How many cubic feet is a Kenmore Model 72166462500 microwave?
The Kenmore microwave model 72166462500 has an oven cavity capacity of 2.0 cubic feet (IEC 60705 rating standard), as listed in the specifications section of the 72166462500 owner's manual.
Where to confirm the capacity
We list capacity in the specifications area because it is the most consistent way to compare countertop microwaves.
- Look for “Capacity of oven cavity” in the specs table
- Use the model number 72166462500 to avoid mixing up similar Kenmore models
- Capacity is measured as interior cavity volume, not exterior size
- Exterior dimensions can be larger due to the cabinet, door, and ventilation space
Capacity vs. dimensions (quick reference)
| Spec type | What it describes | Why it matters |
|---|---|---|
| Capacity (cu. ft.) | Interior cooking space | Helps you judge dish size fit and cooking volume |
| Overall dimensions (W x H x D) | Outside size of the microwave | Helps you confirm countertop clearance |
| Oven cavity dimensions (W x H x D) | Interior measurements | Helps you confirm specific dish clearance |
Why it matters
A 2.0 cu. ft. countertop microwave typically fits larger plates and casserole dishes more comfortably than smaller-capacity units, and it is a better match for higher-volume reheating and cooking.

How big is a Kenmore microwave model 72166462500 in inches?
The Kenmore microwave model 72166462500 measures 23 7/8 inches wide x 13 9/16 inches high x 19 13/16 inches deep (overall exterior dimensions). These measurements come from the specifications section in the 72166462500 owner's manual.
Dimensions at a glance
- Overall (exterior) dimensions (W x H x D): 23 7/8 in x 13 9/16 in x 19 13/16 in
- Cavity (interior) dimensions (W x H x D): 16 1/16 in x 11 1/4 in x 18 1/2 in
- Ventilation clearance needed: plan for at least 4 inches on the left, right, top, and rear
Exterior vs. interior size (why the numbers differ)
Microwave listings sometimes mix up exterior size with cavity size. Use this quick comparison to make sure you are measuring the right thing.
| Measurement type | What it tells you | Use it for |
|---|---|---|
| Overall dimensions | Outside cabinet size | Counter space, shelf fit, trim-kit opening checks |
| Cavity dimensions | Usable cooking space inside | Dish size, casserole fit, turntable clearance |
How we recommend measuring your microwave
If you are confirming fit for a countertop, cabinet shelf, or built-in trim kit, we recommend measuring the unit you have.
- Measure width across the widest outside points (usually the side panels)
- Measure height from the counter to the top of the cabinet (not the door)
- Measure depth from the back to the front edge (exclude the cord; include the door if it protrudes)
- Leave space for airflow; blocked vents can cause overheating
Why it matters
Correct dimensions help prevent poor ventilation, door clearance issues, and installation problems. For the Kenmore 72166462500, the manual also calls out clearance space, which is just as important as the cabinet measurements.

Why is my Kenmore microwave not spinning?
If your Kenmore microwave model 72166462500 isn’t spinning, the most common causes are an incorrectly seated turntable/roller rest, debris blocking the roller path, or a failed turntable motor. Start by reseating the roller rest and glass tray exactly as shown in the 72166462500 owner's manual.
Quick checks we recommend first
- Unplug the microwave for safety.
- Remove the glass tray; wash and dry it.
- Remove the turntable support; clean the oven floor where it rides.
- Reinstall the support in the floor circle, then set the glass tray on top (never upside down).
- Confirm the tray sits flat and can rotate freely by hand.
- Make sure no oversized dish is rubbing the tray or walls.
What usually fails when it still won’t rotate
If the tray and support are installed correctly and it still won’t spin during a cook cycle, these are the most likely issues:
| Symptom | Most likely cause | What to do next |
|---|---|---|
| Tray is hard to turn by hand | Food spill, warped tray, mis-seated support | Clean and reseat; replace damaged tray/support if needed |
| Tray turns by hand but not under power | Turntable motor not running | Test motor circuit; replace motor if failed |
| Intermittent rotation | Binding support, worn coupler, weak motor | Inspect for wobble, scraping, or flat spots |
A failed turntable motor is a common repair on countertop microwaves; on this model, the motor is listed as motor 6549W1S011B.
Why it matters
The turntable helps distribute microwave energy more evenly. When it stops rotating, you often get hot spots, cold spots, longer cook times, and more boil-overs.

