Parts for Lg LMV1683ST / 00: Installation Parts

The Magnetron Thermostat is an OEM part for LG microwaves and built-in ranges. Its primary function is to monitor the temperature and ensure that it remains within a safe operating range. If the temperature exceeds the preset limit, the thermostat will interrupt the power supply to the magnetron, preventing overheating and potential damage.

Causes of a faulty magnetron thermostat can include electrical malfunctions, component failures, or physical damage. These factors can result in issues such as erratic heating, microwave not heating properly, or the appliance shutting off unexpectedly.

Symptoms of a bad magnetron thermostat may include:

• Microwave not heating food evenly or at all
• Inconsistent or weak heating performance
• Microwave shutting off or displaying error codes related to temperature issues

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

The Mounting Plate is an OEM part for LG microwaves. This part is designed to mount and stabilize the microwave over the range, ensuring it is safely anchored in its designated space. The mounting plate serves as an interface between the microwave and the wall or cabinet, distributing the weight evenly and providing a firm foundation for the appliance.

Causes of a bad Mounting Plate can stem from improper installation, which may lead to undue stress and eventual warping or weakening of the material.

Symptoms of a bad Mounting Plate include:

• Loose microwave unit
• Difficulty in aligning or installing the microwave 
• Visible signs of wear, rust, or damage on the plate

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

This factory installation kit provides the hardware needed to securely mount a compatible microwave. It restores a safe, level install when the original bracket or fasteners are missing, damaged, or after a relocation. What it does

• Secures the microwave to wall studs and upper cabinet per factory specifications
• Helps maintain proper clearances and ventilation paths during installation
• Replaces lost, stripped, or damaged mounting hardware
• Addresses issues like a loose/sagging unit or an incomplete installation

• One installation kit assembly

• Disconnect power and have two people support the appliance during removal/installation
• Locate and fasten into wall studs; use hardware appropriate for your wall/cabinet materials
• Follow the model-specific installation instructions and verify level and clearances before tightening
• If venting externally, align ducting and transitions before final mounting

The Damper Bracket is an OEM component for LG microwaves. Located inside the microwave cavity above the wave stirrer, this bracket holds the position of the damper assembly that helps distribute heat evenly during cooking. The bracket measures approximately 12” by 5”.

Symptoms of a bad damper bracket can include:  

• Hot or cold spots developing within the microwave cavity
• Looseness in the damper assembly fit
• Reduced heat circulation leading to uneven cooking

Causes typically consist of cracking over long-term heat exposure. Repeated opening/closing of the damper may also weaken attachment points on the bracket.

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

The Damper is an OEM component for LG microwaves. Located within the cooking cavity, it regulates airflow and safely vents steam escaping heated foods. 

Causes of a faulty damper can involve standard wear and exposure accepting steam and condensation release. Food or liquid particles drying within tracks also threaten eventual adhesion issues restricting travel if left unaddressed between cleanings.

Symptoms of a damaged or defective damper include:

• Inability to adequately vent excess moisture from heating  
• Potential messes spilling beyond the microwave frame  
• Grating sounds or squeaks emitting during cooking
• Flaps possibly stuck inhibiting steam circulation 

This damper is also compatible with Kenmore microwaves as well.
