The Micro Switch is an OEM part for LG dishwashers. It plays a crucial role in detecting when the door is securely closed prior to starting a cycle. This important safety feature prevents accidental exposure to hot water, detergent, and chemicals.
Causes of a bad micro switch include degradation from years of repeated use, debris interfering with mechanisms, or damage from attempts to force or slam the dishwasher door closed.
Symptoms of a bad micro switch include:
- Cycles failing to start despite a closed door
- Hot water or steam visible escaping when running
- The dishwasher not detecting the closed door position
- Error codes displayed related to door position sensors
This OEM LG part is also compatible with Sears/Kenmore. Replacing only when truly faulty helps ensure safe and reliable dishwasher function.
