Step 1: Stay Calm and Turn Off the Unit

The first thing to do when your aircon stops working is to turn off the unit immediately. This helps prevent any further damage, especially if the issue is related to electrical problems or overheating.

Even if your aircon is no longer blowing air or responding to the remote, make sure to switch it off at the power source. Once the unit is off, you can safely begin inspecting the potential causes.

Step 2: Check the Power Supply

One of the most common reasons for an aircon to stop working is a disrupted power supply. Before assuming the worst, check the following:

• Is the aircon plug securely connected?

• Has the circuit breaker tripped?

• Are there any power outages in your area?

If the circuit breaker has tripped, reset it and try turning on the aircon again. If the unit trips the breaker repeatedly, there may be an internal electrical fault—this is where a professional technician from LetsCool should be called in to inspect safely.

Step 3: Inspect the Remote Control or Thermostat

Sometimes, the issue lies not with the aircon itself, but with the remote control or thermostat settings. Check that:

• The remote batteries are working

• The aircon is set to "Cool" mode

• The temperature is set lower than the current room temperature

If your remote or thermostat is unresponsive, try replacing the batteries or using the manual controls on the unit, if available.

Step 4: Clean or Check the Air Filters

Dirty or clogged air filters can restrict airflow, causing the aircon to shut down as a safety measure. Open the front panel of your unit and check the filters. If they look dusty or blocked, they may need a cleaning.

While basic filter cleaning can be done at home, LetsCool Aircon and Services recommends a professional cleaning if you haven’t serviced your unit in several months. Clogged filters are not only a common reason for breakdowns but also reduce cooling efficiency and indoor air quality.

Step 5: Look for Warning Lights or Error Codes

Modern air conditioners are equipped with error indicators or blinking lights that signal specific problems. These codes can tell you if there is:

• A refrigerant leak

• A faulty sensor

• A blocked drainage system

• Compressor or fan failure

Refer to your aircon’s user manual to interpret the error codes. If the meaning isn’t clear or if you suspect a more serious issue, contact LetsCool Aircon and Services for a prompt inspection and repair.

Step 6: Check for Leaks or Strange Sounds

Visible signs like water leakage or unusual noises can give you clues about what’s wrong. Leaks may indicate a blocked drainage pipe, while loud humming or grinding noises might point to a mechanical issue with the fan motor or compressor.

If you notice any of these symptoms, avoid using the unit further. Continuing to run a faulty aircon can make the issue worse and increase repair costs.
