How many cubic feet is a Kenmore Model 72180412500 microwave?
The Kenmore microwave/hood combo model 72180412500 has a capacity of about 1.7 cubic feet. Use this capacity when comparing over-the-range fit, cooking space, and replacement options for your kitchen setup.
Where to confirm capacity and other specs
We recommend checking the model documentation for the full spec list (capacity, exterior dimensions, venting options, and electrical requirements).
- Look in the 72180412500 owner's manual for the model overview and feature details
- Use the 72180412500 installation guide for cabinet cutout, mounting, and venting requirements
- Match the full model number from the rating label before ordering parts
- If you are replacing an older unit, compare both capacity and outside width/height/depth
Why capacity matters for an over-the-range microwave
Capacity (cubic feet) tells you the usable cooking space inside the cavity, but it does not guarantee the same exterior size. Two 1.7 cu. ft. microwaves can mount differently depending on the mounting plate and vent damper layout.
Quick comparison: what to use capacity for
| What you are doing | Capacity helps with | What you also need |
|---|---|---|
| Replacing the microwave | Interior cooking space | Exterior dimensions and mounting/venting pattern |
| Choosing cookware | Bowl and plate clearance | Turntable diameter and rack use |
| Troubleshooting heating complaints | Not much | Heating system parts and airflow |
Related parts and fit notes
If you are planning a repair while you compare models, use your exact model number (72180412500) to ensure part compatibility.
- Heating issues often involve high-voltage components such as the microwave magnetron 2B71165R
- Door closing and safety interlocks can involve a door interlock switch
- Venting performance can be affected by the vent damper door and grease filter condition
Why it matters
Using the correct capacity helps you pick a microwave that feels the same in daily use, while the manual and installation guide help you avoid mounting or venting surprises.

Where is the fuse on a Kenmore microwave model 72180412500?
On the Kenmore 72180412500 microwave/hood combo, the fuse is mounted on the internal line-power circuit near where the power cord enters the unit, behind the control panel and grille area. Use the 72180412500 installation guide to identify access points and mounting locations before you open the cabinet.
What to check first (before accessing the fuse)
- Unplug the microwave or switch off the breaker; confirm the display is off.
- If it is an over-the-range unit, support the microwave properly before loosening any mounting hardware.
- Verify the outlet has power (try a small lamp or meter).
- Check the house breaker or GFCI if the microwave is completely dead.
- If the unit died right after pressing Start or closing the door, suspect a door switch or fuse issue.
Typical fuse location on this style of Kenmore microwave
Most Kenmore microwave/hood combos place the ceramic fuse:
- Behind the top grille and/or control panel area
- On or near the noise filter/line filter board
- Close to the power cord connection and wiring harness
Because internal layouts vary by production series, we use the model-specific diagrams and access steps in the 72180412500 owner’s manual to match the fuse position to your exact build.
Parts that commonly relate to a blown fuse symptom
A blown fuse is often triggered by another fault. These model-matched parts are common suspects:
| Symptom | Common related part | Sears PartsDirect part ID |
|---|---|---|
| Dead display, no interior light | Microwave fuse | 3B74133Q |
| Blows fuse when door opens/closes | Door interlock switch | 6600W1K001R or 6600W1K001Q |
| Runs but does not heat (not a fuse issue in many cases) | Magnetron or high-voltage parts | 2B71165R, 6021W3B001V, 0CZZW1H004B |
Why it matters
Microwave fuses protect the unit from unsafe current draw. If you replace a fuse without correcting the underlying cause (like a failing door interlock switch), the new fuse can blow again immediately.

Are Kenmore microwaves good?
Kenmore microwaves are a good choice for most kitchens because they’re built for dependable everyday cooking and typically offer strong value for the features you get. For the Kenmore 72180412500 microwave/hood combo, long-term satisfaction comes down to correct installation, routine cleaning, and replacing wear items as needed using the 72180412500 owner’s manual.
What “good” usually means for a microwave/hood combo
A microwave/hood combo has to do two jobs: heat food consistently and vent cooking smoke and grease. In real-world use, “good” usually comes down to these factors:
- Even heating and reliable power output
- A door that closes and latches smoothly every time
- Effective venting with clean grease filters
- Simple, durable controls and interior finish
- Easy access to common maintenance items (filters, lights)
What we see most often with Kenmore microwave performance
Kenmore units are generally well-liked for value and features, but like any brand, performance depends on the specific model and how it’s maintained.
| Area | What to expect | What helps most |
|---|---|---|
| Heating | Strong everyday cooking when components are healthy | Avoid running empty; keep interior clean |
| Venting | Good capture when airflow path is correct | Clean/replace grease filter regularly |
| Reliability | Many last for years with normal use | Use proper power supply; don’t slam the door |
| Repairs | Common fixes are straightforward | Use the troubleshooting section in the manual |
Quick checks that protect performance (and reduce repairs)
- Wash or replace the grease filter on schedule (a clogged filter reduces airflow)
- Keep the waveguide cover area clean and free of splatter
- If heating seems weak, stop using it and troubleshoot before it worsens (high-voltage parts can fail)
- If the unit goes dead or won’t start, check the house breaker first, then consider the microwave fuse 3B74133Q
- Confirm the microwave is mounted and vented correctly using the 72180412500 installation guide
Why it matters
A microwave/hood combo like Kenmore 72180412500 is sensitive to airflow, door alignment, and electrical supply. Good installation and basic upkeep usually make the difference between “works great” and “constant annoyance.”

How do I reset a Kenmore microwave?
To reset your Kenmore microwave model 72180412500, unplug it (or switch off the breaker) for about 1 minute, then restore power to clear many control glitches. For model-specific keypad steps and settings behavior, follow the reset and control instructions in the 72180412500 owner's manual.
Quick reset options (most common)
- Power reset: Unplug the microwave for 60 seconds, then plug it back in.
- Breaker reset: Turn the kitchen microwave breaker off for 60 seconds, then back on.
- Clock re-entry: After power returns, set the clock if the display prompts you.
- Stop/clear check: Press the Stop/Cancel (or Clear) key once to exit a stuck cycle.
- Door reset: Open and close the door firmly to re-seat the door interlock.
If the microwave still will not run
A “reset” will not fix a safety-interlock or power problem. If the display is dead, the unit trips power, or it starts and stops, check these common causes:
| Symptom | What it usually points to | What we recommend |
|---|---|---|
| No display, no response | Loss of power or blown internal fuse | Verify outlet power; then have the fuse circuit checked (microwaves store high voltage) |
| Runs but does not heat | High-voltage component issue | Use our troubleshooting steps in why is my microwave not heating |
| Starts when door moves, or stops when closing | Door interlock switch issue | Have the door switch circuit inspected; replace with the correct switch if needed |
Parts that commonly relate to “won’t start” after a reset
- Microwave fuse 3B74133Q (if the unit is completely dead)
- Microwave door interlock switch 6600W1K001R (if door movement affects operation)
- Microwave door interlock switch 6600W1K001Q (alternate switch used in some positions)
Why it matters
Resetting clears temporary control-board logic issues, but it does not correct problems that prevent safe operation (especially door interlocks) or failures in the high-voltage heating circuit.
