How do I reset a Kenmore microwave?
To reset your Kenmore 72180593400 microwave/hood combo, we recommend doing a simple power reset: unplug the microwave (or turn off the breaker) for about 1 minute, then restore power and set the clock. This clears many control glitches without changing normal settings.
- Power reset (recommended): Unplug for 60 seconds, then plug back in.
- Breaker reset: Turn the microwave circuit breaker off for 60 seconds, then back on.
- Stop/Clear reset: Touch STOP/Clear to cancel an active cooking program or timer.
- Door reset: Open and firmly close the door to ensure it is fully latched.
- Turn the microwave off.
- Unplug the power cord from the grounded outlet (or switch the breaker off).
- Wait 60 seconds.
- Restore power.
- Re-set the clock and test a short heat cycle with a cup of water.
The manual troubleshooting checks for this model focus on basic causes first. Use this checklist:
- Confirm the cord is plugged into a grounded 3-prong outlet.
- Check for a tripped circuit breaker or blown household fuse.
- Make sure the door is closed and latched.
- Press START after setting cook time.
- If you were using the unit as a timer, press STOP/Clear to cancel the Kitchen Timer.
| Symptom after reset | Most likely cause | What to do next |
|---|---|---|
| Display is blank | No power to microwave | Check outlet, breaker, house fuse |
| Display works but won’t start | Door not latched or program not cleared | Close door firmly; press STOP/Clear; try again |
| Runs but no heat | Heating circuit issue | Use why is my microwave not heating for guided checks |
A reset is the fastest way to clear a stuck keypad, interrupted cook cycle, or control logic hiccup. If the unit has no power or repeatedly loses power, the issue is usually electrical supply, a door interlock problem, or an internal fuse.

What is the minimum clearance for a microwave above a range?
For Kenmore model 72180593400, the minimum clearance is 30 inches from the cooking surface to the bottom of the upper cabinet area where the microwave mounts (the installation template positions the unit to meet this requirement). Use the 72180593400 installation guide to confirm your cabinet and mounting-plate measurements.
These are the key spacing rules called out for this over-the-range microwave installation:
- 30 inches minimum from the cooking surface to the bottom of the cabinet area above (minimum vertical clearance)
- 30 inches minimum cabinet opening width
- Install above a range with maximum width of 36 inches
- Mount to a wall with at least one 2 in. x 4 in. wall stud using a lag screw (do not mount to an island or peninsula)
Use this checklist to avoid a misaligned install:
- Measure from the cooktop surface up 30 inches and mark your reference line
- Verify the cabinet opening is at least 30 inches wide
- Confirm the mounting plate and templates are centered and level
- Locate wall studs (typically 16 inches apart) and plan lag-screw placement
- Confirm the upper cabinet and rear wall can support 150 lbs. plus the oven weight and contents
The installation guide’s 30-inch requirement is about heat exposure and safe fit above the cooktop. If you mount the microwave higher than the minimum, you may gain more headroom, but you must still keep the unit securely supported and properly vented.
| Measurement | Minimum for 72180593400 | Why it matters |
|---|---|---|
| Cooktop to mounting height reference | 30 in. | Prevents overheating and ensures safe placement |
| Cabinet opening width | 30 in. | Ensures the microwave fits between cabinets |
| Range width supported | Up to 36 in. | Confirms compatibility with standard ranges |
Correct clearance helps protect the microwave’s internal components (control panel, wiring, and ventilation system) from excess heat and helps the hood fan capture smoke and steam effectively.

What size is an over the hood microwave?
For the Kenmore over-the-range microwave/hood combo model 72180593400, the overall size is 29-15/16 inches wide, 16-7/16 inches high, and 15-3/8 inches deep (door closed). These dimensions match the standard 30-inch over-the-range microwave footprint used above most ranges.
| Measurement | Size |
|---|---|
| Width | 29-15/16 in. |
| Height | 16-7/16 in. |
| Depth (door closed) | 15-3/8 in. |
To avoid fit and venting problems, we recommend checking these items in addition to the microwave’s overall dimensions (see the 72180593400 installation guide).
- Cabinet opening width (most are built for a 30-inch unit)
- Clearance between the cooktop and the cabinet bottom
- Upper cabinet depth and any recessed cabinet bottom (filler blocks may be needed)
- Location of the power supply cord hole in the upper cabinet
- Venting path (roof venting, wall venting, or recirculating)
Most over-the-range microwaves are built around a 30-inch width, with common ranges like:
- Width: 29-7/8 to 30 in.
- Height: 16 to 18 in.
- Depth: 15 to 18 in.
Correct sizing helps the mounting plate line up properly, keeps the unit stable, and prevents issues with cabinet doors, backsplash clearance, and vent duct alignment. It also helps ensure the microwave is positioned safely above the cooking surface.
