F41 error, oven may not start or may reset intermittently.

Safety first: Isolate the oven from mains.

• Check mains stability: If other appliances flicker or reset, there may be a supply issue; contact your electricity provider.
• Inspect terminal block: Tighten all screws on the oven’s mains terminal block and check for heat damage.
• Surge protection: Consider using a surge protector or dedicated circuit if supply interference is suspected.
• Board replacement: If F41 occurs only on this oven and wiring is sound, the internal power supply or frequency detection circuit on the control board may be defective.

Warning: Repeated resets can stress electronic components; resolve the underlying issue promptly.
