Please check the following if your control panel’s LCD screen is blank or if your machine won’t switch on at all.
Verify that the air conditioning unit’s circuit breaker is turned on in your meter box. Turn the circuit breaker back on if it has tripped. If the circuit breaker keeps tripping, there is a power problem that requires inspection by an expert.
Verify that the unit’s isolating switch, which is often on the wall next to the outside unit, is turned ON. An electrician must inspect and replace the isolating switch if it has a problem, is loose, or is difficult to move.

How does the AC remote work?
You must be familiar with the purposes of each button on the remote control in order to operate the air conditioner with ease.
- Pressing the power ON/OFF button will turn on the air conditioner.
- To set COOL, use the Mode button.
- what each button on the remote control does.
Why isn’t my AC functioning?
There are numerous causes for an air conditioner that isn’t functioning. Filters that are clogged or unclean are frequent causes. Other times, your compressor or refrigerant may be having problems. This may result in your air conditioner not blowing air, not turning on, or just not functioning as it should.
Prior to calling for ac repair, take into account the following:
Check the thermostat
Although it may seem obvious, there are situations when the thermostat is to blame for your air conditioner not working. You might only need to swap out the batteries! Verify that your thermostat is turned on and set to cool. Check to check whether the AC turns on by lowering the temperature a few degrees from the ambient temperature. Seems quite clear, doesn’t it? We’ve saw it occur!
Take a look at the outdoor condenser
It’s time to step outside and look at your condenser if your air conditioner is operating but not pumping out enough cool air. Pollen, weeds, grass, and other debris can occasionally clog the condenser and/or make it unclean. Remove anything that might be in the way in this situation. For the best airflow, a minimum clearance of 3 feet is advised. Check to see if the airflow improves after letting your AC run for a few hours. If not, you might want to think about calling our service staff.
Clean or replace the air filters
Your AC unit’s air filters need to be cleaned or replaced on a regular basis since a dirty or clogged filter prevents cool air from entering your home. If you have a Mitsubishi ductless system, all you need to do is remove the soiled filter, rinse it, let it air dry fully, and then replace it. Check out our video where Chris teaches how to clean Mitsubishi ductless system filters for comprehensive instructions.
The pros at Morris Plumbing, Heating & Air Conditioning can advise you on what size air filter is best for your system if you have a conventional air conditioner. The efficiency of your system should immediately increase when the filter has been changed.
Step 2:Turn breaker off (to the outside unit)
In your home, locate the breaker for the exterior unit of your air conditioner, and then turn the breaker to the “off” position.
Simply locate the circuit with an air conditioning/HVAC designation by opening the circuit breaker box if you’re having problems (next to it).
Quick Tip: Simply seek for the switch that has been “tripped”that is, the one that has shifted to the neutral positionif you do not see any labels.
Step 3:Wait about 30 seconds
Wait around 30 seconds; your air conditioner won’t reset the internal circuit breaker right away. During this period, the internal breaker (in your Mitsubishi air conditioner) should entirely reset.
Why is the Mitsubishi AC light blinking?
Complex electrical equipment like air conditioners can be impacted by the climate. For example, accumulated dust and dirt on the outside grille can affect the performance of your aircon. The air conditioner’s light blinking typically indicates that it needs to be repaired because the machine has identified an internal problem. The majority of air conditioning manufacturers have included a flashing air conditioner light on their products to let users know when an internal problem needs to be fixed. Here are seven typical causes of blinking air conditioning lights.
Poor Air Circulation
If your aircon unit is unable to circulate air properly, you may experience aircon not cold issue. This may be the result of improper air conditioning installation or an issue with the air conditioning drive motor. The user manual for the air conditioning device should be used to verify any trouble codes it displays.
The majority of manufacturers enable an error message to be shown on the remote control or control panel of their air conditioning units. You might need to work with an air conditioning maintenance business if the error number is not listed in the user manual.
