The Cooling Fan Blade is an OEM part for LG microwaves. It circulates airflow around internal components to reduce temperatures during cooking.  

As it operates continuously, the tightly wound coils of the fan motor are prone to degradation and wear over several years of use. Damage to the fan housing can also inhibit proper functioning.

Causes of a bad cooling fan blade include:

• Broken or cracked plastic that unbalances the unit
• Worn down edges that decrease efficiency 
• Accumulated dirt that impedes ventilation

Symptoms of a bad cooling fan blade include:

• Overheating trips from the thermal cut-off  
• Cook times lengthening due to inefficient cooling
• Rattling or vibration noises emanating during operation

This OEM LG replacement ensures balanced airflow and consistent cooling for years of use. It is also compatible with some Kenmore and Sears/Kenmore microwaves.

A direct-replacement power cord assembly that restores a secure electrical connection to the appliance. Replaces a damaged or worn cord to help regain reliable power and reduce risk of arcing or intermittent operation. What it does:

• Provides the appliance's main AC power connection to the household outlet.
• Replaces frayed, cracked, or burned cords that can cause intermittent power or complete loss of power.
• Helps eliminate loose-terminal or plug issues that can cause sparking or a burning smell.
• Ensures proper fit and routing when the correct cord and terminals are used for the appliance.

• One power cord assembly.

• Always disconnect power at the breaker or unplug the appliance before starting work.
• Route the cord away from moving parts and heat sources; secure strain relief or clamp per the appliance cabinet.

This humidity sensor assembly monitors moisture inside the microwave cavity during Sensor Cook and Reheat cycles, allowing the control to automatically adjust time and power. Replacing a failed sensor can restore accurate, reliable sensor-based cooking performance. What it does:

• Detects steam/humidity in the cavity for auto-sensing cook and reheat programs
• Sends feedback to the control board to adjust power levels and cook time
• Failure symptoms include sensor cook not starting, stopping early, "sensor" error messages, or inconsistent results on auto settings

• One humidity sensor assembly

• Unplug the appliance before service; microwaves contain a high-voltage capacitor that can retain a dangerous charge
• Handle the sensor face carefully and keep it clean; route and secure the wire harness as originally

This cooling fan motor spins the internal fan that moves air through the appliance to dissipate heat and protect sensitive components. Replacing a noisy, weak, or seized motor restores proper airflow and dependable operation.

• Drives the cooling fan to circulate cooling air within the cabinet
• Helps prevent overheating and thermal shutdowns of internal parts
• Restores airflow when the original motor is worn, noisy, or not turning
• Typical signs include no fan movement, unusual humming/squealing, reduced airflow, or the unit shutting off from heat

• Disconnect power (and gas, if applicable) before servicing; allow the appliance to cool completely
• Access the motor by removing the appropriate rear/top or control-panel cover for your model
• Note wire orientation; transfer the fan blade and any mounting parts from the original motor if required
• After installation, ensure the fan spins freely and verify proper airflow and quiet operation

The Light Bulb is an OEM part for LG microwaves. It provides illumination inside the microwave oven, allowing users to monitor the cooking process and check the condition of the food without opening the door.

Causes of a bad light bulb can include normal wear and tear, electrical surges, or damage due to impact or overheating. Over time, the filament inside the bulb can burn out, or the bulb itself can become loose or disconnected.

Symptoms of a bad light bulb include:

• The microwave interior light not turning on
• Flickering or dimming of the light
• Intermittent lighting during operation

This OEM LG part is also compatible with Sears/Kenmore models.

This fan assembly replaces the oven/range cooling blower to restore proper airflow and help prevent overheating of control electronics. It's a direct-fit assembly designed to replace a failed or noisy blower unit. What it does:

• Circulates air to cool control components and maintain safe operating temperatures
• Replaces worn or failed blower motor that won't start or runs intermittently
• Restores airflow when the appliance is running hot or control board overheats
• Reduces rattling or grinding noise caused by a damaged fan or housing

• Turn off power to the appliance at the breaker before starting any repairs
• Inspect mounting points and wiring harness for damage; replace connectors if frayed
• Follow OEM service manual for removal and reinstallation torque and routing

The Charcoal Filter is an OEM part for LG microwaves. It plays a crucial role in filtering and removing odors, smoke, and grease particles from the air during cooking. It is constructed with activated charcoal, which has absorbent properties and helps to eliminate cooking odors.

Over time, the charcoal filter can become saturated and less effective in odor removal. It is recommended to replace the charcoal filter periodically to maintain optimal performance and ensure clean and fresh air in your kitchen.

Symptoms of a saturated or clogged charcoal filter may include:

• Lingering cooking odors in the kitchen
• Reduced efficiency in capturing smoke or grease particles
• The presence of visible debris or discoloration on the filter

This OEM LG part can also be used on Kenmore/Sears appliances.
