Troubleshooting

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.

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).

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).