Refrigerant Leak
An air conditioner needs refrigerant gas to operate at its best, thus it’s crucial. Without enough refrigerant, condensation could happen, which could lead to the condenser freezing and eventually causing air conditioning leaks. The compressor unit may become damaged due to a lack of refrigerant, and a hissing sound may be heard.
An air conditioner gas top-up is mainly used to address low refrigerant levels. The expert air conditioning maintenance company will fix the refrigerant leak and any associated air conditioning problems. As soon as you notice that your air conditioner is leaking refrigerant, you should call an air conditioning maintenance firm since refrigerant leaks are extremely dangerous to both your health and the environment.
Clogged Air Filters
The evaporator unit can operate more smoothly and produce more powerful, clean air when the air conditioner’s filters are clean. Lack of maintenance causes dust to build up in your air conditioner, increasing the likelihood of clogged filters and unpleasant odors. You should make sure that your air conditioner filters are cleaned at least once every three months in order to prevent airflow obstruction in the evaporator coil. The evaporator coils will freeze if they are neglected, and when the coil melts, water leaks will follow.
It is best to get in touch with a qualified professional for aircon chemical overhaul if deep cleaning is necessary.
Frozen Evaporator Coils
If this alarm sounds, it is best to pay close attention right away because it can cause an emergency water leak from the air conditioner. A problem in the ducts may potentially be the source of frozen evaporator coils.
Open the front panel of your unit and look to see whether an ice deposit has formed on the evaporator fan coils to determine if they have frozen. If your air conditioner’s evaporator coils are frozen, you might need to quickly turn off the compressor while you wait for the evaporator temperature to raise. If the problem continues, you should get in touch with an expert air conditioning servicing firm.
Poor Maintenance
An air conditioner will experience problems and malfunction if it is not properly maintained. Therefore, it is crucial to frequently examine and maintain it. Maintaining your air conditioner regularly can ensure that it is always clean and that you can breathe cool air.
The flashing light may occasionally be a sign that the air conditioner needs to be serviced. If your air filters are clogged, you should first try troubleshooting before calling an air conditioning service.
Incorrect Installation
The Daikin Aircon Light Blinking will occur to show that your air conditioner installation was unsuccessful if it was performed by untrained, inexperienced workers.
In this specific instance, a flashing light denotes a Daikin air conditioner issue. When this light flashes, it’s crucial to identify the underlying issue by figuring out the error number that was generated or consulting the user guide. To make sure that your air conditioning installation is done correctly and operates without a hitch, we always suggest selecting a professional with a lot of favorable evaluations.
Electrical Fault
There are two frequent causes of electrical faults in air conditioners: faulty electrical wiring or a broken PCB (printed circuit board).
- Read the owner’s manual. To start troubleshooting your air conditioning problem, look for the associated error number; it might assist in determining the reason and provide direction.
- Examination of the printed circuit board The air conditioning compressor may stop working if there is moisture or water on the PCB.
- Do not get involved if it is clean. If you see any filth, carefully clean it with an alcohol solution and a cotton cloth.
- Electrical wiring should be examined. The issue can be inside the appliance if it is blowing air. Look for blown or blown-out components.
- Check the electrical wiring protection components if the device won’t turn on. Perhaps a fuse or breaker has blown. Check the ground wire as well, as this provides protection from transient surges.
However, it is always advised to get in touch with a reputable air conditioning servicing business if such a problem arises because they would be outfitted with the necessary technical know-how and equipment to fix it.
Test for Error Code
In Singapore, practically all air conditioning models have a setting that causes the aircon light to blink to indicate a potential equipment issue.
First, check your air conditioner’s brand manual and search for any error codes that pertain to your issue. The information contained in error codes is crucial for locating the underlying issue. You should consult the manual for each piece of equipment if you have different types of air conditioning because the error codes vary by brand and model.
