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 is a charcoal filter intended for use with LG microwaves. This charcoal filter removes odors and small particles emitted from foods that would otherwise circulate through the air during the cooking process. It is normal for a charcoal filter to become too dirty to function properly during the normal lifespan of the microwave. When that happens, a replacement filter is required to prevent odors.If strong smells are recognized during the operation of an LG microwave that weren't noticeable before, it's likely the charcoal filter has become clogged or needs to be swapped out with a new one. Replacing the charcoal filter in an LG microwave is a relatively easy task. It is recommended to first disconnect the appliance from the electrical outlet to prevent accidental activation of the device. Wear work gloves for protection. This LG charcoal filter is an authentic OEM replacement part. It is made specifically for LG brand microwaves and fits several different models. It is made of high-quality, durable materials. The LG charcoal filter is recommended to be replaced every six months to one year. It is sold as an individual unit.

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

This replacement lamp socket holds the light bulb and provides a stable electrical connection so your appliance light works reliably. Replace a heat-damaged or loose socket to restore consistent illumination and help prevent flicker, arcing, and premature bulb failure.

• Secures the bulb and connects it to power
• Restores proper interior or work-area lighting
• Addresses flickering, intermittent light, or bulbs failing early from poor contact
• Replaces sockets that are cracked, melted, or discolored

• Disconnect power at the breaker or unplug before servicing
• Allow the area to cool; wear gloves and safety glasses
• Note wire positions and transfer one lead at a time to the new socket
• If servicing a microwave, access only the lamp area per your model instructions; do not open the cabinet—internal components can retain high voltage
