5. Fridge Lamps

Inside the multiflow there are two lamps used to illuminate the refrigerator

compartment. The lamps are connected in parallel, therefore the electronic board

controls them at the same time.

The lamps stay on when the refrigerator door is kept open in appliance On conditions,

i.e., as well as being connected to the electric grid, the appliance must have been

switched on by means of the ON/OFF key on the user interface for models with

display, or a position other than stop on the freezer knob for models with knobs.

The lamps are switched off when the door is closed.

Particular situations

• Refrigerator Door: if the door is kept open for more than 2 minutes, the lamp is

not kept on continuously, but is switched on and off and regular intervals; if the

door remains open for 7 minutes or more, the frequency of flashing increases.

POSSIBLE CAUSE OF MALFUNCTION:

Board management

Refrigerator door circuit on the board

Lamp control circuit on the board

Connection on the board

Wiring harness

Lamp connections

Lamp

Presence of magnet on the refrigerator door

TESTING:

General on appliance: switch the appliance on, open the refrigerator door and visually

check that the lamps come on.

Wiring: check for continuity and short circuits; check the connections (connectors and

terminals); check whether voltage is available.

Component: visually check the lamp; direct check of the lamp (powered directly).

A possible cause of incorrect lamp functioning can be the absence or wrong position of

the magnet on the refrigerator door.

Electronic board: carry out a quick visual check of the board (breakages or burnouts,

etc.); check by using a replacement.