Why is my Kenmore microwave display not working?
If the display on your Kenmore microwave model 72166462500 is blank or unresponsive, the most common causes are a power issue (outlet, cord, fuse), a door-interlock problem, or a failed control/display circuit. Start with a simple power reset, then check the basic “won’t start” items listed in the 72166462500 owner's manual.
Quick checks we recommend first
- Unplug the microwave for 5 minutes, then plug it back in to reset the control.
- Confirm the outlet has power (try a lamp or small appliance).
- Make sure the door closes firmly and latches fully; a misaligned latch can keep the unit “dead.”
- If the unit is totally dead, check the internal fuse; a blown fuse often points to an underlying issue.
- If the display is dim or flickers, suspect a control board/display problem rather than the fuse.
What the manual troubleshooting points to
The manual’s “Before calling for service” section focuses on basic start-up conditions: power cord plugged in, door closed, and cooking time set. If the display is out, those same basics still apply because the control needs stable power and a closed door circuit to wake up. Use the 72166462500 owner's manual troubleshooting section as your checklist.
Parts that commonly relate to a dead display
| Symptom | Most likely area | Example part for this model |
|---|---|---|
| Completely blank, no response | Power path or protection | Microwave fuse 3B74133Q |
| Works sometimes, door feels “off” | Door interlock/latch system | Microwave door interlock switch (varies by position) |
| Runs but does not heat (display may still work) | High-voltage system | Magnetron, diode, capacitor |
Why it matters
A blank display is usually a sign the control is not getting proper power or is being held off by a safety interlock. Replacing only the fuse without addressing the root cause can lead to repeat failures.

Is there a reset on a Kenmore microwave?
Yes. On Kenmore model 72166462500, the practical “reset” is a power reset: unplug the microwave (or switch off the breaker) for about 1 minute, then restore power and re-set the clock. This clears many control glitches without changing normal cooking features.
Quick reset steps (safe, no disassembly)
- Press STOP/CLEAR once to cancel a cooking cycle.
- Unplug the microwave (or turn the circuit breaker OFF).
- Wait 60 seconds.
- Restore power.
- Set the clock and test with a short heat cycle (for example, 1 cup of water for 60 seconds).
What a reset can and cannot fix
A reset helps when the display is frozen, buttons act odd, or the unit will not start a cycle. It will not fix a no-heat condition caused by a failed high-voltage part.
| Symptom | Reset worth trying? | What to check next |
|---|---|---|
| Display locked up or random beeps | Yes | Power reset, then clock setting in the 72166462500 owner's manual |
| Runs but does not heat | Sometimes | Heating circuit parts (magnetron, diode, capacitor) and door switches; use why is my microwave not heating |
| Completely dead (no display) | Sometimes | House outlet, then internal fuse such as microwave fuse 3B74133Q |
If the microwave still will not run after resetting
- Confirm the outlet has power (try a lamp or phone charger).
- Make sure the door closes firmly; a misaligned latch can prevent starting.
- If it is dead or blows power when starting, have the fuse and door interlock circuit checked.
- If it runs but does not heat, the magnetron circuit is the common area to diagnose.
Why it matters
Microwaves can store high voltage even when unplugged. A simple power reset is the safest first step; deeper electrical testing and high-voltage repairs should be handled by a qualified technician.

