Door switch error

Check door for obstructions preventing full closure
Test door switch continuity — should toggle when door is opened/closed
Inspect wiring harness from door switch to CCU for damage
If switch tests good but error persists, the CCU door switch input has failed
Pro Diagnostic Tip
The 110-series Kenmore is Whirlpool underneath, and this code means the CCU never sees the door-closed signal — which points at wiring far more often than the switch. Ohm the run from the switch back to the board first; a strike that sits a hair off can also miss the plunger, so check door alignment before ordering parts.
