Kenmore Elite 72180839500 microwave/range hood combo Parts

To reset your Kenmore Elite 72180839500 microwave, we recommend doing a simple power reset first: unplug the microwave (or turn off the breaker) for about 1 minute, then restore power and test operation. For control-related issues, use the cancel/clear function described in the owner's manual.

Quick reset options (most common)

• Power reset: Unplug for 60 seconds, then plug back in.
• Stop/Clear reset: Touch STOP/CLEAR to cancel an active cooking program.
• Timer cancel: If the unit will not start because it is acting like a timer, press KITCHEN TIMER, turn the dial to Turn off, then press the dial to cancel.
• Door reset: Open and firmly close the door to ensure it latches.

If the microwave still will not run after resetting

These checks match the most common “won’t start” causes for this model series:

• Confirm the microwave is plugged into a grounded 3-prong outlet.
• Check the household fuse/circuit breaker.
• Make sure the door is fully closed and latched.
• Press START after selecting a cook function.
• Cancel any previous operation by pressing STOP/CLEAR, then try again.

What to look for

What you see	What it usually means	What to do
Display works, won’t start	Door not latched or a mode still active	Close door firmly; press STOP/CLEAR
Acts like a timer	Kitchen timer is running	Cancel timer (Turn off)
Nothing works	No power to unit	Check outlet, breaker, power cord

Why it matters

A “reset” often just clears a stuck selection, cancels the kitchen timer, or restores power after a brief glitch. If the microwave repeatedly loses power or will not start even with correct steps, that points to an electrical supply issue or an internal component problem that needs proper diagnosis.

On the Kenmore Elite 72180839500 microwave/hood combo, the internal line fuse is typically located behind the top vent grille area, near the control compartment where the power cord enters. Access starts by removing the vent grille as shown in the owner's manual.

Quick access overview (what you remove first)

• Unplug the microwave or shut off power at the breaker.
• Remove the screws securing the top vent grille.
• Tip the grille forward, then lift it up and out.
• Look into the control area behind the grille; the fuse is usually in a small fuse holder or clip.
• If you need to remove additional covers, keep track of screw locations for reassembly.

How to confirm the fuse is the problem

A blown internal fuse often happens after a power surge, door switch issue, or shorted component. Check these basics first:

• Outlet has power (test with a lamp or meter).
• House fuse or circuit breaker is not tripped.
• Door closes firmly and latches.
• Unit is not stuck in a timer-only mode (cancel with STOP/CLEAR).

Testing and replacement basics

We recommend testing the fuse with a meter for continuity before replacing it.

Step	What to do	What you’re looking for
1	Disconnect power	No voltage present
2	Remove vent grille	Access to control area
3	Locate fuse holder/clip	Glass or ceramic fuse
4	Meter test (continuity)	Continuity = good; open = blown
5	Replace with same rating	Correct amp/voltage type

Why it matters

Microwaves contain high-voltage components that can store dangerous energy even when unplugged. If you are not fully comfortable working around the control compartment and wiring, we recommend using a qualified technician and using the wiring and safety guidance in the owner's manual.

Yes. The Kenmore Elite 72180839500 is positioned as a premium (high-end) microwave/hood combo within the Kenmore lineup, typically offering stronger feature sets and a more upscale build than standard Kenmore models. For day-to-day use, it is designed to deliver dependable cooking performance and ventilation when installed and maintained correctly (see the owner's manual).

What “high end” means for this model

For a microwave/hood combo like the Kenmore Elite 72180839500, “high end” usually comes down to a mix of performance, convenience features, and serviceability.

Common high-end expectations include:

• More consistent heating and cooking results (turntable-based cooking system)
• Better ventilation support for a range top (grease filtration and ducting options)
• More sensors and automatic cooking features (varies by configuration)
• Better long-term maintainability because key components are replaceable

Parts that support long-term performance

If your goal is to keep this microwave running like a premium unit, these are some of the most important service parts commonly tied to heating, door safety, and ventilation:

• Heating circuit components: microwave magnetron 6324W1A001L, high-voltage diode 6021W3B001V, goldstar microwave high-voltage capacitor 0CZZW1H004C
• Door safety and operation: microwave door latch spring 4970WRA001G, microwave micro-switch 3B73361E
• Venting upkeep: grease filter 5230W1A012E, lg microwave charcoal filter 5230W1A003A

