “cool” and observe if the air conditioner starts to blow cool air once more.

Check the thermostat and make sure it is set to “cool” and at the proper temperature. If it needs new batteries, replace them.

Dirty Filter

A dirty air filter can lead to a dirty evaporator coil, even though air filters have nothing to do with air temperature.

There may not be enough free airflow to allow for efficient cooling operation if the evaporator coil becomes blocked with dust and debris.

Debris build-up from a filthy air filter can cause frozen evaporator coils.

Although you may believe that “frozen” equals “cold,” the frozen coils actually obstruct the flow of cool air, causing warm air to flow from the running engine instead.

Depending on the environment, filter type, and home, air filter change should be done every 30-60 days by the owner.

Setting a monthly reminder to check the condition of your air filter is recommended.

Daikin AC Not Turning On

At times, your Daikin AC won’t turn on, no matter what buttons you press.

If that’s the case, Daikin AC not turning is typically caused by a simple power failure or tripped circuit. 

Try not to fret, instead work through the steps below

Possible Solution(s):

  • If you’re lucky, your AC might be having trouble turning on only due to a simple power failure such as a loose power cable or a tripped circuit breaker.
  • So, check the main power cable of your AC along with its circuit breaker switch, making sure both are in place.
  • If the AC appears to be getting a constant supply of electricity, then the problem might be inside your AC’s system.
  • Your AC may have some broken wires that are not allowing current to pass.
  • To fix this issue, you will need to call a professional.

Daikin AC is Leaking Water Excessively

It’s expected for a Daikin AC to produce water through condensation.

However, if you start to notice water puddles and excess water leakages, there’s something wrong with your AC.

Continue reading to find out what may be wrong and how to fix it. 

Possible Solution(s):

  • A dirty air filter will block the flow of air, causing coils inside the AC to freeze when the frozen components thaw, and excess water starts to leak outside the AC.
  • So, open your AC unit and clean your filter thoroughly to reduce water leakage.
  • A PVC pipe known as a drain line is used to move the condensation outside in a drain.
  • However, if this pipe becomes clogged, the water can start to leak elsewhere.
