How do I reset a Kenmore microwave?
To reset your Kenmore microwave/hood combo model 72180529500, unplug it (or switch off the breaker) for about 1 minute, then restore power and set the clock. This clears most control glitches and returns the keypad to normal operation.
Quick reset steps (recommended)
- Press STOP/CLEAR once to cancel any active cooking cycle.
- Unplug the microwave or turn OFF the circuit breaker.
- Wait 60 seconds (2 minutes if the display stays lit).
- Restore power.
- Re-set the clock and test with a 1-cup water heat test.
What to try if the microwave still will not run
Many “needs a reset” complaints are actually a door, power, or control condition.
- Make sure the door is fully closed and latched.
- Confirm you pressed START after entering a cook time.
- If you were using the kitchen timer, press STOP/CLEAR to cancel it.
- Check the home circuit breaker or household fuse.
- Try a different outlet (the unit needs a properly grounded 3-prong outlet).
Troubleshooting guide: symptom to check
| Symptom | Most likely check | What we do next |
|---|---|---|
| Display is blank | No power at outlet, breaker tripped | Restore power, then do the 60-second reset |
| Display works, won’t start | Door not latched, cycle not canceled | Press STOP/CLEAR, re-close door, press START |
| Runs but no heat | Heating circuit issue | Use the heating troubleshooting steps in the manual |
Why it matters
A power reset clears a “stuck” control state, but it also helps us confirm whether the issue is power supply, door interlock operation, or a heating-system problem. If the microwave runs but does not heat, focus on heating diagnostics instead of repeated resets.
For model-specific control and troubleshooting details, use the 72180529500 owner's manual. For mounting and power connection requirements, use the 72180529500 installation guide.

How much clearance for microwave above stove?
For Kenmore model 72180529500 (over-the-range microwave/hood combo), plan for at least 30 inches of clearance from the cooking surface to the bottom of the cabinet/microwave installation area. This minimum spacing helps protect the microwave, supports proper ventilation, and keeps the unit at a safe working height; see the 72180529500 installation guide.
Minimum clearances to follow
Use these baseline measurements during layout and mounting:
- 30 inches minimum from the cooking surface to the bottom of the upper cabinet (the microwave mounts under this cabinet)
- 30 inches minimum cabinet opening width for the microwave to fit properly
- Mount to a flat, vertical wall with adequate structure (studs and proper wall material)
- Ensure the upper cabinet and rear wall can support 150 lb, plus the microwave and any items stored above
Quick reference table
| Measurement | Minimum for 72180529500 | What it affects |
|---|---|---|
| Cooking surface to bottom of upper cabinet | 30 in. | Heat clearance and safe mounting height |

Where is the fuse on a Kenmore microwave model 72180529500?
On the Kenmore microwave/hood combo model 72180529500, the main microwave fuse is typically mounted on or near the noise filter/control area behind the top grille, close to where the power cord enters the unit. Access usually starts by removing the top grille screws and sliding the grille off.
Before you access the fuse (important safety)
Microwaves store high voltage even when unplugged, so we treat fuse access as an electrical repair.
- Unplug the microwave or switch off the circuit breaker
- Confirm the display is off
- Use a stable step stool and have a second person help if needed
- Do not touch any high-voltage components (capacitor, diode, magnetron area)
- If you see burned wiring or melted plastic, stop and schedule service
For model-specific cabinet access and fastener locations, follow the 72180529500 installation guide.
How to get to the fuse on this over-the-range style
Most Kenmore over-the-range units like 72180529500 use this access path:
- Remove the top vent grille (usually 2 screws across the top edge).
- With the grille off, locate the control panel mounting screw(s).
- Tilt the control panel forward to expose the wiring area.
- Look for a small ceramic or glass fuse in a clip holder near the incoming power leads.
What the fuse location is near
| What you see | What it helps you identify |
|---|---|
| Power cord entry area | Fuse is commonly close by to protect the line circuit |
| Control board housing | Fuse is often mounted on the noise filter or line input side |
| Fuse clip holder | The fuse snaps into spring clips (no threads) |
If the fuse is blown, check the common causes first
A blown fuse is often a symptom, not the root problem. Common causes include:
- Door not closing fully or a failed door switch
