Fujitsu Air Conditioner Not Cooling? Here’s What To Do
If there's one thing that can certainly turn a scorching hot summer day into a deeply uncomfortable one, it's discovering your Fujitsu air conditioner not cooling. The brand may be widely known as "Australia's favourite air", and equally regarded for its performance and reliability, but even the best AC units can have their temperamental moments.
From a clogged air filter to refrigerant leaks or a faulty thermostat, these problems not only stop your indoor unit from blowing cold air but can also increase your energy bills and disrupt its operation. Knowing the common causes and some effective Fujitsu air conditioning troubleshooting measures can get your unit working again.
No matter what type of Fujitsu air conditioning system you have, whether it’s a split or ducted air conditioning system, here are some tips to help you bring cool air and maximum comfort back to your home.
Check Your Thermostat and Remote Control
Your Fujitsu AC unit relies on its thermostat and remote working properly for it to continue blowing air that is cool and comfortable.
The first of your Fujitsu air conditioner troubleshooting methods is to check the thermostat setting. Make sure you have it set to cooling mode and it’s at your desired temperature. Sometimes a small mistake like dead batteries in the remote controller can leave your air conditioner unresponsive. Replace the batteries if needed and make sure the remote is working. If the problem persists try resetting the unit to its factory settings using the remote. This will often fix minor issues but can erase your custom aircon settings so be aware of that.
A malfunctioning thermostat can also cause the system to fail on you. If the problem continues, you may need professional assistance. These simple steps will get your Fujitsu split system or ducted aircon functioning correctly again.
Check the Air Filters
A clogged filter is one of the most common reasons for a Fujitsu air conditioner not cooling. Over time air filters can become blocked with dust and debris; they restrict airflow and make your air conditioner less energy efficient. These dirty air filters not only reduce performance but also drive up energy bills and can damage essential components like the evaporator coil.
To keep your Fujitsu aircon system working correctly, check the filters regularly. If they look clogged, clean or replace them as per the manufacturer’s instructions, usually once a month. Neglecting this simple task can lead to bigger issues like poor cooling or strange, unusual noises. Clean filters will get your Fujitsu air conditioning blowing cold, clean air and running smoothly.
Check the Circuit Breaker and Power Supply
A tripped circuit breaker or unstable power supply can leave your Fujitsu air conditioner not cooling or even not working at all.
Start by checking your home’s circuit breaker to see if it has tripped. If it has, reset it carefully but watch for repeated trips as it could point to a more serious issue. A blown fuse, power surge or power outage can also stop your AC unit from working, so check for any electrical issues.
If the air con still doesn’t work, check that it’s connected to a stable and sufficient power supply. Repeated electrical issues may need a professional electrician to check the wiring and control board. Proper power flow will get your Fujitsu air conditioning running smoothly.
Check for Mechanical Issues
Mechanical issues are often the reason a Fujitsu air conditioner not cooling properly. Some are minor, while others will need expert help. Here are a few common ones to check:
- Refrigerant leaks: Reduces your unit’s ability to blow cold air and can damage the compressor over time. For that, you will need a suitably-licensed technician to repair the leak and replace the refrigerant.
- Clogged condensate drain line: Blockages will cause water to leak and disrupt the system.
- Dirty evaporator coil: A dirty coil will restrict the system’s ability to blow cold air.
- Faulty condensate pump: If this fails, leaking water will pool instead of drain.
- Compressor failure: A damaged compressor will cause your inside unit to not blow cold air at all.
Fixing these requires a licensed air conditioner technician to ensure repairs are safe and correct and won’t cause further problems.
Check Error Codes and Flashing Lights
Error codes and flashing lights on your Fujitsu air conditioner are its way of telling you there’s an issue in the system. These indicators can point to problems like your Fujitsu air conditioner swing motors not working, printed circuit board fault or internal components problem.
Common issues include possible refrigerant leaks, clogged condensate lines or control board faults. Fixing these often requires professional help as attempting to fix without the right tools and knowledge can make the problem worse.
Note that error codes can vary between Fujitsu models, so check your manual or online resources to find out what the error code means. Knowing these signals will get your Fujitsu air conditioning back to normal operation quickly and safely.
