What “size” can mean (and what we can confirm)
On over-the-range microwaves like this Kenmore model, “size” is commonly used in two ways:
- Exterior dimensions (what fits between cabinets and above the range): confirmed above.
- Cutout/cabinet opening requirements (space needed for installation): partially specified in the install guide.
- Interior capacity (cu. ft.): not identified in the model-specific document text we have here.
Quick fit checklist before you buy or install
- Plan for a 30-inch minimum cabinet opening width.
- Keep 30 inches minimum from the bottom of the upper cabinet to the cooking surface/countertop.
- Use a dedicated 120V, 60Hz, 20A electrical supply as specified.
- Use two people for lifting and mounting; this unit is heavy.

Is Kenmore a good microwave?
Kenmore microwaves are a solid, dependable choice for most kitchens, and the Kenmore 72180413500 microwave/hood combo is built with the core features people expect (turntable cooking, multiple power levels, exhaust fan, cooktop light). “Good” ultimately comes down to fit, features, and how well it’s installed and maintained.
What “good” means for this Kenmore 72180413500
We can’t rate a specific unit’s performance from the model number alone, but we can point to practical indicators you can use to judge whether this model is a good match for your needs. For operating features and care basics, use the 72180413500 use & care manual.
- Over-the-range convenience: combines microwave cooking with a vent hood.
- Everyday cooking features: timed cooking, multiple power levels, defrost options, and sensor-style cooking functions.
- Vent hood functions: exhaust fan speeds and cooktop lighting.
- Serviceability: common wear items (filters, bulbs, fuses) are replaceable.
Quick fit check (often the deciding factor)
If you’re choosing this model for a space, installation fit matters as much as brand. The installation instructions list the oven’s overall dimensions and electrical requirements; see the 72180413500 installation instructions.
| What to verify | Why it matters |
|---|---|
| Cabinet opening and clearances | Prevents install problems and heat or airflow issues |
| Dedicated electrical supply | Helps avoid nuisance power issues |
| Venting method (room, wall, roof) | Impacts smoke/odor removal and noise |
Maintenance that keeps performance “good”
A microwave/hood combo usually performs well for years when airflow and basic upkeep are handled.
- Clean the grease filters regularly.
- Replace the charcoal filter on recirculating setups when odors linger.
- Keep the door seals and sealing surfaces clean.
- Use microwave-safe cookware and avoid metal or foil contact.
Why it matters
Most “bad microwave” complaints are really installation, venting, or maintenance issues (poor airflow, grease buildup, wrong cookware), not the badge on the front. Starting with the correct setup and routine filter care makes a noticeable difference.

How do I reset my Kenmore microwave?
To reset your Kenmore microwave model 72180413500, unplug it (or turn off the breaker) for about 1 minute, then restore power and set the clock. If the control panel is locked, press and hold STOP/Clear until the lock clears (about 4 seconds); see the 72180413500 use & care manual.
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.
- Clear a bad setting: Press STOP/Clear once to cancel a cooking program.
- Exit Child Lock: Press and hold STOP/Clear until LOCKED disappears (about 4 seconds).
- After a power loss: Set the clock; the display may prompt you to set time of day.
What to expect after a reset
| What you see | What it usually means | What to do |
|---|---|---|
| “PLEASE SET TIME OF DAY” | Power was interrupted | Set the clock |
| “LOCKED” | Child Lock is on | Hold STOP/Clear ~4 seconds |
| No response to keypad | Control issue or no power | Verify outlet/breaker, then power reset |
If it still will not reset
If your 72180413500 display stays blank, keeps resetting, or goes dead when you press START, focus on power supply and protection components.
- Confirm the outlet has power (try a small lamp).
- Avoid extension cords; use a properly grounded outlet.
- If the unit is completely dead and power is good, a blown internal fuse is a common cause; use how to replace a microwave fuse for safe, step-by-step guidance.
- If you determine the internal fuse is blown and you are replacing it, match the correct replacement for this model, such as the microwave fuse 3B74133Q.
Why it matters
A proper reset clears a stuck keypad command, exits Child Lock, and restores normal operation after a power interruption. If the microwave repeatedly loses power, resetting alone will not fix the underlying electrical or component problem.
