Kenmore 79048849900 wall oven/microwave combo Parts

On the Kenmore 79048849900 wall oven/microwave combo, the microwave is built into the combination appliance and is not designed to be swapped out as a separate “drop-in” unit. In practice, you either repair the microwave section (controls, door parts, high-voltage components) or replace the full combo assembly.

What you can do instead (most common options)

• Repair the microwave section when the failure is isolated (no heat, door won’t latch, dead display, intermittent operation).
• Replace a failed microwave control if the oven still works but the microwave won’t respond.
• Fix door and latch issues that prevent operation (many microwaves will not run if the door switches do not prove closed).
• Address power and fuse problems if the unit is completely dead.
• Replace the entire combo when multiple major microwave components are failing or the cavity/structure is damaged.

Parts that commonly solve “microwave not working” symptoms

If your microwave section will not start, stops when the door moves, or acts like the door is open, these parts are frequent fixes:

Symptom	What to check first	Example part for this model
Won’t start, acts like door is open	Door interlock switch and latch parts	Microwave door interlock switch 5304493153
Door won’t open or won’t latch smoothly	Door release lever and latch body	Lever 5304485407
No heat (but runs)	High-voltage components (service recommended)	Microwave high-voltage transformer 5304473321

Safety and service guidance (important)

Microwave high-voltage circuits can store dangerous energy even when unplugged. For “runs but no heat,” burning smells, arcing, or repeated fuse blowing, we recommend professional service.

Also, if the microwave light, cooling fan, or turntable will not operate, our guidance follows the troubleshooting steps in the 79048849900 use & care guide; check the outlet and breaker/fuse first, then move to component diagnosis.

Why it matters

Combo units share a cabinet, controls, and mounting system; that integrated design is why the microwave is typically repaired as a section rather than replaced as a standalone appliance. Repairing targeted parts often restores operation at a much lower cost than replacing the full wall oven/microwave combo.

The microwave in Kenmore model 79048849900 is about 1.7 cubic feet in capacity. For the exact capacity and any model-variant notes, we recommend confirming the specification in the 79048849900 use and care guide.

How to confirm the capacity on your unit

We use the capacity to help match accessories and understand cooking performance. The most reliable place to confirm it is the model’s documentation.

• Check the “Microwave/Wall Oven Features” section in the 79048849900 use and care guide
• Look for a “Specifications” or “Product record” area (often near the front)
• Compare your full model number on the serial plate to the manual’s model list
• If your combo has multiple microwave settings, capacity stays the same but usable space can feel different with racks or turntables installed

Why capacity matters

Microwave capacity affects what fits inside and how evenly food heats, especially with larger cookware.

• Larger dishes and taller containers fit more easily
• Reheat and sensor-cook performance is more consistent when cookware matches cavity size
• Some accessories (racks, trays, covers) are sized by cavity dimensions

Yes. On the Kenmore 79048849900 microwave, the practical “reset” is clearing the control and restoring settings after a power interruption: press Stop/Clear to cancel a program, then reset the clock per the 79048849900 owner's manual.

Quick reset options that work most often

• Cancel a cooking program: Press Stop/Clear once (press twice to cancel during cooking).
• Clear a wrong entry: Press Stop/Clear to erase the mistake and reprogram.
• After a power outage: Press Stop/Clear, then set the clock again.
• Hard reset (power cycle): Turn the breaker off for about 1 minute, then back on; re-set the clock.
• If the display counts down too fast: Turn off Demonstration Mode (Demo mode makes the timer run rapidly).

How to reset the clock after power is restored

If power to the microwave is interrupted, the display can prompt you to press Clear and set the clock. Use this sequence:

Task	What to press	What you should see
Clear the prompt	Stop/Clear	A “:” or time-of-day screen state
Enter clock mode	Clock (or Clock pad)	Ready for time entry
Set time	Number pads, then Clock again	Correct time displayed

When “resetting” is not the right fix

Some symptoms point to a door-safety or power issue, not a settings problem.

• Door won’t start cooking or stops when closing the door: inspect the latch area; a failed microwave door interlock switch 5304493153 can prevent operation.
• Unit appears dead: check the outlet, house breaker, and any internal fuse (microwave service should be done by a qualified technician).
• Door does not close properly or seals are damaged: stop using the microwave until it is inspected.

Why it matters

Microwaves use safety interlocks and programmed controls; clearing the control with Stop/Clear restores normal operation after mistakes or power loss, while door and power problems require a different repair path.

Yes. The Kenmore 79048849900 is a built-in wall oven/microwave combo that combines an upper microwave with a lower wall oven in one cabinet, using separate controls and safety door latches. For feature details and operation, use the 79048849900 use & care guide.

What you get in a combo unit

A wall oven microwave combo is designed to save cabinet space while giving you two cooking cavities.

