Possible Causes

Tripped breaker or blown fuse, Loose power wiring at indoor terminal block, Faulty indoor power supply PCB, Defective main power cord (portable/window units)

How to Fix / Troubleshooting

Safety first: Turn off the breaker before tightening any terminals. Do not work on live circuits.

Steps to check:

  • 1. Check breaker and outlet: Verify the breaker is ON and not tripped. For portable/window units, test the outlet with another appliance.
  • 2. Inspect indoor power connection: Remove the indoor unit cover to access the terminal block. Ensure L and N wires are firmly secured and not burnt.
  • 3. Check remote and batteries: Replace remote batteries and try the manual ON/OFF button on the indoor unit (if present).
  • 4. Look for indicator LEDs on PCB: With power ON (only if you are comfortable and safe), check if any small LEDs on the indoor PCB are lit. No LEDs may indicate a failed power supply board.

When to call a technician: If power supply and wiring are good but the indoor unit remains dead, the indoor PCB or power module likely needs replacement.
