on BSD 1.4 and check the harness for an open circuit. If the
harness is good, replace the Drawer Interlock Switch
Replace the AC Driver PWB
Go to

If the fault code is present and can not be cleared, replace the IOT Drive PWB
fault code is not present and is occurring intermittently, go to
harness for an intermittent open circuit. If the harness is OK, go to
check the wire for an intermittent open or short circuit. If the harness is good, replace the
