Kenmore 40180092700 microwave Parts

For Kenmore microwave/hood combo model 40180092700, we replace the cooktop (over-stove) light by turning off power, removing the bulb cover, installing the correct wattage appliance bulb, then reinstalling the cover and restoring power. Follow the steps in the owner's manual.

Cooktop (over-stove) light bulb replacement steps

• Unplug the microwave or turn off power at the main power supply.
• Remove the bulb cover mounting screws.
• Remove the bulb cover.
• Replace the bulb with a 20-watt appliance bulb (cooktop/night light).
• Reinstall the bulb cover and mounting screws.
• Restore power.

Oven (interior) light vs cooktop light: use the right bulb

This model uses different bulbs depending on which light you are replacing.

Light location	Typical name in instructions	Bulb type (per manual)	Common symptom when burned out
Under the microwave	Cooktop/Night light	20-watt appliance bulb	No light on the stovetop
Inside the microwave	Oven light	40-watt appliance bulb	Interior stays dark when door opens

If you are replacing the interior (oven) light instead

The interior light replacement requires removing the vent grille and the bulb holder screw, then swapping in a 40-watt appliance bulb. Use the exact sequence in the owner's manual so the grille and bulb holder go back correctly.

Why it matters

Using the correct bulb wattage helps prevent overheating and damage to the bulb cover and surrounding plastic parts. Restoring power only after the cover is secured also reduces the chance of electrical shock.

Parts and hardware notes

If the light issue is not the bulb (for example, the light works intermittently when the door moves), a door switch or latch problem can be involved. For this model, common related parts include the microwave door interlock switch 3405-001034 and the microwave door latch housing DE66-00168A. You can order replacement parts for model 40180092700 from the parts list for this model, or search by model number on Sears PartsDirect.

To reset your Kenmore microwave/hood combo model 40180092700, unplug it (or turn off the breaker) for 10 seconds, then restore power. This clears many control glitches and prompts you to reset the clock after an outage; see the owner's manual.

Quick reset options (what to try first)

• Power reset: Unplug for 10 seconds, then plug back in.
• Breaker reset: Turn the circuit breaker off, wait 10 seconds, then turn it back on.
• Clear the keypad: Press STOP/CLEAR twice, then re-enter your cooking settings.
• Unlock controls (if nothing responds): Press and hold ENTER/START for more than 3 seconds to toggle Child Lock.

What you should see after a reset

After power is restored, the display may prompt you to set the clock (especially after a power outage). Once the clock is set, normal cooking functions should return.

Situation	Best “reset” to use	What it fixes
Display frozen or acting odd	Power reset (10 seconds)	Control board glitches, stuck logic
Buttons work but program is wrong	STOP/CLEAR twice	Incorrect entry, cancels a cycle
No response to most keys	Child Lock toggle	Locked control panel
Unit seems dead	Check outlet, breaker, fuse	Power supply issue (not a settings problem)

Why it matters

A reset is the fastest way to rule out a simple control issue before you spend time troubleshooting parts like door switches, thermostats, or high-voltage components.

If it still will not run after resetting

• Confirm the door closes and latches fully (a misaligned door can prevent operation).
• Try a different outlet to rule out a bad receptacle.
• Make sure the microwave is on a dedicated 20-amp circuit to prevent voltage drop.
• If the unit runs but does not heat, use our troubleshooting steps in why is my microwave not heating.
• If you suspect an internal electrical failure, we recommend professional service because microwave high-voltage components can retain a dangerous charge even when unplugged.

For the Kenmore 40180092700 microwave/hood combo, the exact exterior dimensions (width, height, and depth) are listed in the specifications section of the 40180092700 owner's manual. Use those published specs when measuring for cabinet clearance, venting alignment, and mounting height.

How to measure it correctly (so your numbers match the specs)

• Measure width across the front from the left outer edge to the right outer edge.
• Measure height from the bottom of the microwave to the top of the cabinet.
• Measure depth from the back (wall side) to the front-most point (often the door handle area).
• Leave extra space for the power cord and ducting if you vent outside.
• If you are replacing an existing over-the-range unit, measure the mounting bolt spacing and cabinet cutouts too.