The troubleshooting manual is another resource you could use. To make sure that your air conditioning equipment does not experience any further issues, it is advised to hire a professional for air conditioning services.
Inspect Your Aircon for Loose Wiring
A sudden power draw or unusual power load on the air conditioner will probably cause the Daikin aircon light to flicker. This can be the result of issues with the electrical wiring or PCB (printed circuit board).
Insulation and continuity tests must be performed by a skilled expert in order to identify and address the issue.
It is advised to repair the faulty component as soon as possible if the PCB or a power line is malfunctioning.
Installing an air conditioner socket would guard against power overload for your air conditioner and other home appliances.
Check for other symptoms
When the outside temperature is warm and your Mitsubishi air conditioner does not shut off the compressor, the condenser probably needs to be serviced. It should be serviced at least once a year to keep it in good working order. Your Mitsubishi air conditioner will operate more efficiently and save you money if you maintain it properly.
Conclusion
Blinking air conditioner lights are a common problem, especially if the air conditioner hasn’t had the required maintenance over a long period of time. However, it is not always an emergency with the air conditioning. To solve the problem, however, it is always advised to contact an air conditioning servicing firm.

Why won’t my Mitsubishi air conditioner remote work?
Before scheduling a diagnostic callout, try the procedures below if your air conditioner is not responding to the remote control.
First, examine if you can read the information on the remote’s display to determine if it is functioning. If not, changing your batteries will probably remedy the problem. Simply slide the remote panel down to show the other buttons on a split system remote control before changing the batteries. Give it one more tug once it stops to completely remove the panel. We’ll see the battery compartment. Replace the batteries and make sure the metal parts are not rusted. Make sure you are using the right batteries by checking the user manual again. Also, remember to check the remote to make sure you inserted the batteries correctly.
You can try a different remote on the unit that isn’t working if you have one in your home that you use for another split air conditioner of the same type. If this remote controls the air conditioner, the other one is broken and needs to be replaced.
The remote control’s top LED light will now need to be examined. The sensor on the interface of the air conditioner unit receives signals from the LED light. The LED may have separated from other internal parts if you dropped the remote control. If you want to verify that the remote control is correctly sending a signal from the LED, you will need an infrared sensor card.
Your closeness to the unit is another factor. The sensor on the surface of the unit cannot be blocked by furniture or other objects, and the remote must be within 10 meters of the unit for it to work. Make sure the sensors are cleaned to remove any dirt that might be causing interference. Moisture is another major factor in remote control damage. Your remote control can cease working if it is exposed to liquids like a spilt beverage or other liquids.
To make sure your remote is functioning, try excluding the possibility that the problem is with the actual device.
To test whether they function, manually press the buttons on the device’s bottom right side. If they do, but the remote does not activate the device, you can conclude that the remote’s signal is either not getting through to the device or is not being recognized.
If the remote’s malfunction has been checked out, reset the system by shutting off the main power and leaving it that way for around 30 minutes. After turning the power back on, if the issue still exists, we advise scheduling a service call so a technician may do a system diagnostic check. We might find that the indoor unit’s board has to be replaced because it is no longer communicating with the remote. We’ll check the remote to determine if it’s broken as well.
By keeping your handheld remote control in the wall holder that was provided when the system was installed, you can increase its lifespan. We advise buying a brand-name model rather than a knockoff when replacing a remote control. Although they probably won’t offer the entire range of functionality, universal remotes may provide you with the necessary operations. Your air conditioner warranty includes coverage for faulty (but not damaged) remotes.
Without a remote, how can I turn on my ductless air conditioner?
In order to activate the inside unit of a ductless (split air) air conditioner without a remote control, press the “Emergency Run” button with a non-metallic pen or pencil. The button is located in a slot on the right side of the case, underneath the unit cover. To set the device in Auto Mode, simply hold down the Emergency Run button for 1 second after pressing it. The device will continue to operate at 79 for cooling and 73 for heating while in this mode.
