This dishwasher sensor assembly contains the thermistor that monitors wash-water temperature and sends readings to the control. Replacing a faulty sensor restores accurate heating and cycle timing for consistent cleaning and to prevent temperature-related interruptions. What it does:

• Measures wash-water temperature via an NTC thermistor
• Sends a resistance signal to the control to manage heater operation and cycle timing
• Helps maintain target temperatures for proper cleaning performance
• Common failure symptoms include no heat or overheating, long/short cycles, temperature-related errors, or poor cleaning/drying

• Disconnect power at the breaker and shut off water before servicing
• Access the sump area from the bottom; you may need to pull the dishwasher forward for clearance
• Expect some residual water—protect the area with towels
• Seat the sensor fully in the sump opening, reconnect the harness, and run a test cycle to check for leaks and proper heating

Fix a dishwasher door that won't stay shut or cycles that won't start. This door latch and lock assembly restores secure closure and cycle operation.

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.
 

Fix dishwasher leaks from the bottom or poor spray action with a new sump and motor assembly. Includes circulation motor, drain pump, and gasket.

Connects household water supply to your dishwasher. Replace if hose is kinked, cracked, dry-rotted, or leaking at connections. Installs at bottom.

Mounts over the dishwasher's drying fan vent opening to shield the blower and direct airflow into the tub. Replace if cracked, damaged, or missing.

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.

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

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

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.

Creates a watertight seal to prevent leaks in your dishwasher. Replace when worn or cracked to stop water damage. Confirm fit with your model number.

Replace cracked or missing dishwasher protective cover to shield internal components from dust and debris. Restores secure enclosure for wiring and sensors.

This is a common fastening nut used to secure panels, trim, or components on compatible LG appliances. It provides a simple, reliable way to hold mating parts in place and restore proper fit and function. What it does

• Secures panels, brackets, or hardware to prevent movement or vibration
• Stops rattling or loose parts caused by a missing or worn nut
• Restores proper alignment when replacing damaged or stripped fasteners
• Works where a standard threaded nut is required for reassembly

• One common nut as pictured

• Disconnect power and water before servicing the appliance
• Use the properly sized wrench or socket to avoid rounding the nut
• Do not overtighten; tighten until snug and secure per OEM torque guidance
• Replace like-for-like—thread size and type match the original

This clamp secures hoses or wiring to the appliance chassis to prevent movement, chafing, and vibration-related wear. It helps keep connections stable so hoses and wires stay in place during normal use. What it does:

• Holds water, drain or vent hoses in position to reduce strain and prevent rubbing
• Keeps wiring harnesses routed and fastened to avoid chafing or accidental disconnection
• Reduces vibration-related noise caused by loose hoses or wires
• Helps prevent hose kinks and unintended movement that can lead to leaks or intermittent electrical issues

• One clamp

• Disconnect power to the appliance before servicing; shut off water supply if working with water lines
• Remove panels as needed to access the hose or wiring route, then replace the clamp in the same orientation
• Use appropriate pliers or a screwdriver if required; do not overtighten or deform the hose or wiring
• If the original clamp was secured with a fastener, retain and reuse it only if undamaged; replace any stripped or broken hardware
