Important Tips for None Models

  • Flashing lights can specifically indicate grease filter cleaning reminder and require a reset procedure per manual.
  • LED 1/LED 2 flashing can represent grease/charcoal filter service indicators; reset per model instructions.

Possible Causes

Filter or maintenance reminder indicator

How to Identify: Flashing occurs without functional failure of lights; occurs after extended use; often remains after cleaning filters until reset

Part: Control/indicator circuit

Switch lock or control lock feature active

How to Identify: Buttons unresponsive and lights flash; audible beep when pressing buttons; recent cleaning or transit might have triggered lock

Part: Control panel/lock mechanism

Loose wiring or connection issues

How to Identify: Intermittent or irregular flashing, possibly accompanied by flickering of bulbs or other functions

Part: Internal wiring/sockets

Faulty LED driver or control board malfunction

How to Identify: Flashing persists after reset and cleaning; other controls behave erratically

Part: LED driver/control PCB
