Dryer displays E7 and may not heat correctly or may end cycles too soon.

Safety first: Unplug the dryer before accessing internal wiring.

• Clean sensor bars: Open the door and locate the two metal moisture sensor bars inside the drum (usually near the lint filter). Clean them with rubbing alcohol and a soft cloth to remove dryer sheet residue.
• Inspect wiring: Access the area behind the sensor bars and check the harness connections to the bars and to the control board.
• Check for shorts: Ensure the sensor wires are not pinched or touching each other or the cabinet.
• Test operation: Restore power and run an automatic cycle with a wet load to see if E7 clears and dryness detection improves.
