Quick reference table

Measurement	Size
Width	29 15/16 in.
Height	16 7/16 in.
Depth	15 11/16 in.
Cavity capacity	1.6 cu. ft.

Why it matters

Getting the exact width, height, and depth for 72180039700 helps you confirm cabinet fit, required clearance above the cooktop, and whether your venting plan (roof venting, wall venting, or recirculating) will work before you start drilling.

Helpful tip before you measure

• Measure the cabinet opening width (commonly 30 in. minimum for over-the-range installs)
• Confirm the distance from cooktop to cabinet bottom meets the minimum clearance
• Plan the power cord hole location in the upper cabinet
• Decide on venting method before cutting any duct openings

For the Kenmore 72180039700 microwave/hood combo, the exact exhaust fan CFM rating is not identified in the model-specific information we have for this unit. In general, most microwave hood combinations are designed in the 200 to 500 CFM range, depending on the fan speed and venting setup.

What to check on your Kenmore 72180039700

The most reliable places to confirm CFM are the product rating label and the ventilation section of the documentation.

• Check the model and serial label (often on the oven front area or inside the door frame)
• Review the ventilation and exhaust fan operation details in the 72180039700 use & care manual
• If you are changing venting (room venting vs wall or roof venting), follow the 72180039700 installation instructions
• Confirm your duct type and length; long duct runs and multiple elbows reduce real airflow
• Make sure filters are clean; clogged filters can noticeably cut airflow

Typical CFM ranges (helpful for planning)

Venting product type	Typical CFM range	Common use case
Microwave/hood combo	200 to 500	Light to moderate cooking
Standard under-cabinet range hood	200 to 600	Moderate to heavier cooking
Commercial-style hood	Up to ~1200	High-heat, frequent cooking

Why it matters

CFM affects how well your microwave hood clears smoke, steam, and odors. If your cooking style includes frequent frying, high-heat searing, or wok cooking, choosing a higher-CFM ventilation solution (and proper ducting) can make a noticeable difference.