Is Kenmore a good microwave?
Kenmore microwaves are a good choice for most homes because they typically deliver strong cooking performance for the price, and the Kenmore 72166462500 is a full-size 2.0 cu. ft. countertop model rated at 1,200 watts output. Long-term satisfaction comes down to using it correctly, keeping airflow clear, and repairing common wear items when needed (see the 72166462500 owner's manual).
What “good” means for the Kenmore 72166462500
From the model’s specs, this microwave is built for everyday family use: standard 120 VAC power, high output, and a larger cavity.
- Microwave output: 1,200 W
- Capacity: 2.0 cu. ft.
- Power supply: 120 VAC, 60 Hz
- Rated power consumption: 1,600 W
- Ventilation clearance: at least 4 inches on left, right, top, and rear
| What to evaluate | What to look for | Why it matters |
|---|---|---|
| Heating performance | Food heats evenly, no long cook times | Indicates healthy high-voltage system (magnetron, diode, capacitor) |
| Door operation | Door closes firmly, no slamming | Protects interlock switches and latch parts |
| Noise and airflow | Fan runs, air vents are not blocked | Prevents overheating and shutdowns |
| Turntable function | Tray rotates smoothly | Improves even cooking and reduces hot spots |
Common “good microwave” ownership tips
These habits make a bigger difference than brand name alone.
- Keep vents clear and maintain the recommended 4-inch clearance for airflow.
- Avoid running the microwave empty; it stresses the magnetron.
- Use only microwave-safe containers; avoid sealed jars and whole eggs.
- Keep the waveguide area clean; replace a damaged cover to prevent arcing.
- If it stops heating, focus troubleshooting on the high-voltage components.
When a Kenmore microwave seems “not good”
Most complaints trace back to a few repairable issues. If the unit runs but does not heat, the high-voltage circuit is the first place we look, including the microwave magnetron 6324W1A001L. For symptom-based guidance, use why is my microwave not heating.
Why it matters
A microwave can feel “weak” even when it is working normally if airflow is restricted, the turntable is not rotating, or the cooking method does not match the power level. Following the manual’s setup and safety guidance helps protect performance and extend service life.

Where is the fuse on a Kenmore microwave model 72166462500?
On the Kenmore 72166462500 countertop microwave, the fuse is mounted inside the cabinet near where the power cord enters the unit (typically on or near the noise filter/control area). Accessing it requires removing the outer cover; use the 72166462500 owner's manual for safety and service guidance.
Before you check the fuse
Microwaves store high voltage even when unplugged, so we treat fuse access as a cabinet-off repair.
- Unplug the microwave before doing anything
- If the unit is built in with a trim kit, remove it from the opening first
- Use a flashlight and take a photo of wire locations before disconnecting anything
- Replace a blown fuse only after finding the cause (door switch, shorted component, wiring)
- If you see heat damage or melted wiring, stop and have the unit serviced
Common symptoms of a blown microwave fuse
A blown fuse often shows up as a total loss of power.
| Symptom | What you usually see | What it often points to |
|---|---|---|
| Dead display, no interior light | No response at all | Blown fuse or no power supply |
| Fuse blows when door opens/closes | Intermittent or immediate failure | Door interlock switch issue |
| Fuse blows when pressing Start | Runs briefly then dies | High-voltage component short |
Parts that commonly relate to fuse problems on this model
If the fuse is blown repeatedly, these are frequent culprits on countertop microwaves like the Kenmore 72166462500:
- Microwave fuse 3B74133Q (the line fuse itself)
- Door interlock switches (misaligned or shorted)
- Microwave door interlock switch 6600W1K001R (one of the interlock switches used on this model)
- High-voltage components such as the microwave diode 6851W1A002E or capacitor 0CZZW1H004B
Why it matters
The fuse is a safety device that protects the microwave from overheating and electrical shorts. Replacing the fuse without correcting the underlying problem can cause the new fuse to blow again and can damage wiring or other components.
