Kenmore 40180082700 microwave Parts

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.

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.

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.
