What are the most common issues with 72180822500?
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
- Confirm the outlet has power (try a small appliance).
- Unplug the microwave for 2 minutes, then restore power.
- Check that the door closes firmly and the latch area is clean.
- Inspect and clean the hood filters; replace if damaged.
- 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.
