Product Electronic Control System - Whirlpool WBM35LW Service Manual

When the door is closed, the magnet is on the Interface Board, which informs the Potency Module causing
the corresponding Lamp to remain OFF. When the door is opened, the magnet stays away from the
Interface Board and the Lamp turns ON. The technician can test the activation system by using a round
magnet with approximately 20 mm in diameter and 5 mm in height (preferably).
The WRM34, WBM35 models are fitted with only one lamp on the Refrigerator Compartment, but their
activation system is the same of the others models
.
