• Confirm vertical clearance for the 16-7/16 inch height plus room to lift and hang the unit.
• Measure depth from the wall to the front edge of the cabinet to account for the 15-3/8 inch depth.
• Verify the mounting plate location and wall structure (studs) before drilling.
• Plan for the power supply location in the cabinet above the microwave.

The most common issues we see with the Kenmore Elite 72180822500 microwave/hood combo are no heat, dead display or no power, turntable not rotating, door not starting the cook cycle, and weak venting or poor lighting. Many of these symptoms trace to a fuse, door interlock switches, or airflow filters.

Common symptoms and likely causes

• Microwave runs but doesn’t heat: high-voltage components (diode, capacitor) or a control issue
• Completely dead (no lights, no display): blown fuse, power cord/connection, or thermostat/thermal cutout
• Starts then stops when you close the door or press Start: door interlock switch problem or misaligned latch
• Turntable not turning: failed turntable motor or tray/coupler binding
• Vent fan weak or smoky kitchen air: clogged grease filter or charcoal filter (recirculating setups)
• Cooktop light out: bulb or socket/housing issue

Quick checks we recommend first

1. Confirm the outlet has power (try a small appliance).
2. Unplug the microwave for 2 minutes, then restore power.
3. Check that the door closes firmly and the latch area is clean.
4. Inspect and clean the hood filters; replace if damaged.
5. If the unit is dead, test the fuse using a meter.

• Use the wiring and component locations in the 72180822500 owner’s manual.
• For safe electrical testing basics, follow how to use a multimeter to test electrical parts video.

Parts that commonly fix these problems

Symptom	Common part to check/replace	Example from this model’s parts list
Dead/no power	Microwave fuse	Us pressed steel microwave fuse 3B74133Q
Runs/no heat	High-voltage diode	Microwave high-voltage diode 6021W3B001V
Won’t start with door closed	Door interlock switch	Microwave door interlock switch 6600W1K001Q
Turntable not rotating	Turntable motor	Microwave turntable motor 6549W1S013H
Poor venting	Grease filter/charcoal filter	Grease filter 5230W1A012E, lg microwave charcoal filter 5230W1A003A

Why it matters

Microwave/hood combos use door interlocks and thermal protection to prevent unsafe operation. When a fuse blows or an interlock switch fails, the microwave may go dead or refuse to run; fixing the root cause prevents repeat failures.

On the Kenmore Elite microwave/hood combo, the model number label is on the oven front; you can also find the model and serial number plate at the upper side of the cavity front (the front edge of the opening when you open the door). Use that full model number to match parts and manuals for 72180822500.

Where to look (fast checklist)

• Open the microwave door and look along the front frame of the cavity opening (upper area).
• Check the oven front for the model number label.
• Look for a plate or sticker that lists both Model and Serial.
• Write the model number exactly as shown (all digits).
• Record the serial number too; it helps identify production variations.

What the label typically looks like

Most Kenmore microwave/hood combos use a printed plate or sticker with fields like:

Label field	What it’s used for
Model number	Ensures the correct diagrams and replacement parts
Serial number	Helps confirm version and manufacturing run
Electrical ratings	Useful for troubleshooting and safe servicing

Why it matters

Microwave/hood combos often have similar-looking models with different internal parts (door switches, filters, bulbs, motors). Using the exact model number prevents ordering the wrong component and speeds up troubleshooting.

Helpful reference