• Upper microwave with door latches and a turntable
• Lower wall oven with bake and broil functions
• Electronic controls with clock and kitchen timer (features vary by model)
• Oven venting and adjustable oven racks

Quick comparison: combo vs. separate appliances

Option	Space use	Cooking flexibility	Typical install complexity
Wall oven/microwave combo	One cutout for both	Two cavities in one frame	Medium to high
Separate wall oven + countertop microwave	Two locations	Flexible placement	Low
Separate wall oven + built-in microwave	Two cutouts	Flexible pairing	High

How to confirm what your model includes

We recommend matching what you see on your unit to the feature list in the manual.

• Check for an upper microwave door with a see-through window
• Look for a microwave control panel and an open door button
• Confirm the lower oven has racks, interior lights, and a large window
• Verify the model number on the serial plate matches 79048849900

Why it matters

Combo units share a single cabinet and electrical installation, so identifying your exact configuration helps you choose the right replacement parts (like an oven light bulb, temperature sensor, or control board) and follow the correct operating and cleaning instructions.

Most Kenmore microwaves, including the microwave in the Kenmore 79048849900 wall oven/microwave combo, typically last 9 to 10 years with normal household use. Heavy daily use, running the microwave empty, and poor ventilation shorten lifespan; consistent cleaning and correct operation help it reach the full range.

What affects microwave lifespan most

• Daily run time: multiple long heating cycles per day wear components faster
• Running empty: operating with no food inside overheats internal parts and shortens magnetron life (avoid this)
• Door use: slamming the door or a misaligned latch stresses safety interlocks
• Ventilation and heat: blocked airflow and built-in cabinet heat buildup accelerate failures
• Cleaning habits: grease and food debris can cause arcing and odor issues

Signs it is nearing end of life (or needs repair)

• Food takes noticeably longer to heat than it used to
• Loud buzzing/humming that is new or getting worse
• Display or keypad becomes intermittent
• Door does not close smoothly or you have to push hard to start
• Burning smell, arcing, or repeated blown fuses

Quick checks and what they point to

Symptom	Common cause	What we recommend
Won’t start when door closes	Door latch or interlock issue	Inspect the latch area; consider the microwave door interlock switch 5304493153 if the switch tests bad
Runs but heats poorly	Magnetron or high-voltage circuit wear	Stop using if performance drops sharply; have a technician diagnose
Completely dead	Power supply, fuse, wiring	Check breaker first; if it repeats, service is needed

Why it matters

A microwave that is run empty or has a door-interlock problem can fail early and may not operate safely. Following the operating and care guidance in the 79048849900 use and care manual helps prevent the most common avoidable failures.

On the Kenmore wall oven/microwave combo model 79048849900, the model and serial number are printed on the serial plate located along the interior side trim, and it’s visible when you open the oven door. Use the location diagram in the 79048849900 owner's manual to spot it quickly.

What to look for on the label

The serial plate typically includes both identifiers you may need for parts and service.

• Model number (for example, 79048849900)
• Serial number (unique to your unit)
• Electrical ratings (common on appliance data plates)
• Manufacturing information (varies by unit)

Quick steps to find it

1. Open the lower oven door.
2. Look along the interior side trim (the vertical trim area just inside the oven frame).
3. Use a flashlight and read the plate straight on.
4. Write down the model and serial number for future reference.

Why the model number matters

We use the model number to match the correct Kenmore parts and diagrams for your exact configuration (oven controls, door hardware, and microwave components). It also helps avoid ordering a similar-looking part that does not fit.

Common label locations (if it’s hard to see)

If the plate is dirty, painted over, or partially hidden, these checks help.

Check	What to do
Grease or residue	Wipe gently with a damp cloth; avoid soaking the label
Door position	Open the door fully and look from the side
Lighting	Shine a flashlight across the trim to make the print stand out

If the microwave section of your Kenmore 79048849900 wall oven/microwave combo stopped working, the most common causes are a power interruption that erased the program, an active control lock, or a door-switch safety circuit problem. Start with a reset and basic checks from the 79048849900 owner's manual.

Quick checks we recommend first

• Unplug the unit (or switch the breaker off) for 5 minutes, then restore power.
• If the display shows a prompt to set the clock after power returns, press Stop/Clear and reset the clock.
• Make sure Child Lock is not enabled (it disables the control panel).
• Open and firmly close the microwave door; a mis-latched door can prevent operation.
• Check the home breaker and any fuse feeding the wall oven/microwave combo.

What to look for based on symptoms

Symptom	What it usually points to	What we do next
Display is blank, no interior light, no fan	No power to unit, blown fuse, wiring issue	Verify breaker, then inspect power connections
Display works but won’t start cooking	Door not sensing closed, control lock, keypad issue	Check lock setting, then door latch and switches
Starts then stops when door moves	Loose or failing interlock switch	Inspect/replace door interlock components

Parts that commonly fix “won’t run” problems

If your checks above don’t restore operation, these model-compatible parts are common fixes:

• Microwave door interlock switch 5304493153 (prevents operation unless the door is fully closed)
• Microwave latch body 5304503439 (helps the door engage the interlock system)
• Microwave door release lever 5304485407 (supports proper latching and release)

Why it matters

The microwave uses a door-interlock safety system; if the door is not latching perfectly, the unit will refuse to run. Also, after a power interruption the cooking program can be erased and the clock must be reset for normal operation.
