Safety: Disconnect power before working near the fan or control board.

Steps:

Check fan operation: With the grille removed, spin the indoor blower wheel by hand. It should rotate freely without scraping. If stiff or noisy, the motor or bearings may be failing.
Inspect fan motor wiring: Locate the indoor fan motor harness and ensure the connector is fully seated on the main PCB. Look for burnt or discolored pins.
Clean blower and housing: Dust buildup can overload the motor. Carefully vacuum or brush the blower wheel and surrounding housing.
Test in FAN mode: Reassemble, power on, and run in FAN-only mode. If E7 appears and the fan does not start or runs erratically, the motor is likely faulty.
Replace motor if needed: Remove the blower assembly and install a new Hotpoint indoor fan motor, transferring the blower wheel if required. Ensure correct wiring and secure mounting.

Note: If a new motor does not resolve E7, the main control PCB may need replacement.

E7 appears on the display; unit may not switch modes correctly or may shut down unexpectedly.
