Fix Daikin AC Not Working – An Ultimate Guide
There’s no better feeling than walking into your air-conditioned home after work on a hot summer day. Your Daikin AC unit turns on, blasting cool air throughout the house—until one day it suddenly doesn’t and stops working! What can you do?
One day, I went home from the job and was really exhausted. I turned on my Daikin AC and it did not work at all. I was exhausted further and did not know how to cope with the situation so I had to call an expert to get the help.
While troubleshooting your Daikin AC might not be your idea of fun, it will save you time and money in the long run if you catch the problem early on. The first thing to check is when your AC unit isn’t working right? The light!
There is a loose power cord
Before you do anything else, it’s a good idea to make sure that your power cord is properly plugged in. The following procedures will assist you in troubleshooting your Daikin AC if it is malfunctioning:
Check for loose plugs at both ends of the power cord (connecting to your window air conditioner and plugging into an outlet). Unplug one end from an outlet and plug it back in. Plug your other end of the power cord into another nearby outlet, then unplug that one.
Re-insert your unplugged end of the power chord into a wall socket. If you still don’t see any indicator lights come on, contact Daikin customer service.
How to fix Daikin Air Conditioner Problems
Most people assume their Daikin AC is broken when it won’t start or stops midway. Usually, a loose power cord is to blame. If you feel like your power cord isn’t securely plugged into an outlet, don’t assume it’s faulty- just make sure you’re connecting it right.
Outlets that use push and lock mechanisms are really easy to fix yourself with a little finesse. Make sure the two plugs on either side of the plug release buttons are firmly pushed and locked together before trying to use your device. And keep in mind- if one side of your plug doesn’t want to connect, don’t force it! It’ll end up breaking the outlet if you do.
The Air Filter has been missing or destroyed
There are few things worse than hot weather and a bad air conditioner. However, you don’t have to sweat it if your air conditioner is malfunctioning because sometimes all you need to do is get the right part.
The good news is that replacement parts are pretty cheap, so you don’t have to spend a lot of money fixing your machine. Most of the time when people complain about their Daikin AC not working or just having sporadic problems, it’s a matter of replacing the filter in order to put cool air back into their homes or offices.
If that doesn’t work, then chances are that something else has gone wrong.
The switch has been disabled
If you’ve checked all the usual trouble spots (fuses, circuit breakers, circuits), and your thermostat is set to on, but your air conditioner still isn’t turning on, it could be that your thermostat has been switched off.
If you are only using one thermostat and both zones are not responding, then this is almost certainly the problem. This can happen when there is a power outage or if someone bumped into it.
Just turn it back on to see if it fixes the issue. Otherwise, make sure that the breaker hasn’t been tripped by flipping it on again and pressing reset.
The breakers are not switched on
The first thing to check is the breaker that controls power to your Daikin air conditioner. It could be in your home’s electrical box, basement, or fuse box. If it’s on and is labeled as AC, turn it off and then back on again to see if it works.
Then, look for any indication of a circuit problem, such as blown fuses or tripped breakers. Make sure that you have power over other circuits with breakers before checking for fuses or circuit breakers in your Daikin air conditioner.
If there are no other issues with the circuit, check for a short by turning off all power sources to your Daikin AC unit. After that, flip switches one at a time until the compressor starts running. Once you find an issue, fix it right away so you can enjoy cool indoor temperatures this summer.
The internal cooling coil is obstructed or filthy
Your Daikin ac unit won’t turn on if your internal cooling coil is obstructed or dirty. There are a few things you can do to check for obstruction before calling a repairman. First, feel behind the external filter for heat.
If it’s warm, then your coil is blocked by dust, leaves, paper, or other objects that have made their way into your cooling system. Secondly, look inside and see if anything visible can be seen on top of or below the fins that form your internal cooling coil.
Thirdly, hold up a mirror at an angle and look down into your internal unit to see what is obstructing it from getting cold air circulating around it properly.
Troubleshooting guide if your Daikin Air Conditioner is not turning on
Did you know your Daikin air conditioner doesn’t need to be running in order for it to be cooling? Make sure that there is no debris blocking the airflow. Check to see if there are any objects on top of or nearby your air conditioner.
Is it a hot day outside and want some relief now? To cool things down quickly, spray water on the condenser coils with a hose or power washer. This will cool them down faster and improve efficiency. If none of these steps have solved your problem, it’s time to call for professional help.

What do the blinks mean?
Your Daikin air conditioner’s digital Display will start to flicker and will show distinct fault circumstances as well as what you should do to troubleshoot them. If the green LED on your air conditioner is blinking, it signifies there is a high-voltage power supply problem.
You should immediately turn it off and back on while keeping a close eye on it. The refrigerant circuit has a current issue shown by the blinking red Display; you should contact a service provider.
The flashing green/red LED means there is an overheating in system parts or potential mechanical trouble. You should lower the temperature setting of your Daikin Air Conditioner while contacting Daikin customer service to investigate this issue.
If none of these lights are lighting up, then your Daikin Air Conditioner is ready to go and needs no further troubleshooting.
