Why is my air conditioner not starting after a long period in storage?

Modified on Mon, 24 Aug at 12:36 PM

If your air conditioner was working before storage but will not start now, the cause is often a full water tank, a blocked air path, or a setting that does not match the room temperature. Begin with the simplest checks first, then stop using the unit if it shows signs of damage, smells burnt, or the plug or cable feels unusually hot.

Check the basics first

  1. Make sure the plug is firmly inserted and the wall socket is live.
  2. Confirm the selected mode matches what you need, such as cooling, fan or dehumidifying.
  3. If the water full indicator is lit or blinking, drain the tank before trying again. The manuals state the unit will not start when the water tank is full.

What to observe

If the display or indicator lights come on but the unit still does not begin running, the issue is more likely to be related to a safety condition or an incorrect setting than a complete power failure.

Inspect airflow and surroundings

  1. Check that the air inlet is not blocked by curtains, dust or stored items.
  2. Make sure the hot air exhaust hose is connected and not crushed or obstructed. Poor hose condition is a recognised cause of weak performance in the manuals.
  3. Place the unit on flat, level ground.

When to stop using it

Stop using the air conditioner immediately if you notice a strong electrical smell, visible smoke, leaking water near the power cable or any damaged housing. If the problem remains unresolved after these checks, contact the retailer or store where it was purchased and explain the symptoms clearly.
