Kelvinator split AC shows E8 and stops cooling; indoor fan may continue to run.

Safety: Disconnect power before opening the indoor unit.

Steps:

• Check for obstructions: Remove the front panel and filters. Inspect the cross-flow blower wheel for foreign objects (plastic, insulation, insects) preventing rotation.
• Spin test: Gently rotate the blower by hand. It should spin freely without grinding. If stiff, the motor bearings may be failing.
• Inspect fan motor wiring: Ensure the fan motor connector is fully seated on the indoor PCB and wires are not damaged.
• Capacitor check (AC motor types): If your Kelvinator model uses a separate fan capacitor, inspect it for bulging or leakage and replace with the same rating if suspect.
• Replace fan motor: If the motor is noisy, overheats, or fails to start even with a good capacitor, replace the indoor fan motor assembly.

Note: Removing the blower wheel and motor can be intricate; consider a technician if you are not experienced with disassembly.
