Additional Common Errors in ELECTROLUX Air Conditioners

1. Power Loss

• Symptoms: No sound from the air conditioner when opening the fuse.
• Root Cause: Loose circuit, defective fuse, or damaged control board.

2. Remote Control Malfunction

• Symptoms: The remote control sends signals to the air conditioner, but the unit does not respond.
• Root Cause: Faulty remote control, dead batteries, or damaged control board.

3. Unpleasant Odors from the Air Conditioner

• Symptoms: The unit emits an unpleasant smell.
• Root Cause: Gas odor from refrigerant leakage or mold odor due to prolonged lack of cleaning and maintenance.

4. Unit Malfunction

• Symptoms: Water leakage, condensation on the casing, misty air output, or frost accumulation.
• Root Cause: Clogged drainage pipes, slow or non-functional fan, or frost buildup.

5. Lack of Cooling

• Symptoms: Warm and stale air output.
• Root Cause: Low refrigerant levels, faulty outdoor fan, or a malfunctioning indoor control board.