Quick comparison: premium vs standard expectations

Area	Premium expectation	What to do to keep it there
Heating	Fast, even cooking	Keep cavity clean; address weak heat early (magnetron/diode/capacitor)
Venting	Better smoke and odor capture	Clean or replace grease and charcoal filters on schedule
Fit and finish	More solid feel	Avoid slamming the door; replace worn latch or switch parts

Why it matters

A “high-end” microwave/hood combo only feels premium when it heats correctly, vents well, and the door interlocks work smoothly. Staying on top of filters and fixing early symptoms (weak heat, arcing, door not closing cleanly) protects performance and helps prevent repeat failures.

The most common problems we see with the Kenmore Elite 72180839500 microwave/hood combo are “won’t start,” “no heat,” and door-related issues (won’t latch or stops mid-cycle). Many of these trace back to power supply issues, door interlock switching, or a failed high-voltage heating component.

Most common symptoms (and what they usually point to)

• Microwave does not work at all: tripped breaker, blown house fuse, or unplugged cord
• Microwave will not run: door not firmly closed and latched, START not pressed, or a prior cycle still active (STOP/CLEAR needed)
• Runs but does not heat: high-voltage circuit failure (magnetron, diode, capacitor)
• Stops when you close the door or won’t start unless you lift/push the door: worn door latch parts or a failing interlock switch
• Turntable not turning: failed turntable motor or obstruction

Quick checks we recommend first (no tools)

1. Confirm the outlet has power and the cord is fully seated.
2. Close the door firmly; the door must latch completely for safe operation.
3. Press STOP/CLEAR to cancel any previous operation, then try a simple 30-second heat test with a cup of water.
4. Check your home breaker or fuse.
5. If the unit is damaged (bent door, broken seal, broken glass), stop using it and have it serviced.

Parts that commonly fix “no heat” or “won’t start”

Symptom	Common part area	Example part for this model
Runs but no heat	High-voltage heating circuit	Microwave magnetron 6324W1A001L
Runs but no heat, burning smell or arcing sounds	High-voltage diode/capacitor	High-voltage diode 6021W3B001V, goldstar microwave high-voltage capacitor 0CZZW1H004C
Won’t start, door issues	Door interlock switching	Microwave door interlock switch 3B73361E

Why it matters

This model uses safety interlocks to prevent operation with the door open. If the door, latch, or interlock switches are misaligned or failing, the microwave can refuse to run or behave intermittently. Heating failures often involve high voltage components, which require careful, qualified service.

Safety note for this model

We follow the installation and safety guidance for the 72180839500: do not operate the microwave with a damaged door or defeated interlocks, and do not attempt internal adjustments or repairs that require checking for microwave leakage after service. See the installation guide for the key safety warnings and grounding requirements.

The Kenmore Elite 72180839500 microwave/hood combo has a 1.8 cu. ft. interior capacity. You can confirm the capacity and other key specs (like cutout and venting requirements) in the owner's manual.

How to verify capacity on the appliance

Use the model’s documentation and rating label so you match the correct configuration.

• Check the specifications/features section in the manual
• Match the full model number on the rating label (typically inside the door area)
• Use the capacity to choose cookware that rotates freely on the glass tray
• If you are planning an over-the-range replacement, compare cabinet clearance and venting style

Why cubic feet matters

Capacity affects what fits on the turntable and how practical the microwave is for everyday reheating, sensor cook, and defrost.

Capacity	What it usually fits	Common use
1.6 to 1.7 cu. ft.	Dinner plates, medium bowls	Basic reheating
1.8 cu. ft.	Larger plates, medium casseroles	Most households
2.0+ cu. ft.	Larger cookware	Frequent cooking, big portions

Related parts that affect usable space (not the rated capacity)

Interior capacity is fixed, but these parts affect how well you can use that space day to day.

• If the tray stops rotating, check the microwave turntable motor 6549W1S018C
• If the door does not close smoothly, inspect the microwave door latch spring 4970WRA001G
• If the cooktop area is dim, replace the microwave light bulb 383EW1A077B
