To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.
WARNING
!
Testing Lock Motor
With the Molex connector removed from the
P12 board connection, use an ohmeter to
measure resistance between the red wire
(L2) on the line break relay and the black/
white wire at P12. The resistance should be
approximately 12.5K ohms. If no resistance
is read, remove the latch motor to repair/
replace (Follow the latch motor disassembly
procedure).
Testing Latch Switches
To check the latch switches, access the
control board and unplug the P15 Molex plug.
With the door in the unlocked position, you
should read continuity (0 ohms) between the
brown wire and the blue/white wires, and
read infinite ohms (∞) between the brown and
orange wires. If your readings are incorrect
or reversed, remove the latch and inspect,
repair/replace (follow latch motor disassembly
procedure).
