Is there a reset on a Kenmore microwave?
Yes. On Kenmore model 72180609500, the practical “reset” is a power reset: unplug the microwave (or switch the breaker off) for about 1 minute, then restore power. For most control issues, pressing STOP/Clear also cancels a stuck program and returns the oven to standby.
Quick reset options (from easiest to strongest)
- STOP/Clear: cancels an active cooking program or a timer and clears many keypad mistakes.
- Power reset: unplug for about 60 seconds (or turn the circuit breaker off, then back on).
- Clock re-entry: after a power reset, set the clock again if the display prompts you.
- Door reset: open and firmly close the door to ensure it latches; the oven will not run if the door is not fully latched.
What a reset fixes (and what it does not)
A reset helps when the control is confused, a timer is running, or a prior operation is still programmed. It does not fix a no-power condition caused by a blown house fuse, tripped breaker, or an internal failure.
| Symptom | Best first step | Next step if it continues |
|---|---|---|
| Microwave will not start but display works | Press STOP/Clear | Power reset for 1 minute |
| Display is blank | Check outlet and breaker | Check internal fuse (service-level) |
| Runs but does not heat | Not a reset issue | Heating circuit diagnosis (service-level) |
Why it matters
Microwave/vent hood combos like the Kenmore 72180609500 use door interlocks and programmed control logic; clearing a stuck program with STOP/Clear or rebooting the control with a power reset often restores normal operation without replacing parts.
If the microwave still will not run
- Confirm the cord is plugged into a grounded 3-prong outlet.
- Check the household breaker or fuse.
- Make sure the door is fully closed and latched.
- If you suspect an internal fuse issue, use our how to tell if a fuse is blown guide for safe, basic checks.
- For wiring or component testing, follow the safety and electrical guidance in the owner's manual.

How many cubic feet is a Kenmore Model 72180609500 microwave?
The Kenmore 72180609500 microwave/vent hood combination has a typical capacity of about 1.7 cubic feet. For the exact capacity listed for your specific unit and configuration, we recommend confirming it in the 72180609500 owner's manual.
How to confirm the capacity on your model
Capacity is usually shown in the specifications section of the manual or on the model rating label.
- Check the specifications pages in the 72180609500 owner's manual
- Look for the model and serial tag (commonly inside the door opening area)
- Match the full model number exactly: 72180609500
- If your unit was replaced or reworked, verify the tag matches the door and control panel
Why capacity matters
Microwave capacity affects what fits on the turntable, how evenly food heats, and which cookware sizes work best. It also helps when comparing replacement options or checking clearances for an over-the-range installation.
Quick reference: what “1.7 cu. ft.” means in everyday use
| Capacity | Typical fit | Common use cases |
|---|---|---|
| 1.6 to 1.8 cu. ft. | Medium casserole dish, standard dinner plate | Daily reheating, sensor cook programs |
| 1.9 to 2.2 cu. ft. | Larger cookware, bigger plates | Family-size reheating, larger covered dishes |
Related parts that affect usable space and performance
These parts do not change the cubic feet rating, but they can affect how well the microwave operates day to day:
- Turntable drive issues: microwave turntable motor 6549W1S013H
- Heating performance issues: microwave magnetron 6324W1A001L
- No power or intermittent power: us pressed steel microwave fuse 3B74133Q

Can I replace a microwave with a range hood?
Yes; you can replace a Kenmore 72180609500 microwave vent hood combination with a dedicated range hood, as long as the new hood fits the cabinet opening and you have a safe electrical connection and a venting plan (recirculating, wall vent, or roof vent). Use the installation guide to understand how the existing unit is mounted and vented.
What to check before you buy a hood
- Width and cabinet clearance: Match the hood width to your cooktop and the cabinet opening above.
- Venting method: Decide recirculating (charcoal filter) vs ducted (wall or roof).
- Duct location: Confirm whether your current setup vents through the wall, through the roof, or recirculates.
- Power supply: Verify the outlet location and that the circuit is appropriate for the new hood.
- Mounting and wall support: A microwave uses a mounting plate and upper-cabinet fasteners; a hood may mount differently.
Venting options (how they compare)
| Option | Where air goes | Typical requirement | Good fit when |
|---|---|---|---|
| Recirculating | Back into kitchen | Charcoal filter, no duct | No ductwork available |
| Wall vented | Out through rear wall | Rear duct path | Exterior wall behind unit |
| Roof vented | Out through ceiling/roof | Vertical duct path | Duct can run upward |
What changes during the swap
Most over-the-range microwaves (including model 72180609500) are installed using a wall mounting plate and upper-cabinet bolts, and the blower can be configured for different vent directions. Plan for patching or covering old holes and aligning the new hood’s mounting pattern.
Safety and install planning
- Shut off power at the breaker before removal.
- Support the microwave during removal; it is heavy and awkward.
- Avoid pulling or stretching any wiring during disassembly.
- If you are changing from ducted to recirculating, plan on using a charcoal filter setup.
Why it matters
Fit and venting are the two make-or-break details. A hood that does not match your cabinet opening or duct path can lead to poor smoke capture, extra cabinet modifications, and noisy operation.
If you need mounting or venting parts for the existing setup while you plan the change, you can order replacement parts for model 72180609500 from the parts list on this page, or search by model number on Sears PartsDirect.

