This temperature-sensing safety switch monitors heat inside the microwave and opens or closes its circuit at a set point. Replacing a failed thermostat helps protect the unit from overheating and restores proper fan or heating control. What it does:

• Monitors surface temperature where it is mounted (cavity, duct, or component)
• Opens/closes its electrical circuit at a specific threshold to prevent overheating
• Can interrupt power to heating components or signal the exhaust fan, depending on design
• Symptoms can include: unit shuts off until it cools, runs but won't heat, exhaust fan won't auto-cycle or runs constantly

• Unplug the microwave; if over-the-range, remove it safely from the cabinet
• Discharge the high-voltage capacitor before servicing
• Note wire positions and transfer one lead at a time; ensure tight connections
• Mount firmly and flush to the original location/bracket for proper thermal contact

A high-voltage capacitor for the appliance's high-voltage circuit that stores and releases electrical energy to support proper heating operation. Replacing a failing capacitor can restore consistent heating and prevent related electrical faults. What it does:

• Stores and delivers high-voltage energy used by the magnetron/ high-voltage assembly to generate heat.
• Failure may cause no-heat or weak-heat conditions in the oven.
• Faulty capacitors can contribute to arcing, loud humming, or blown high-voltage fuses.
• Works as part of the HV circuit; not a user-serviceable low-voltage control.

• High-voltage components can hold a dangerous charge—disconnect power and discharge the capacitor before servicing.
• Use insulated tools and avoid touching terminals; verify proper operation with appropriate test equipment.

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 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.
