A combo wall oven is a built-in unit that combines two cooking appliances in one cabinet opening, typically a microwave on top and a traditional wall oven below. Your Kenmore Elite 79048802100 is a microwave and wall oven combination designed to be installed as a single, integrated appliance.

What you get with a wall oven/microwave combo

A combination unit is meant to save space while giving you two separate cooking cavities with different functions.

• Microwave compartment for quick reheating and fast cooking
• Wall oven compartment for baking and roasting
• Single built-in installation that fits one cabinet cutout
• Separate controls and safety systems for each cavity
• Shared electrical and mounting requirements for the full unit

Installation basics that define a “combo” unit

Because it is one integrated appliance, the installation requirements apply to the full assembly, not just the oven or just the microwave.

• The cabinet base must support 350 lb (159 kg).
• Plan at least 21 in. clearance in front for the door when open.
• The cutout depth (often called a critical dimension in the guide) affects trim fit and can contribute to noise on convection models.
• This unit is not approved for stackable or side-by-side installation.

For the exact cutout and electrical requirements for the 79048802100, use the installation guide.

Quick comparison: combo vs. separate appliances

Setup	What it means	Typical reason to choose it
Combo wall oven	Microwave + wall oven in one built-in frame	Saves cabinet space; cleaner built-in look
Separate wall oven + countertop microwave	Wall oven built-in; microwave sits on counter	Lower install complexity; flexible placement
Separate built-in microwave + wall oven	Two built-in appliances in separate cutouts	More layout flexibility; can place at different heights

Why it matters

Knowing you have a true combo unit helps you plan the right cabinet cutout, clearance, and electrical supply, and it also ensures you order parts that match the integrated design of the Kenmore Elite 79048802100.

If you need replacement parts for either cavity, you can order model-matched parts from the list for 79048802100, or search by model on Sears PartsDirect.

For the Kenmore Elite 79048802100 wall oven/microwave combo, the most reliable “reset” is a power reset: turn the unit off at the breaker for 1 to 2 minutes, then restore power and re-set the clock. For model-specific control steps, follow the owner's manual.

Quick reset options (start here)

• Power reset (recommended): Switch the circuit breaker OFF for 1 to 2 minutes, then ON.
• Control lock check: If the keypad seems unresponsive, turn off any control lock feature per the owner's manual.
• Clear a stuck key condition: Wipe the keypad dry and press each key once to ensure none are physically stuck.
• After reset: Re-enter time of day and test a simple cook cycle with a cup of water.

If the microwave still will not run

A reset helps only if the issue is a temporary control glitch. If the display is normal but the microwave will not start, focus on door-safety and power-protection parts.

• If the door does not close and latch smoothly, inspect the latch pieces such as the microwave latch body 5304470548 and microwave door latch hook 5304470547.
• If the unit is completely dead (no display), a blown fuse is common; check the microwave fuse 5304480634.
• If the door closes but the unit will not run, a failed interlock can prevent operation; check the microwave door interlock switch 5304493153.

What a reset can and cannot fix (at a glance)

Symptom	Reset likely helps?	What to check next
Display frozen or acting erratic	Yes	Power reset; then test keypad
No heat but it runs	No	Magnetron, high-voltage components
Completely dead (no display)	Sometimes	Fuse, power supply, wiring
Won’t start when door is closed	No	Door latch and interlock switches

Why it matters

The microwave section uses door interlocks and protective devices to prevent operation when the door is not fully latched. A “reset” will not bypass those safety circuits; it only clears temporary electronic control issues.

For the Kenmore Elite 79048802100 wall oven/microwave combo, the microwave is built into the combination unit, so it is not replaced as a separate “drop-in” appliance. In practice, you either repair the microwave section (controls, door switches, fuse, etc.) or replace the entire combo unit; see the installation guide for how the unit is installed as one assembly.

What you can do instead (most common options)

• Repair the microwave section by diagnosing the failed component (door switch, fuse, control board, latch parts).
• Repair the oven section if the issue is actually in the lower oven (bake, convection, temperature sensing).
• Replace the full combo unit if the microwave cavity or major structure is damaged.
• Confirm the symptom first (no heat, no power, door won’t latch, trips breaker) because the fix changes.

Parts that commonly solve “microwave not working” symptoms

If your microwave won’t run, won’t heat, or acts dead, these model-compatible parts are frequent fixes:

• Microwave door interlock switch 5304493153
• Microwave fuse 5304480634
• Frigidaire microwave electronic control board 5304480656
• Microwave door latch hook 5304470547
• Microwave latch body 5304470548

Quick symptom-to-part guide

Symptom	Most likely area	Example part on this model
Runs but will not start when door closes	Door interlock circuit	5304493153
Completely dead (no display)	Fuse or control	5304480634, 5304480656
Door will not stay closed	Latch components	5304470547, 5304470548

Why it matters

Combo units like the Kenmore Elite 79048802100 are installed and secured as a single appliance assembly (cabinet cutout fit, mounting screws, anti-tip screws, and electrical junction box connection). That design is why “swapping just the microwave” is not handled like replacing a countertop microwave.

Safety and installation notes we follow

• Disconnect power at the junction box before any electrical checks.
• The unit is heavy; door removal and handling require a firm grip and safe support.
• Anti-tip mounting screws must be installed to prevent tipping when the door is open.

If you need to order the correct replacement parts for the microwave section, use the parts list for model 79048802100 or search by model number on Sears PartsDirect.

If the microwave portion of your Kenmore Elite wall oven/microwave combo model 79048802100 stopped working, the most common causes are a loss of power to the unit, a blown internal fuse, a door interlock problem, or a failed electronic control. Start with a safe power reset and basic door checks, then move to fuse and switch diagnostics using the owner's manual.

Quick checks we recommend first

• Confirm the unit has power (check the breaker and that the oven is not on a tripped circuit).
• Unplug the unit (or switch off the breaker) for 5 minutes, then restore power to reset the control.
• Make sure the microwave door closes firmly and latches smoothly; do not slam the door.
• Check for a stuck or unresponsive keypad button on the control panel.
• If the display is dead or the unit is completely unresponsive, suspect an internal fuse or control issue.

Parts that commonly cause a “dead” microwave

These parts are commonly involved when the microwave won’t run, won’t heat, or appears to have no power:

Symptom	Most likely area	Example part on this model
No display, no response	Line protection	Microwave fuse 5304480634
Runs only with door held, or won’t start	Door safety circuit	Microwave door interlock switch 5304493153
Display works but functions are erratic	Control electronics	Frigidaire microwave electronic control board 5304480656

Why the door switches matter

Your microwave uses door interlock switches to prove the door is closed before it will run. If a latch is worn, misaligned, or a switch fails, the microwave can stop working even though the oven portion still operates.

Safety and installation-related notes

• Disconnect power before any inspection or electrical testing.
• This appliance must be properly grounded; the installation guide covers grounding and junction box connection requirements.
• If the unit was recently moved or installed in cold conditions, allow it to sit in its final location for at least 3 hours before powering it on (this helps protect electronic controls).

When replacement parts make sense

Replace a part when the symptom is consistent and testing confirms failure.

• Fuse: replace only after finding the cause of the blow.
• Interlock switch: replace if it fails continuity tests or shows heat damage.
• Control board: replace if power is present but outputs and logic are incorrect.
