Air conditioner does not start at all; no lights on indoor unit, no response to remote.

Safety: Be cautious when working near mains voltage. If unsure, call an electrician.

Steps:

• Check power source: Verify that other appliances on the same outlet or circuit work. Reset the breaker or replace a blown fuse if necessary.
• Inspect plug and cord (if plug-in type): Ensure the plug is fully inserted and the cord is not damaged.
• Indoor indicator: Look for any standby LED on the indoor Gorenje unit. If completely dark, power may not be reaching the unit.
• Terminal block: With power off at the breaker, remove the indoor cover and check that live and neutral wires are firmly secured at the terminal block.
• Professional diagnosis: If power is present at the terminals but the unit is dead, the indoor PCB or power supply module likely needs replacement.
