Electric range shows E41 and the clock/timer functions erratically or reset themselves.

Safety first: Turn off power at the breaker before accessing wiring.

• Check terminal block: Inspect the main terminal block at the rear of the range for loose or burned connections, especially the neutral. Tighten or replace as needed.
• Inspect harness: Follow the wiring from the terminal block to the control board. Look for pinched, burned, or broken wires and repair or replace.
• Measure supply: With power restored (qualified person only), measure voltage at the control board input. Ensure it matches the rating plate.
• Control board replacement: If supply is stable but E41 persists and the display resets or flickers, the electronic control board power supply section is likely faulty and the board should be replaced.
• Re-test: After repairs, verify stable clock operation and that E41 no longer appears.
