The Top Load Washer Coupling Assembly is an OEM component specifically designed for LG brand top-loading washing machines. This assembly connects the agitator shaft to the transmission inside the washer, allowing oscillating motions to be transferred through the transmission from the motor. 

Symptoms include:  

• No agitator movement or flickering motions during wash cycles
• Grinding or clicking noises coming from the motor/transmission area
• Leaks or loose fluid from damaged housing components  
• Shaking or instability of the entire washing machine

Causes of a bad coupling assembly can include material failure from ongoing vibration exposure, loosened connection points allowing unwanted play, or cracks/breaks due to heavy impacts.

This genuine hardware washer installs at the specific joint shown in your model's parts diagram. It spreads clamp force and keeps the connection aligned and secure to support smooth operation of the related component. What it does:

• Distributes fastener load and protects mating surfaces from damage
• Maintains proper spacing and alignment within the assembly
• Helps resist loosening from vibration over time
• Clues it may be needed or worn: loose/rattling parts, unusual vibration or noise, or visible wear at the fastener location; on some models, seepage at that joint

• 1 washer

• Disconnect power and turn off water supply before servicing
• Support the assembly, remove the fastener, and install the washer in the same orientation
• Tighten the fastener snugly without overtightening; replace any damaged bolts, nuts, or seals

The balancer assembly mounts to the washer's basket/tub to counterbalance loads during spin. When worn or damaged, it can cause shaking, banging, or out-of-balance errors. Replacing it helps restore smoother, quieter spin performance.

• Stabilizes the basket/tub during acceleration and high-speed spin
• Helps reduce vibration, banging, and washer "walking"
• Can prevent spin cycles from slowing or stopping due to imbalance

• Disconnect power and allow moving parts to stop before servicing
• Access is typically at the top of the tub/basket under the tub ring; remove covers as needed
• Note orientation; seat the assembly evenly and ensure all tabs/fasteners are fully engaged
• After reassembly, run an empty spin test to verify smooth operation

This thermistor assembly monitors water temperature inside the washer tub and relays a precise signal to the control board. Replacing a failed sensor restores accurate temperature sensing and helps prevent cycle errors and performance issues. What it does:

• Measures wash water temperature and sends the signal to the electronic control
• Enables the control to adjust cycle operation based on temperature feedback
• Common failure signs: tE/TE error codes on some models, incorrect temperatures, long cycles, or cycles that won't advance
• Intermittent faults may cause sporadic errors or inconsistent performance

• 1 thermistor assembly

• Disconnect power and shut off water before servicing
• Access location varies by model; the sensor is typically mounted in the outer tub or heater housing
• Unplug the harness, pull the old sensor straight out; seat the new sensor fully and reconnect the harness
• Route wiring away from moving parts; restore power and run a test cycle, checking for proper operation and any leaks around the sensor port

Detergent housing assembly that holds and routes detergent to the washer dispenser, helping ensure proper detergent flow and reducing leaks or dispenser jams. Fits into the dispenser area to replace cracked, warped, or damaged housing components. What it does:

• Houses and channels liquid or powdered detergent into the dispenser and wash chamber
• Restores proper detergent release when the original housing is cracked, broken, or warped
• Helps stop leaks and detergent buildup around the dispenser area
• Works with the dispenser drawer and related seals to maintain correct flow

• Disconnect power and turn off the water supply before starting service
• Use basic hand tools and follow the washer service manual or OEM diagram for disassembly/reassembly
• Inspect and replace any worn seals or gaskets at reassembly to prevent leaks

The Control Board is an OEM component specifically designed for LG front-loading washing machines. Located within the control housing, this printed circuit board directs vital operations like water levels, cycle programming, and temperature regulation. Precise microchip programming optimizes every laundry load.

Symptoms of a bad control board include:  

• Washer failing to initiate cycles or advance phases
• Inability to select desired temperatures, spin speeds, or cycles  
• Erratic sounds, motions, or lights between operations
• Diagnostic error codes appearing on display

Causes of a bad control board can include water damage damaging circuits over time, electrical faults reducing component lifespan, or loose connections inhibiting full communication. Without directing key systems appropriately, the washer cannot efficiently clean clothing and linens.

This LG OEM replacement ensures consistent laundry assistance through long-lasting, dependable performance. Compatible also with Kenmore front-loaders, it provides simple repairs while restoring all functional controls.
