Kenmore Microwave 721.80592402 (72180592402, 721 80592402) Parts

This canopy resistor regulates current to a range-hood or canopy fan circuit to help the blower run at the correct speeds. Replacing a failing resistor can restore proper fan speed control and stop intermittent operation. What it does:

• Controls electrical resistance in the canopy/blower circuit to help regulate fan speeds.
• Helps prevent the motor from running only on a single speed or from failing to start at selected speeds.
• Can cause symptoms such as inconsistent fan speeds, no response from speed controls, or occasional fan cutoff.
• Works with the hood's wiring and control switch to deliver the correct voltage to the fan motor.

• Disconnect power to the appliance before accessing the canopy or electrical connections.
• Inspect wiring and connectors for heat damage or corrosion; replace harness or terminals if damaged.

This is a truss-head tapping screw used to secure trim, panels, and small assemblies on compatible LG appliances. It provides a low-profile, wide-bearing head that helps hold parts flush and resist pull-through. What it does:

• Fastens plastic and sheet-metal components where a self-tapping thread is needed
• Truss head spreads load to prevent damage to soft or thin materials
• Helps secure control panels, brackets, or trim pieces that require a low-profile head
• Common replacement when original mounting screws are missing, stripped, or corroded

• One truss-head tapping screw

• Use the correct screwdriver bit and moderate torque to avoid stripping the screw or workpiece
• Start threading straight and let the screw form threads without forcing at an angle
• Disconnect power and follow appliance-specific service safety procedures before working internally
• Replace any damaged mating threads or clips for a secure fit

This replacement mounting screw secures panels and small appliance components to restore proper fit and prevent vibration or loose parts. A simple, direct replacement when the original fastener is missing or damaged. What it does:

• Secures panels, brackets, or small assemblies to keep parts aligned
• Stops rattling or vibration caused by loose or missing screws
• Restores normal fit where a stripped or corroded screw failed
• Matches the OEM fastener form for a correct, long-lasting fit

• Unplug the appliance or disconnect power before servicing
• Use the correct driver to avoid stripping the head
• Thread carefully and do not overtighten to prevent damage to threads or housing

The Turntable Coupler is an OEM part for LG microwaves. This coupler connects the motor to the turntable, enabling the rotation of the glass tray during the cooking process. 

Causes of a bad turntable coupler can include wear and tear from regular use, cracks or breaks due to the weight of heavy dishes, or damage from accidental impact. 

Symptoms of a bad turntable coupler include:

• The glass tray not rotating during operation
• Uneven heating or cooking of food
• Unusual noises from the turntable area
• Visible damage or wear on the coupler

This OEM LG part is also compatible with some Kenmore models.

Color: brown. Measures about 10 inches in diameter.

Inner plastic door film covers the holes in the inner door frame.

This turntable motor drives your microwave's glass tray, rotating food for more even heating. Replacing a failing motor restores proper tray movement and helps reduce cold spots during cooking. What it does:

• Rotates the glass tray via the turntable coupler during cook cycles
• Helps promote even heating by keeping food moving
• Addresses symptoms such as the tray not turning, intermittent rotation, or grinding/clicking noises from beneath the cavity
• Useful check: ensure the roller ring and coupler aren't damaged or obstructed

• 1 turntable motor

• Disconnect power; microwaves contain high-voltage components that can retain a charge
• Typically accessed from the unit's bottom panel; remove the cover to reach the motor
• Move the two wires and mounting screws from the old motor to the new one; align the shaft with the coupler
• After reassembly, confirm the tray sits correctly on the roller ring and spins freely

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 door frame assembly replaces the appliance's outer door trim and support to restore proper door fit and protect the inner door components. Ideal when the door frame is cracked, bent, or no longer secures the door evenly. What it does:

• Restores the outer door trim and structural support so the door closes and latches properly.
• Protects the door glass and inner components from impact and moisture intrusion.
• Helps eliminate gaps or misalignment that can cause rattling, air leaks, or difficulty closing the door.
• Matches the OEM form for a direct replacement when the original frame is damaged.

• Disconnect power and unplug the appliance before starting any repair.
• Remove the existing door trim/frame by loosening the retaining screws or clips; handle any glass carefully.
• Check door alignment and seal after installation; adjust hinge or strike as needed for proper fit.
• If the assembly has bonded or sealed components, consider replacing any associated gasket or fasteners if damaged.

This is a shelf, or warming rack, intended for use with microwaves. This shelf allows a place to set the items being warmed. With regular use, the shelf may get damaged. The shelf could also get misplaced. If there is a missing or broken shelf, the part should be replaced with a genuine OEM replacement part to continue the efficient performance of the appliance.Visual inspection of the shelf inside the microwave will quickly determine if the part is missing or broken. Replacing a damaged or misplaced shelf is a quick and straightforward process. Remove the old shelf and slide the new shelf into the proper position. Continue regular use of the appliance. Make sure that the metal shelf is not touching any part of the appliance on the inside, including the sides, top, or bottom.This shelf is an authentic OEM replacement part. It is made of high-quality, durable materials. The shelf is sourced directly from the manufacturer. This shelf for microwaves is compatible with several different models of appliances. It can be installed in many brands of microwaves, including devices produced by Kenmore, LG, Amana, and General Electric.

Size: 5 inches x 7 3/4 inches.
