How much clearance for a countertop microwave?
For the Kenmore countertop microwave model 72166319500, we recommend placing it on a level surface with at least 4 inches of open space on the left, right, top, and rear so airflow can ventilate the unit properly. This matches the installation guidance in the 72166319500 owner's manual.
Recommended clearances (what to follow)
Use these spacing targets around the microwave cabinet (not the door handle):
- Left side: 4 inches minimum
- Right side: 4 inches minimum
- Top: 4 inches minimum
- Rear: 4 inches minimum
- Front: keep the front unobstructed so the door opens fully and air can move freely
Quick reference table
| Location around microwave | Minimum clearance | Purpose |
|---|---|---|
| Left side | 4 in. | Ventilation airflow |
| Right side | 4 in. | Ventilation airflow |
| Top | 4 in. | Heat dissipation |
| Rear | 4 in. | Prevents blocked vents |
Why it matters
Countertop microwaves pull cooling air in and push warm air out through built-in openings. If the sides, top, or back are too close to a wall or cabinet, restricted airflow can cause overheating, nuisance shutoffs, or internal component damage.
Placement tips that prevent common problems
- Set the microwave on a stable, level counter or shelf.
- Do not place items (paper towels, cookbooks, trays) on top that could block airflow.
- Keep the cord positioned so it does not hang over the counter edge.
- Avoid pushing the unit tight against a backsplash; maintain the rear gap.
- Do not cover or block any openings during use.

Installation clearance (why your “size” may need extra space)
Even if the microwave fits the countertop footprint, it still needs airflow clearance.
- Leave at least 4 inches of space on the left, right, top, and rear
- Keep vents unblocked to prevent overheating
- Set the unit on a level surface so the turntable operates smoothly
Why it matters
Microwave “size” can mean exterior dimensions (cabinet fit) or cavity capacity (how much food fits). Using the correct measurements helps prevent poor ventilation, nuisance shutdowns, and installation headaches.

What is the height of a countertop microwave?
For a countertop microwave, height is typically about 12 to 15 inches. For the Kenmore 72166319500 specifically, the use and care guide lists overall dimensions of 20 3/4 in (W) x 15 7/8 in (H) x 19 1/4 in (D), so the height is 15 7/8 inches. See the 72166319500 owner's manual for the full specifications.
Typical countertop microwave height ranges
Most countertop microwaves fall into these common size bands:
- Compact: about 10 to 12 inches tall
- Mid-size: about 12 to 14 inches tall
- Large: about 14 to 17 inches tall
- Extra clearance needed: plan for ventilation space above the unit
Model-specific dimensions for Kenmore 72166319500
The manual provides the overall exterior dimensions and the interior cavity dimensions.
| Measurement type | Dimension (inches) |
|---|---|
| Overall height | 15 7/8 |
| Overall width | 20 3/4 |
| Overall depth | 19 1/4 |
| Cavity height (interior) | 10 9/32 |
Installation clearance (important for real-world height)
Even though the microwave body is 15 7/8 inches tall, you also need space around it for airflow. The manual calls for at least:
- 4 inches on the left
- 4 inches on the right
- 4 inches on the top
- 4 inches at the rear
Why it matters
Microwave height affects whether it fits under cabinets, on a shelf, or in a microwave cart. Planning for both the cabinet opening and the ventilation clearance helps prevent overheating and nuisance shutdowns.
