Owner’s manual
Where can I find my Kenmore microwave model number?
You can find the model number for your Kenmore countertop microwave on the rating label, which is typically located around the door area (door frame or along the edge of the control panel) or on the back of the cabinet. Use the exact model number to match parts and the correct owner's manual.
- Open the door and look on the oven frame (the front face around the opening)
- Check the door edge area near the latch side
- Look along the side of the control panel trim
- Inspect the back panel of the microwave cabinet
- If the unit is in a tight space, slide it forward to view the rear label safely
For this Kenmore model, the full model number is 72179159010 (you may also see a shortened series like 721.7915 in documentation). Use the full number when ordering parts.
| Where you see it | What it’s used for | Example for this unit |
|---|---|---|
| Rating label on the microwave | Parts lookup and compatibility | 72179159010 |
| Manual cover/model list | Identifying the model series | 721.7915 |
The model number is how we match the correct replacement parts and diagrams for your exact build. Even small model-number differences can change which door interlock switch, turntable tray, or internal electrical parts fit.

Can you put a countertop microwave in a cabinet with a trim kit?
Yes, you can place the Kenmore 72179159010 countertop microwave in a cabinet with a trim kit, as long as the installation maintains the required airflow and does not block any openings. This model needs at least 4 inches of clearance on the left, right, top, and rear for proper ventilation.
Our key rule is simple: the microwave must breathe. The manual for Kenmore 72179159010 calls for clear space around the unit and warns that blocking inlet or outlet openings can damage the microwave.
- Keep at least 4 inches of space at the left, right, top, and rear
- Do not cover or block any openings
- Do not store items on top of the microwave while it is operating
- Use a level, stable surface inside the cabinet
- Keep the power cord away from heat and sharp edges
For the exact placement guidance and safety notes, follow the owner's manual.
A trim kit can make a built-in look, but it only works if it is designed to vent correctly for a countertop unit.
| What to verify | What “good” looks like | What to avoid |
|---|---|---|
| Airflow path | Vents remain open and unobstructed | Vents covered by wood, trim, or insulation |
| Cabinet space | Clearance maintained on all sides | Tight enclosure with no air gap |
| Heat management | Warm air can exit the cabinet | Heat trapped around the chassis |
| Door operation | Door opens freely, no binding | Door rubbing trim or cabinet face |
Microwaves generate heat in normal operation. When airflow is restricted, internal components can overheat, which can shorten the life of parts like the magnetron, high-voltage capacitor, and cooling fan.
If your microwave later runs but does not heat, we recommend starting with our troubleshooting steps in why is my microwave not heating.

What is the wattage of a Kenmore microwave?
For the Kenmore countertop microwave model 72179159010, the cooking (microwave output) wattage is 1,200 watts. This is the heating power used to cook food; it is different from the electrical power the microwave draws from the outlet.
Here are the key power specs we use for troubleshooting and comparing microwaves (from the owner's manual):
| Spec | What it means | Value |
|---|---|---|
| Microwave output | Cooking power delivered to food | 1,200W |
| Rated power consumption | Power the unit draws while running | 1,750W |
| Rated current | Approximate amperage draw | 14.5A |
| Power supply | Household electrical requirement | 120V AC, 60 Hz |
Microwave output wattage is the number that affects cook times and performance. Two microwaves can both plug into a standard 120V outlet, but the one with higher output watts typically heats faster and more evenly.
If your 72179159010 seems to take longer than expected, we recommend these checks:
- Confirm you are using a microwave-safe container (some dishes absorb energy and slow heating).
- Make sure the door closes fully and latches securely.
- Avoid running the microwave on an overloaded circuit (shared outlets can reduce performance).
- If your outlet voltage is low (below about 110V), cooking times can increase.
- If the unit runs but does not heat, focus on the high-voltage heating system.
If the display works and the turntable runs but food stays cold, the problem is usually a failed heating component, not “low wattage.” Common suspects include the microwave magnetron 6324W1A001L or other high-voltage parts.

How big is the Kenmore 72179159010 microwave?
The Kenmore 72179159010 countertop microwave is 21 7/8 inches wide x 12 1/2 inches high x 17 1/32 inches deep overall. The oven cavity is 15 21/32 inches wide x 10 7/16 inches high x 15 27/32 inches deep, and capacity is 1.5 cu. ft. (see the 72179159010 owner's manual).
| Spec | Measurement |
|---|---|
| Overall dimensions (W x H x D) | 21 7/8" x 12 1/2" x 17 1/32" |
| Oven cavity dimensions (W x H x D) | 15 21/32" x 10 7/16" x 15 27/32" |
| Oven capacity | 1.5 cu. ft. |
- Leave at least 4 inches of open space on the left, right, top, and rear for ventilation.
- Place the microwave on a level, stable surface.
- Keep air inlet and outlet openings clear.
- Install the turntable correctly; a missing or mis-seated tray can cause noise and poor cooking.
Using the correct overall dimensions prevents fit issues in a cabinet cutout or on a shelf. Following the ventilation clearance helps prevent overheating that can shorten the life of components such as the cooling fan motor and thermostat.
