For the Kenmore microwave/hood combo model 40180093700, the cooking (microwave output) power is 1,100 watts, and the input power is 1,700 watts. You can confirm both ratings in the 40180093700 owner's manual.

What “watts” means on a microwave

Microwaves are commonly described using two watt ratings:

• Cooking power (output watts): the heating power delivered to food (what most people mean by “microwave watts”).
• Input power (watts used): the electrical power the microwave draws from the outlet.
• Circuit needs: over-the-range microwaves typically require a dedicated 110 to 120V, 60 Hz household circuit.

Kenmore 40180093700 wattage at a glance

Spec	Value	Why you care
Cooking power (output)	1,100 W	Predicts heating speed and cook times
Input power (draw)	1,700 W	Helps with circuit planning and troubleshooting

Why it matters

Using the correct wattage helps us set realistic cook times, compare performance between Kenmore models, and avoid nuisance issues like blown fuses or slow cooking when the microwave shares a circuit with other high-draw appliances.

Related troubleshooting tip

If your microwave runs but does not heat, the issue is usually in the high-voltage system (not the control panel). Use safe, guided troubleshooting steps in why is my microwave not heating.

To silence the keypad beeps on your Kenmore 40180093700 microwave/hood combo, use the Control setup (default settings) menu on the control panel and turn the sound option off. The exact button sequence is listed in the 40180093700 owner's manual.

Quick steps to try

• Touch CONTROL SETUP.
• Scroll through the available options (use the number pads as prompted on the display).
• Find the sound or beep setting.
• Select OFF to mute tones.
• Press ENTER/START to save.
• Test by pressing a few keys; you should no longer hear beeps.

If you still hear beeps

These are the most common reasons the microwave keeps making sounds even after changing settings:

• Child Lock is on; press and hold ENTER/START for more than 3 seconds to toggle it.
• You are hearing end-of-cook tones (some models keep a reminder tone even when key beeps are off).
• The control did not save; repeat the steps and confirm with ENTER/START.
• Power was interrupted; re-set your preferences after restoring power.

What the main buttons do (helpful when navigating settings)

Button	What it’s used for	Why it matters for silencing
CONTROL SETUP	Changes default settings	Where sound options are typically stored
ENTER/START	Confirms a selection	Saves the new sound setting
STOP/CLEAR	Cancels or clears entries	Helps you back out and retry

Why it matters

Silencing tones is useful in open kitchens and at night, but keeping at least some alerts on helps prevent missed cook cycles and reduces the chance of leaving food in the cavity too long.

On the Kenmore 40180093700 microwave/hood combo, the main fuse is typically located behind the top vent grille area, near the control compartment. Access usually starts by removing the upper grille, then removing the small metal cover that shields the fuse and wiring (follow the steps and safety notes in the 40180093700 owner's manual).

Before you access the fuse (important safety)

Microwaves store high voltage even when unplugged. We recommend limiting DIY work to basic access and visual inspection; have a qualified technician handle any high-voltage testing.

• Unplug the microwave (or switch off the breaker) before removing any panels
• Never defeat the door interlock system
• Do not use an extension cord; use a properly grounded outlet
• If a fuse blows repeatedly, stop replacing fuses and troubleshoot the cause

Typical access path on an over-the-range microwave/hood combo

Most Kenmore over-the-range units use a similar layout:

1. Remove the top vent grille (usually a few screws across the top).
2. Remove the screw(s) securing the small metal control-area cover.
3. The fuse is commonly in a clip-style holder on or near the noise filter/line input area.

If your unit is hardwired into cabinetry or you need to remove the microwave from the wall, use the 40180093700 installation guide for the correct mounting and support steps.

What a blown fuse usually means

A blown fuse is often a symptom, not the root problem. Common causes include a door switch issue, a shorted component, or a failing high-voltage part.

Symptom	Common direction	What to check next
Dead display, no lights	Line fuse open	Door switches, wiring, noise filter
Blows when door opens/closes	Interlock problem	Door switch alignment and mounts
Runs but does not heat	High-voltage circuit issue	Diode, capacitor, transformer

Parts that are often involved (when symptoms match)

If troubleshooting points beyond the fuse, these model-compatible parts are commonly involved:

• Microwave door interlock switch 3405-001034 (can cause blowing fuses or no-run conditions)
• Microwave noise filter assembly DE96-00400D (line input filtering; shorts can affect power)
• Microwave high-voltage diode DE91-70063D (heating circuit component)

Why it matters

The fuse protects your Kenmore 40180093700 from overheating and electrical damage. Replacing a fuse without correcting the underlying cause can lead to repeated failures and unsafe operation.

If your Kenmore 40180093700 microwave/hood combo stopped working, the most common causes are a power interruption, an active control lock, a door not fully latching, or a safety device (thermal cut-off or door interlock switch) opening to prevent operation. Start with the quick checks below.

Quick checks first (no tools)

• Confirm the outlet has power (test with a lamp).
• Reset a tripped breaker or GFCI.
• Unplug the microwave for 2 minutes, then plug it back in.
• Make sure the door closes firmly and the latch area is clear.
• Turn Child Lock off: press and hold ENTER/START for more than 3 seconds; steps are in the 40180093700 owner’s manual.

Common causes when it is dead, will not start, or stops mid-cycle

Microwave/hood combos use door safety interlocks and temperature protection. If the door switch circuit does not prove the door is closed, or if an overheat protector opens, the microwave can appear dead or stop during cooking.

• Door interlock switch worn, loose, or misaligned
• Thermal cut-off opened from overheating or restricted airflow
• Loose wiring connection or a failing noise filter

Symptom-to-part checklist (examples for this model)

Symptom	What to check	Example part for this model
Won’t start, intermittent start	Door latch and interlock circuit	Microwave door interlock switch 3405-001034
Stops during cooking, dead until cool	Overheat protection devices	Range thermal cut-off DE47-20034A
Runs but does not heat	High-voltage circuit (service-level repair)	Microwave high-voltage diode DE91-70063D

Why it matters

These components are designed to prevent operation if the door is not safely latched or if internal temperatures rise too high. Keeping airflow clear (clean grease filter, open vent path) helps prevent nuisance shutdowns.

Safety note

Follow the safety precautions in the 40180093700 owner’s manual; do not defeat safety interlocks and do not operate the microwave if the door, hinges, latches, or seals are damaged. High-voltage testing and repairs should be handled by a qualified technician.
