How many cubic feet is a Kenmore Model 72180012401 microwave?
The Kenmore microwave/hood combo model 72180012401 has a 1.7 cubic foot oven capacity. This is the interior cooking space, which helps you judge whether common items like dinner plates, casserole dishes, and microwave-safe bowls will fit comfortably.
How to confirm capacity and what it means
Capacity is measured in cubic feet and refers to the usable space inside the microwave cavity (not the exterior size). In the 72180012401 owner’s manual, capacity is listed with other key specs and operating details.
Quick ways we use capacity in real life:
- Fits most standard 10 to 12 inch dinner plates on the turntable
- Handles medium casserole dishes and covered bowls
- Helps estimate how evenly larger items will heat (bigger loads often need stirring or rotation)
- Guides replacement decisions when upgrading or matching an existing cutout
Capacity vs. exterior size (common confusion)
A 1.7 cu. ft. over-the-range microwave like this Kenmore model can still vary in outside width, height, and depth depending on the cabinet and venting design.
| Spec type | What it describes | Why you care |
|---|---|---|
| Oven capacity (cu. ft.) | Interior cooking volume | Fit of dishes and food containers |
| Exterior dimensions | Outside cabinet size | Fit over the range and under cabinets |
| Turntable diameter | Glass tray size | Plate size and rotation clearance |
Why it matters
Choosing the right capacity helps prevent day-to-day frustrations, like plates rubbing the walls, tall containers hitting the top, or oversized dishes blocking turntable rotation. It also helps when ordering parts that relate to the cooking cavity, such as the Kenmore elite microwave glass turntable tray 3390W1A027A.

Can a Kenmore microwave be repaired?
Yes. A Kenmore microwave, including model 72180012401, is repairable when the problem is in common service parts such as the door interlock system, lights, venting pieces, or a blown fuse. For any high-voltage heating problem, we recommend professional service because internal components can store dangerous electrical energy.
What we repair most often on model 72180012401
- No power or dead display (often a blown fuse or door switch issue)
- Runs but does not heat (high-voltage circuit diagnosis)
- Turntable not rotating (motor, coupler, or tray fit issues)
- Cooktop light not working (bulb or lens)
- Venting problems (damper door stuck or noisy)
DIY-safe vs. technician-level repairs
Microwaves contain high-voltage components; we treat anything beyond basic access panels as technician work.
| Repair type | Typical examples | DIY-friendly? |
|---|---|---|
| Basic electrical and access parts | Fuse, light bulb, grease filter | Yes (with power disconnected) |
| Door safety system | Interlock switch alignment or replacement | Sometimes |
| High-voltage heating circuit | Capacitor, transformer, magnetron-related diagnosis | No |

How do I reset a Kenmore microwave?
For the Kenmore 72180012401 microwave/hood combo, the most reliable “reset” is a power reset: unplug the microwave (or switch off the breaker) for about 1 minute, then restore power and reset the clock. This clears many control glitches.
Quick reset options (start here)
- Power reset: Unplug for 60 seconds, then plug back in.
- Breaker reset: Turn the microwave circuit breaker OFF, wait 60 seconds, then turn it ON.
- Control panel check: If the display is locked, turn off the control lock (often a 3-second press on a key such as Stop/Clear or a lock-labeled pad).
- Clock reset: After power returns, set the clock per the 72180012401 owner’s manual.
If it still will not run after resetting
A reset helps when the control is confused; it will not fix a failed door switch, blown fuse, or other electrical problem.
What to check (safe, no disassembly)
- Confirm the outlet has power (test with a small lamp).
- Make sure the door closes firmly and latches fully.
- Try a different cook cycle (for example, Time Cook) after setting the clock.
- If the unit is completely dead (no display), stop using it and plan a repair.
Common parts involved when a “reset” does not help
| Symptom | Likely area | Example part for this model |
|---|---|---|
| No display, totally dead | Line fuse or power feed | Microwave fuse 3B74133Q |
| Runs but does not heat | High-voltage system | Microwave high-voltage capacitor 0CZZW1H004B |
| Starts then stops when door moves | Door interlock circuit | Microwave door interlock switch 6600W1K001Q |
Why it matters
Microwaves contain high-voltage components that can store dangerous energy even when unplugged. A simple power reset is safe; internal testing and part replacement should be done carefully and correctly.

Where is the fuse on a Kenmore microwave model 72180012401?
On the Kenmore 72180012401 microwave/hood combo, the main microwave fuse is typically located behind the top front grille and the control panel area, mounted in a small fuse holder on the noise filter or wiring harness. Use the 72180012401 owner's manual to confirm access steps and safety notes before servicing.
What to check before you open the cabinet
A microwave that looks “dead” is often a power or door-latch issue, not a blown internal fuse.
- Make sure the cord is fully seated in a grounded 3-prong outlet.
- Check the home breaker or household fuse first.
- Confirm the door closes firmly and latches.
- Press STOP/Clear to cancel timer-only operation.
- Try a different outlet (same circuit rating) to rule out a weak receptacle.
Safe, practical access overview (what we recommend)
Microwaves contain high-voltage components that can store a dangerous charge even when unplugged. For fuse access on an over-the-range unit like model 72180012401, we recommend this approach:
- Unplug the microwave (or switch off the circuit at the breaker).
- Remove the top grille (usually screws along the top edge).
- Remove the control panel mounting screw and tilt the panel forward.
- Locate the fuse holder and inspect the fuse.
- Replace only with the exact rated fuse for this model, such as the microwave fuse 3B74133Q.
Quick symptom-to-likely-cause guide
| Symptom | Most common cause | What to do next |
|---|---|---|
| No display, no fan, no light | House power issue or blown fuse | Check breaker/outlet, then inspect fuse |
| Runs but does not heat | High-voltage component issue | Use why is my microwave not heating troubleshooting |
| Blows fuse when door closes/starts | Door switch or short | Inspect door switches and wiring; service recommended |
Why it matters
The fuse is a safety device; it opens to protect the microwave from overloads and shorts. Replacing the fuse without addressing the underlying cause (door interlock switch, wiring damage, or a failing high-voltage part) can lead to repeated failures.