Where is the fuse on a Kenmore microwave model 72180609500?
On the Kenmore microwave vent hood combination model 72180609500, the main fuse is typically mounted on the internal noise filter or control-area wiring near where the power cord enters the unit, behind the top grille and outer cover. Use the 72180609500 owner's manual for the correct access steps and safety notes before checking it.
What to check before you open the microwave
Microwaves contain high-voltage components that can store a dangerous charge even when unplugged. For fuse-related symptoms, we focus on safe, external checks first.
- Unplug the microwave (or switch off the breaker) for 2 minutes, then restore power
- Confirm the outlet has power (test with a lamp or meter)
- Check for a tripped kitchen GFCI outlet upstream
- If the display is dead and the outlet is good, the internal fuse is a common cause
- If it goes dead when you open or close the door, a door interlock switch issue is also common
Common fuse location and access (typical for this Kenmore style)
Most Kenmore over-the-range units like 72180609500 place the fuse behind the top grille and outer cabinet, close to the incoming power wiring. The fuse is usually in a small clip holder.
Typical access path:
| Step | What you remove | Why it matters |
|---|---|---|
| 1 | Power (unplug or breaker off) | Prevents shock and protects the control board |
| 2 | Top grille | Provides access to the outer cover screws |
| 3 | Outer cover (cabinet) | Exposes the fuse area near the cord entry |
Parts that are often involved when a fuse blows
A blown fuse is sometimes a symptom, not the root cause. If the fuse tests open, these parts are commonly checked next.
- Us pressed steel microwave fuse 3B74133Q (replacement fuse option for this model)
- Door interlock switches (a sticking or shorted switch can pop the fuse)
- Microwave micro-switch 3B73361E (one of the interlock switch options listed for this model)
- Microwave thermostat 6930W1A003J (overheat protection that can interrupt operation)
Why it matters
Replacing a fuse without correcting the underlying problem can lead to repeated fuse failures, no power, or intermittent shutdowns. Using the correct fuse type and verifying door-switch operation helps restore reliable operation.

Why isn't my microwave vent working?
If the vent (exhaust fan) on your Kenmore 72180609500 microwave/hood combo is not moving air, the usual causes are a blocked vent path, a saturated recirculating filter, or a fan control issue. This model also turns the fan on automatically at high speed when the cooktop below gets too hot.
Quick checks (no tools)
- Press the fan button and try each speed setting.
- If you hear the fan but feel little airflow, check for a blocked wall cap or roof cap.
- Look for crushed ducting, loose transitions, or heavy grease buildup.
- If your setup is recirculating, replace the charcoal filter on schedule.
- If the fan will not run at all, reset the breaker and confirm the outlet has power.
Normal behavior that can seem like a failure
The exhaust fan can switch on by itself when heat from the range or cooktop gets too hot. It runs at a high setting to protect the microwave and may stay on up to an hour; the keypad will not let you turn it off during that cooling cycle. See the 72180609500 owner's manual for details.
Installation and venting setup problems
This microwave ships set up for recirculating; the blower must be repositioned for wall venting or roof venting. A mismatched blower orientation or damper that cannot open will cause weak or no venting. Use the 72180609500 installation guide to confirm the correct configuration.
Parts that commonly affect vent performance
| Symptom | Most likely cause | Common fix |
|---|---|---|
| Fan runs, weak airflow | Blocked duct or saturated filter | Clear restriction; replace filter |
| Fan dead on all speeds | Control, wiring, or fan circuit issue | Diagnose wiring and controls |
| Fan turns on by itself | Overheat protection | Let it run until it cools |
Common maintenance part for recirculating setups: lg microwave charcoal filter 5230W1A003A.
Why it matters
Good venting removes smoke and steam and protects the microwave from heat rising off the cooktop. Most airflow complaints come from duct restrictions or a clogged charcoal filter.
