Press and hold the button for approximately 2 seconds, with all the loads turned off (Motor and Lights), to reset the Filters and turn off the Leds that are lit. After 100 working hours all the LEDs (L1-L2-L3-L4) will light up and remain lit to indicate saturation of the metal grease filters.

When the cooker hood lights do not function, you might be dealing with a defective Light Assembly. There are no replaceable components in the Light Assembly and the entire unit will have to be replaced. If the cooker hood lights fail to function, you can install a new bulb of the correct rating.
