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.
 

Color: blue. It measures about 3 inches wide by 1 inch high.

This safety interlock switch assembly controls the microwave's door-sensing circuit, allowing the oven to run only when the door is fully latched. Replacing a worn assembly restores safe, consistent start/stop behavior. What it does:

• Detects door open/closed status and completes the safety interlock circuit
• Prevents operation with the door open; allows cooking only when latches engage
• Helps address: won't start unless pressing on the door, shuts off when the door is jostled, "Door"/"Open/Close" error
• Also corrects interior light or fan staying on/off incorrectly due to a failed interlock switch

• One safety switch assembly

• Disconnect power; microwaves contain a high-voltage capacitor that can retain a dangerous charge even unplugged
• Remove the outer cabinet to access the door-latch/interlock area
• Note switch orientation and wire locations; transfer connectors one at a time and secure the assembly
• After reassembly, confirm smooth door closure and test for proper start/stop operation

Fix unresponsive buttons, error codes, or cycles that won't start. This main control board coordinates all dishwasher functions. Moderate DIY repair.

The Pump Motor Assembly is an OEM component specifically designed for LG dishwashers. It houses both the wash and drain pump motors integrated within a singular assembly. 

These motors work together to efficiently circulate water through spray arms during wash cycles for optimized cleaning performance. They also help drain dirty water at the end of each cycle, ensuring dishes are thoroughly rinsed.  

Symptoms of a bad pump motor assembly include:

• Inadequate or incomplete wash and rinse performances
• Water failing to drain fully after cycles
• Leaks occurring due to ineffective pumps   
• Abnormal sounds from the motor during the operation

Causes can include normal wear over time, failures in motor electronic components, or damage from foreign debris. 

Replacing the pump motor assembly with this genuine OEM LG part restores optimized wash and rinse functions. It is also compatible with Sears/Kenmore dishwashers.

Channels wastewater from your dishwasher to the household drain. Replace if cracked, kinked, clogged, or leaking to restore proper drainage during cycles.

This refrigerator damper assembly opens and closes the air passage between the freezer and fresh food sections. Replacing a sticking or broken damper restores proper airflow and more stable temperatures, helping resolve warm spots or food freezing in the refrigerator.

• Regulates cold-air flow from the freezer into the refrigerator to maintain set temperatures
• Operates a flap within the air duct under control of the appliance's control system
• Helps reduce temperature fluctuations and improve overall cooling performance

• Disconnect power before servicing
• Access from inside the fresh food compartment; remove shelves and the damper/duct cover
• Remove mounting screws and disconnect the wire harness; transfer any foam seals or clips from the old unit if needed
• Seat the gasket evenly to prevent air leaks and route wiring away from the moving flap

Fixes inconsistent cleaning and improper cycle timing caused by inaccurate water clarity detection. Measures soil level in wash water for optimal performance.

This roller assembly supports the dryer drum and lets it turn smoothly to help clothes tumble evenly. Replacing a worn roller restores proper drum rotation and reduces noise and wobble during use. What it does:

• Supports the dryer drum on a stationary shaft so the drum spins freely
• Reduces squeaking, grinding, or scraping noises from a worn roller
• Helps prevent drum wobble and uneven tumbling that can affect drying
• Restores smooth rotation for improved operation and reduced wear on other components

• One roller assembly

• Disconnect power before starting and remove the dryer back panel to access the drum rollers
• Inspect adjacent parts (belt, glides, rear bearing) and replace if worn to avoid repeat failures
• Reinstall drum and panels carefully, ensuring the roller rides squarely on the shaft and the drum is aligned
• Test spin by hand before reconnecting power and running a short cycle to confirm quiet, smooth operation
