Parts for Kenmore 721.83547020 (72183547020, 721 83547020): Controller Parts

The TEMPLATE is an OEM part for LG microwaves. It is the outer casing and control panel covering that defines the microwave's design and aesthetics.  

The causes of a bad template can include cracks, dents, or damage to the outer surface from impacts or normal wear over time. Heat and humidity fluctuations can also cause template materials to degrade.

Symptoms of a bad template include:

• Cracks or breaks in the template material
• Loose, misaligned, or damaged control panel or display  
• Yellowing, warping, or discoloration of plastics
• Openings or gaps that compromise the microwave structure

This genuine OEM LG replacement part restores the microwave's appearance and protects internal components. It is also compatible with some Kenmore and Sears microwaves
 

A Tap-Tite binding-head screw used to fasten appliance panels and components where a self-tapping metal thread is required. Replaces missing or damaged fasteners to restore secure assembly and reduce vibration or rattling. What it does:

• Creates its own mating thread in thin sheet metal for a secure hold without a nut.
• Holds panels, brackets, and trim in place to prevent looseness or movement.
• Commonly used where stripped, missing, or broken screws cause rattling, misalignment, or parts that won't stay attached.
• Compatible with standard screwdrivers or nut drivers sized to the binding-head.

• Disconnect power and unplug the appliance before working on it.
• Use the correct driver bit to avoid cam-out or head damage.
• Start straight and apply steady pressure; avoid overtightening to prevent stripping the formed threads.
• If the original hole is badly damaged, assess for repair or use of a larger fastener as needed.

Replacement screw for securing panels, brackets, and internal components. Restores tight fit and proper alignment when original hardware is stripped or missing.

This customized screw fastens specific panels, brackets, or internal components in LG appliances. Replacing a missing or stripped fastener restores a secure fit and helps reduce vibration, rattling, and premature wear. What it does:

• Restores proper fit when the original screw is lost, damaged, or stripped
• Helps reduce vibration and rattling from loose components
• Maintains alignment to support correct operation of the assembly

• Includes: One screw

• Disconnect power and, if applicable, shut off water and gas supplies before servicing
• Match length and thread to the original; start by hand to avoid cross-threading
• Use the correct driver size and tighten snugly without over-torquing
• Inspect and replace any damaged clips, inserts, or mating threads before reassembly

This is a metal plate that covers the vent duct area on an over-the-range microwave, directing airflow from the ventilation system and protecting internal components. It helps channel exhaust air properly when the microwave's vent fan is in use. Replace this plate if it is dented, corroded, or missing, as a damaged cover can reduce ventilation efficiency and allow grease or debris to enter internal areas.

This is a glass or plastic lens cover that sits over the interior light bulb inside the microwave. It protects the light bulb from grease, food splatter, and heat while allowing light to illuminate the cooking cavity. Replace this lens if it is cracked, cloudy, discolored, or missing, which can leave the bulb exposed to damage and reduce interior visibility.

This is a metal cooking rack designed to sit inside the microwave oven cavity, providing a second level for heating multiple items at once. It allows for more even cooking by elevating food closer to the center of the microwave's energy field. Replace this rack if it is bent, has damaged feet or support clips, or if the protective coating is chipped or worn, which can cause arcing during use.

Fix a microwave door that won't close or latch properly. This door latch holder secures the latch assembly for reliable door alignment and operation.

This assembly includes the door latch housing and interlock switches that detect whether the microwave door is properly closed. It ensures the microwave only operates when the door is securely latched, serving as a critical safety component. Replace this assembly if the microwave won't start, runs with the door open, blows fuses repeatedly, or if the door latch mechanism feels loose or broken.

Fix a microwave that won't start or runs with the door open. This door interlock switch ensures safe operation by detecting when the door is fully closed.

This is a micro switch that detects whether the microwave door is properly closed and latched. It is part of the safety interlock system that prevents the microwave from operating with the door open. Replace this switch if the microwave does not start when the door is shut, runs with the door open, blows a fuse when the door closes, or stops mid-cycle intermittently.

Microwave won't heat? A failing high-voltage capacitor disrupts the heating circuit. This part stores electrical energy for consistent operation.

The Time Delay Fuse is an OEM part for LG microwaves. This fuse provides a safety mechanism by delaying the flow of electricity, protecting the microwave's electrical components from power surges and ensuring the appliance operates safely. It helps to prevent immediate damage in the event of a power surge or electrical fault, thus prolonging the lifespan of the microwave.

Over time, the time delay fuse can become damaged due to electrical surges, wear and tear, or faulty connections. If the fuse blows, it can disrupt the microwave’s ability to function correctly.

Symptoms of a bad time delay fuse include:

• The microwave not turning on
• No response from the microwave control panel
• The microwave stopping unexpectedly during operation
• Electrical issues or blown circuits in the microwave

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

This thermostat is a temperature-sensitive safety switch used in LG microwaves. It monitors internal temperature and opens the circuit when overheating is detected to help protect components from heat damage.

• Monitors temperature at its mounting location inside the microwave
• Opens on overtemperature to interrupt power for safety
• Depending on model/location, a failed or open thermostat can cause no heat, the unit shutting off mid-cycle, or no power until it cools
• Helps prevent damage to the magnetron, cavity, and wiring due to overheating

• Unplug the microwave before service; the high-voltage capacitor can retain a dangerous charge
• Note wire positions, remove mounting screws, and install the new thermostat flat against the surface for proper heat sensing
• Reassemble and test; ensure vents and filters are clear to maintain proper airflow and prevent future overheating

This box-style film capacitor helps stabilize and filter voltage in the appliance's control/power circuitry, protecting electronics from spikes and electrical noise for more reliable operation. What it does

• Smooths and filters voltage to reduce electrical noise and transient spikes.
• Helps ensure stable operation of control boards and motor drives.
• A failing capacitor can cause intermittent operation, control errors, or failure to start.
• Commonly used where low-loss, stable capacitance is required for power or signal circuits.

• Disconnect power to the appliance before servicing.
• Discharge the capacitor fully before touching terminals to avoid shock.
• Inspect mounting and wiring; replace with identical type and polarity/orientation if required.
