Mitsubishi Aircon

When it comes to staying cool in Singapore's hot and humid climate, Mitsubishi air conditioners are one of the most reliable and energy-efficient choices. However, like all appliances, even the best units may occasionally face issues. Whether it's weak airflow, water leakage, or unusual noises, knowing how to troubleshoot your Mitsubishi AC can save time, money, and discomfort.

In this article, COOLCARE AIRCON, Singapore's trusted AC servicing and repair expert, shares practical tips and common troubleshooting steps for Mitsubishi aircon systems used in HDBs, condos, offices, and commercial spaces.

Why Choose Mitsubishi Air Conditioners?

Mitsubishi Electric has long been known for its high-quality, energy-efficient air conditioning systems. With advanced technology, quiet operation, and long-lasting durability, Mitsubishi AC units are a popular choice for homeowners and businesses alike in Singapore.

But even the best systems can experience problems, especially with regular wear and tear, lack of maintenance, or sudden changes in weather conditions.

Common Mitsubishi Aircon Problems in Singapore

Here are the most common Mitsubishi AC issues faced by users in Singapore:

1. Aircon Not Cooling Properly

One of the most reported issues is when the AC doesn't cool as expected. This could be due to:

  • Dirty air filters



  • Low refrigerant levels



  • Blocked condenser unit



  • Faulty thermostat sensor



2. Water Leaking from the Indoor Unit

Water dripping is often caused by:

  • Clogged or dirty drainage pipes



  • Frozen evaporator coils



  • Poor aircon installation



  • Drain pan issues

Grinding, buzzing, or clicking noises can be a sign of:

  • Loose fan blades



  • Failing motor bearings



  • Electrical issues in the circuit board



  • Debris in the outdoor unit



4. Aircon Unit Not Turning On

If your Mitsubishi AC  won't start:

  • Check the power supply



  • Inspect the remote control batteries



  • Ensure circuit breakers haven't tripped



  • The PCB (Printed Circuit Board) could be faulty



DIY Troubleshooting Tips

Before calling a professional, you can try some simple troubleshooting:

Clean the Air Filters

Dirty filters block airflow and reduce efficiency. Clean them every 2-4 weeks, depending on usage.

 Reset the Aircon Unit

Sometimes, simply resetting the unit can fix glitches. Use the reset button on the remote or turn off the main power for 5 minutes.

Inspect for Error Codes

Mitsubishi aircons display error codes on the panel. Refer to your user manual or check the Mitsubishi Electric website for meanings.

Check the Remote Control Settings

Ensure the mode is set to “Cool” and not “Fan” or “Dry.”
