Kenmore 72180419500 microwave Parts

The Kenmore microwave/hood combo model 72180419500 measures 29-15/16 inches wide, 16-7/16 inches high, and 15-3/8 inches deep (overall cabinet dimensions). These are the standard outside dimensions used for over-the-range fit and installation.

Dimensions for Kenmore 72180419500

• Width: 29-15/16 in.
• Height: 16-7/16 in.
• Depth: 15-3/8 in.
• Weight (for handling/installation): 54 lb

For the most accurate fit details (including mounting clearances and cabinet requirements), we recommend checking the installation guide.

Why these measurements matter

These are the dimensions you use to confirm:

• The microwave will fit between cabinets (common target is a 30-inch opening).
• The unit will clear the backsplash and upper cabinet face frame.
• The mounting plate and venting path will line up (rear wall or top cabinet).
• You have enough depth so the door opens freely.

Quick fit check before you buy or install

Measure your space and compare it to the microwave size:

• Measure the opening width between cabinets.
• Measure upper cabinet depth and the distance to the back wall.
• Confirm the bottom clearance above the cooktop.
• Verify where the power supply is located (typically in the cabinet above).

Typical over-the-range microwave sizing (comparison)

Item	Typical range	Kenmore 72180419500
Width	~29-7/8 to 30 in.	29-15/16 in.
Height	~16 to 17 in.	16-7/16 in.
Depth	~15 to 17 in.	15-3/8 in.

Related installation note

Because this is a heavy microwave/hood combo, we follow the two-person lift guidance and mounting steps shown in the installation guide to prevent damage to the mounting plate, cabinet, or vent damper parts.

The Kenmore microwave/hood combo model 72180419500 is typically a 1.7 cu. ft. over-the-range microwave. For the exact capacity and the full spec list for your unit, we recommend confirming it in the 72180419500 owner's manual.

How to confirm the capacity on your exact unit

Use these quick checks to make sure you are matching the right specs to your microwave:

• Match the full model number on the label (on the oven front area per the installation instructions).
• Check the “Getting to know your microwave oven” or specifications section in the manual.
• If your microwave has a trim kit or custom cabinet surround, ignore the opening size and use the model specs.
• If you are comparing to a replacement, compare capacity and exterior width (most OTR units are about 30 inches wide).

Typical specs you will see for this model class

Many Kenmore over-the-range microwaves in the 721.804xx family are commonly listed around these values:

Spec	Typical value for this model class
Oven capacity	1.7 cu. ft.
Output power	About 1000 watts
Exterior width	About 30 inches

Why it matters

Capacity (cubic feet) affects what fits inside (plates, casserole dishes) and also helps you match the right replacement parts and accessories, such as a turntable tray and filters.

Parts that often relate to fit and day-to-day use

If you are checking capacity because you need common maintenance items, these are frequently replaced on microwave/hood combos:

• Grease filter (helps protect the vent fan and cabinet area)
• Cooktop light bulb (lights the range surface)
• Turntable components (tray, support, motor)
• Door interlock switches (help the unit run only when the door is closed)

For example, this model has a microwave glass turntable tray MJS65336701 available.

Kenmore microwaves (including model 72180419500) are made by different OEM manufacturers depending on the specific model and production run; Kenmore is a brand name, not a single factory. To identify the maker for your exact unit, we use the model and serial label locations shown in the installation guide.

How to identify the manufacturer for model 72180419500

The most reliable way is to check the product identification label and compare the model format.

• Locate the model number label on the oven front (noted in the installation instructions).
• Record the complete model number and serial number.
• Check the model and serial label/plate at the upper side of the cavity front (noted in the owner documentation).
• Use those numbers when selecting parts so you match the correct OEM design.

Common OEMs behind Kenmore microwaves

Kenmore has sourced microwave/hood combos from multiple manufacturers over the years. Depending on the model series, you may see designs associated with:

• LG (often seen in many 721-prefix microwave models)
• Whirlpool
• Panasonic
• Other OEM suppliers used for specific runs

Why the OEM matters for parts and repairs

Different OEM designs can use different door switch stacks, venting hardware, and high-voltage components even when the appliance is branded Kenmore.

What you are doing	Why OEM identification helps	Example part on this model page
Replacing a no-heat component	Ensures correct electrical and mounting match	Microwave magnetron 2B71165R
Fixing door-closed errors	Matches the correct interlock style	Microwave door interlock switch 6600W1K001D
Restoring ventilation performance	Confirms damper style and fit	Microwave vent damper door 4900W1A001B

Quick tip if your microwave runs but does not heat

If the fan and turntable run but food stays cold, the issue is often in the high-voltage heating circuit (magnetron, diode, capacitor). We use the troubleshooting guidance in the owner's manual to narrow symptoms before replacing parts.

Kenmore microwaves are a solid, dependable choice for everyday heating and venting, and the Kenmore 72180419500 microwave/hood combo is built for typical household use with standard care and maintenance. Like any microwave, long-term reliability depends most on proper installation, clean airflow, and not running it empty.

What “good” means for a microwave/hood combo

A microwave/hood combo has two jobs: cooking performance and range-hood ventilation. In real use, “good” usually comes down to these factors:

• Heats evenly for common tasks (reheating, beverages, defrosting)
• Door closes and latches smoothly every time
• Vent fan moves air well and the grease filter is kept clean
• Interior stays clean to prevent odors, arcing, and staining
• Lights and turntable operate consistently

For model-specific operating and care guidance, use the owner's manual.

Reliability: what typically fails first

Across over-the-range microwaves, the most common trouble areas are door safety switches, lighting, turntable drive parts, and (less often) high-voltage heating components.

Symptom	Common cause	Example part for 72180419500
Runs but does not heat	High-voltage component issue	Microwave magnetron 2B71165R
Dead or intermittent power	Fuse/door switch circuit issue	Microwave door interlock switch 6600W1K001D
Turntable not rotating	Motor or support problem	Microwave turntable motor 6549W1S011M
Poor venting or greasy buildup	Clogged filter	Goldstar microwave grease filter 5230W1A012B

Why it matters

A microwave that is installed correctly and kept clean runs cooler, vents better, and puts less stress on key parts like thermostats, door switches, and the magnetron. That directly improves day-to-day performance and helps prevent nuisance shutdowns.

Tips that keep performance “good” over time

• Clean interior surfaces regularly with mild soap and water; avoid abrasives.
• Keep the door and frame contact surfaces clean so the door seals properly.
• Clean or replace the grease filter on a routine schedule.
• Use microwave-safe containers and avoid metal to prevent arcing.
• If heating performance drops, troubleshoot before replacing major parts.
