Whirlpool split air conditioner displays E7 and may not run the indoor fan or may shut down.

Safety: Turn off power at the breaker and wait a few minutes before opening the indoor unit. Beware of sharp metal edges.

Steps to address E7:

• Check for obstructions: Remove the front cover and air filters. Inspect the blower wheel for foreign objects (plastic, insulation, debris) that could jam the fan. Remove any obstructions.
• Spin test: Gently spin the blower wheel by hand. It should rotate freely without grinding. If it is stiff or seized, the motor bearings may be failing.
• Inspect wiring: Check the fan motor harness and connectors at the indoor PCB for loose or burnt terminals.
• Capacitor (if equipped): Some Whirlpool units use a separate fan capacitor. Inspect for bulging or leaking. Replace with the same µF rating and voltage if defective.
• Test operation: Restore power and run the unit in FAN mode. If the fan still does not run and E7 returns, the motor or PCB is likely faulty.

Note: Replacing the indoor fan motor or PCB typically requires disassembling the indoor unit and is best handled by a professional.