Typical over-the-range microwave size range (helpful for planning)

Most over-the-range microwave/hood combos are built to fit standard 30-inch ranges. These typical ranges help you sanity-check your measurements while you confirm the exact specs in the manual:

Dimension	Typical range (inches)	What it affects
Width	29 to 30	Fit between cabinets, alignment over range
Height	15 to 17	Clearance to upper cabinet, mounting height
Depth	15 to 17	Door swing, front clearance, cabinet depth

Why it matters

Getting the right dimensions prevents common install problems like misaligned top mounting bolts, a vent damper that will not open freely, or a microwave that sits too low over the cooktop.

Parts that often come up during a replacement or re-install

If you are re-hanging the unit or correcting fit issues, these model-compatible parts are commonly involved:

• Microwave mounting bolt DE60-20022A (top cabinet mounting)
• Microwave mounting screw DE60-10111A (brackets and trim attachment)
• Microwave vent damper DE72-40022A (helps control backdraft when venting)

If you need to order any of these, you can buy model-specific parts from the parts list for Kenmore 40180092700, or search by model number on Sears PartsDirect.

On Kenmore microwave/hood combo model 40180092700, an E12 code indicates the control is detecting an abnormal sensor input. The most effective first step is a hard reset (power off at the breaker for 1 minute), then confirm whether the code returns; use the 40180092700 owner's manual for your model’s specific operating and safety guidance.

What to do first (safe, practical steps)

• Turn off power at the circuit breaker for 1 full minute.
• Restore power and wait about 1 minute.
• If E12 returns, stop cooking and unplug the unit or switch the breaker off.
• Make sure the door closes firmly and latches normally.
• Check that the vent intake and grille are not blocked by grease buildup.

Common causes that trigger E12 on over-the-range microwaves

E12 is most often tied to a sensor signal that is out of range or not being read correctly.

What can be wrong	What you may notice	What typically fixes it
Humidity/sensor circuit issue	Code appears during sensor cooking	Inspect sensor area and wiring; replace sensor if failed
Cooling airflow restriction	Code appears after heating	Clean filters and vents; restore airflow
Control board input problem	Code returns immediately after reset	Professional diagnosis; control replacement if needed

Parts on this model that can help prevent repeat faults

If the issue is related to airflow and heat buildup, these model-compatible parts are commonly involved:

• Replace a clogged filter with the microwave grease filter DE63-00196A.
• For recirculating installations, replace a saturated filter with the microwave charcoal filter DE63-00367D.
• If sensor cooking is involved, the microwave humidity sensor DE32-60011A is the sensor component used on this model.

Why it matters

When the microwave cannot trust a sensor signal, it can shut down cooking, overrun cook times, or repeatedly fault. Restoring proper airflow and correcting the sensor circuit prevents nuisance errors and protects internal components.

On the Kenmore 40180092700 microwave/hood combo, the internal line fuse is accessed from the top front area behind the vent grille, in the control compartment. Use the 40180092700 owner's manual and 40180092700 installation guide to confirm panel removal and mounting details for your setup.

Safety first (microwave-specific)

Microwaves contain high-voltage components that can hold a charge even when unplugged. We recommend using a qualified technician for internal electrical diagnosis.

• Unplug the microwave or switch off the breaker before removing any panels
• Do not operate the microwave with the outer cover removed
• Do not bypass door interlock switches
• Use a meter rated for household voltage when checking power at the outlet
• Replace a blown fuse only after addressing the cause of the overload

How to reach the fuse on model 40180092700

These steps match the standard access point for this Kenmore over-the-range design: the top vent grille and control compartment.

• Remove the screws securing the top vent grille
• Slide the vent grille off to expose the control area
• Remove the control compartment cover (small metal cover behind the grille)
• Locate the line fuse in its holder inside the control compartment

What a blown fuse usually means

A fuse opens to protect the microwave when there is a short, overload, or door-safety issue.

What you see	What to check next	Common related area
No display, no interior light	Outlet power, breaker, then line fuse	Power supply and line fuse circuit
Fuse blows again quickly	Door switch circuit and wiring	Interlock system
Runs but does not heat	High-voltage circuit components	Diode, capacitor, transformer

Parts that commonly relate to repeat fuse blowing

If the fuse opens again after replacement, these model-matched parts are common suspects:

• Microwave door interlock switch 3405-001034 (door safety circuit)
• Microwave high-voltage diode DE91-70063D (high-voltage rectifier)
• Microwave high-voltage capacitor 2501-001016 (high-voltage circuit)

Why it matters

The fuse is a safety device; replacing it without correcting the underlying short or failing component often leads to another blown fuse and additional damage.
