How big is a Kenmore microwave model 40180082700 in inches?
The Kenmore microwave/hood combo model 40180082700 has outer dimensions of 29 7/8 inches wide x 16 13/16 inches high x 16 inches deep. Use these measurements for fit planning between cabinets and above the range; installation clearances can require additional space.
Dimensions (outer cabinet)
| Measurement | Size (inches) |
|---|---|
| Width | 29 7/8 |
| Height | 16 13/16 |
| Depth | 16 |
What to measure before installation
- Cabinet opening width between the upper cabinets.
- Distance from the wall to the front edge of the cabinet (depth clearance).
- Space above the cooktop for comfortable use and visibility.
- Venting path choice: ducted (top or rear) vs. recirculating.
- Mounting location details such as bracket position and hole pattern.
Installation notes that affect fit
The microwave body size is only part of the planning. The mounting plate, top cabinet holes, and venting configuration determine the final placement.
| Planning item | Why it changes fit |
|---|---|
| Ducted vs. recirculating | Changes where the exhaust outlet must align |
| Wall bracket placement | Controls height and level alignment |
| Top cabinet hole locations | Determines where the unit bolts up |
Why it matters
Correct dimensions prevent cabinet interference, misaligned mounting holes, and restricted airflow for the vent fan. That protects cooking performance and helps the hood vent work properly.

How do I reset my Kenmore microwave?
To reset your Kenmore microwave model 40180082700, unplug it (or turn off the breaker) for 10 seconds, then restore power. This clears many control glitches and is the standard reset method listed in the 40180082700 owner's manual.
Quick reset options (most common)
- Power reset: Unplug the microwave for 10 seconds, then plug it back in.
- Breaker reset: Turn the microwave circuit breaker off, wait 10 seconds, then turn it back on.
- Clear a bad entry: Press STOP/CLEAR twice, then re-enter the cooking instructions.
- After a power outage: Reset the clock when prompted, then reprogram any settings.
What you should see after a reset
Depending on what caused the issue, you may notice one of these behaviors:
| Situation | What happens after power is restored | What to do next |
|---|---|---|
| Minor control glitch | Display returns to normal | Test a simple cook cycle |
| Power outage occurred | Clock prompt appears | Set the clock and retry |
| Keypad confusion | Inputs do not match what you intended | Press STOP/CLEAR twice and re-enter |
If the microwave still will not run
These checks solve the most common “dead” or “won’t start” complaints on over-the-range microwave/hood combos:
- Confirm the outlet has power (test with another small appliance).
- If the outlet is on a wall switch, make sure the switch is ON.
- Make sure the door closes firmly and the seal area is clear of debris.
- Reset the breaker or replace a blown house fuse.
- If the unit shares a circuit with another appliance, move it to its own circuit to prevent voltage drop.
Why it matters
A power reset restores the control board to a known good state and clears temporary faults caused by voltage dips, keypad input errors, or brief outages. It is the safest first step before diagnosing parts like the control panel or door interlock system.

How do I find the model number on my 40180082700?
The model number for your Kenmore microwave/hood combo is printed on the appliance’s rating label; on over-the-range units like model 40180082700, it’s typically found on the inside frame area behind the door. Use the exact model number from that label when ordering parts or checking specs in the owner's manual.
Where to look on a Kenmore microwave/hood combo
Check these common label locations (in order):
- Open the door and look along the oven frame (door jamb) on the left or right side
- Look along the top edge of the cavity opening (just inside the door)
- Check behind the vent grille (top front) if the label is not visible at the door frame
- Look on the side wall of the cooking cavity (less common)
- If the unit was recently installed, check paperwork that came with the microwave and the installation guide
What to write down from the label
We recommend copying the information exactly as shown so you get the right diagrams and replacement parts.
| Label item | What it’s used for | Example format |
|---|---|---|
| Model number | Identifies the correct parts list and manual | 40180082700 |
| Serial number | Helps match production run details | Letters and numbers |
| Electrical rating | Confirms circuit requirements | Volts/amps/watts |
Why it matters
Kenmore microwave/hood combos often share similar styling across multiple models (the manual excerpt lists several related models in the 401.8008X series). Using the exact model number from the rating label prevents ordering the wrong door parts, filters, or controls.
