1. Check the membrane wire harness to make sure it is
properly connected with PCB.
Shorted Key 2. Disconnect the membrane wire harness. Check the
-SE- harness, Membrane and PCB for short circuits.
3. If there is not a problem with connector on main PCB and
membrane harness, replace the PCB.

1. Disconnect electrical power to the range. Remove the
rear cover panel. Make sure the wiring harness is properly
connected to the motorized door lock assembly.
2. Check motorized door lock assembly for proper operating
