Freezer Drawer Switch; Freezer Leds - GE GYE18JBL Technical Service Manual

Freezer Drawer Switch

The freezer drawer switch is an AC volt switch
that has Normally Closed contacts (N.C.). The
switch is actuated by the drawer front to tell the
main board to turn the freezer LEDs on or off.
Freezer Drawer Switch Diagnosing
When the drawer is opened, the switch contacts
are closed allowing 120 VAC to travel to the main
board. When closed, the drawer front engages
the switch to open the switch contacts, breaking
the 120 VAC circuit to the main board.
Switch Not Pressed (Drawer Open)
J7 on Main Board
• Pin 7 (red) to pin 9 (orange): 120 VAC
Switch Pressed (Drawer Closed)
J7 on Main Board

• J14 pin 4 (white/silver) - J3 pin 5 (pink): 2-5
VDC (switched voltage, see NOTE)
Left LED Three Pin Connector:
• Red/silver - blue: 13 VDC (constant voltage)
• Pink - blue: 2-5 VDC (switched voltage, see
NOTE)
Right LED Main Board Connections:
• J14 pin 4 (white/silver) - J4 pin 2 (red/
yellow): 13 VDC
• J14 pin 4 (white/silver) - J3 pin 5 (pink): 2-5
VDC (switched voltage, see NOTE)
Right LED Three Pin Connector:
• Red/yellow - white/silver: 13 VDC (constant
voltage)
• Pink - white/silver: 2-5 VDC (switched
voltage, see NOTE)
NOTE: When the freezer drawer is opened, the
