The door interlocks are a safety feature; a latch fault disables the unit entirely.

Inspect the Latch Hooks

The plastic hooks on the door can crack or stick.

Fix: Examine them for damage; a broken latch assembly should be replaced.

Debris in the latch slots stops the hooks from engaging.

Fix: Clean out the recesses on the cabinet.

Misaligned interlock switches read the door as open.

Fix: A technician realigns or replaces the switch stack.
