Food Compartment Lamp Switch
The reed relay switch that turns the fresh food
compartment light on and off is an integral component
of the optical control display board circuitry.
Lamp Switch Operation
The magnetic pull from a permanent magnet located
underneath the top door trim maintains the switch
contacts open (light off) when the door is fully closed.
Opening the door breaks the magnetic pull, which in
turn causes the switch contacts close (light on).
Lamp Switch Testing Procedure
1. Slide a magnetic screwdriver tip or a small magnet
on the underside of the optical control assembly
as shown in the figure above.
2. Check the food compartment light as the
screwdriver tip is moved under the display, the
light:
a. should turn off when the magnetic screwdriver tip
or magnet passes under the optical control
assembly.
b. turn on when the magnetic screwdriver tip or
magnet is distanced from the underside of the
optical control assembly.
3. If the light does not turn off when the magnet
passes under the optical control display, replace
the optical control display assembly.
Before beginning this procedure make sure:
■
Light/thermistor connector and wire harness connector are fully engaged and locked.
