Kenmore 79048853900 wall oven/microwave combo Parts

Kenmore microwaves are a solid choice for most homes because they typically deliver dependable everyday heating and practical features at a good value. For the Kenmore 79048853900 wall oven/microwave combo, long-term satisfaction comes down to correct use, ventilation, and keeping key door and safety components in good condition (see the 79048853900 owner’s manual).

A built-in microwave like the one in model 79048853900 is “good” when it heats evenly, runs quietly, and operates safely with a properly closing door.

Common strengths we see with Kenmore microwave systems:

• Good value for a built-in combo unit
• Straightforward controls and everyday cooking performance
• Normal magnetron cycling at lower power levels (you may hear it turn on and off)
• Typical warmth on the exterior during cooking
• Condensation inside the cavity is normal depending on humidity and food moisture

Use these simple habits to get the best results and avoid preventable failures:

• Always cook with food in the microwave; running empty can stress components
• Never operate without the turntable and support installed
• Keep foil at least 1 inch away from interior surfaces if you use small shielding pieces
• Use only microwave-safe plastics, glass, and coverings
• Do not allow children to lean on or swing from the door

If heating becomes inconsistent or the unit will not run, these parts are commonly involved:

Microwave performance and safety depend heavily on door sealing and interlock operation. Using the correct cookware and operating practices from the manual reduces stress on the magnetron and control system, which helps the microwave last longer.

Yes. We still support Kenmore appliances with replacement parts; the key is matching parts to your exact model number (for this unit, Kenmore 79048853900). Many Kenmore appliances were built by major manufacturers, so OEM-equivalent parts remain available when you search by model and part type in the 79048853900 owner's manual.

Use your model number first, then narrow by symptom or part category.

• Confirm the full model number from the rating label: 79048853900
• Identify whether the issue is in the oven or microwave section (combo units have separate systems)
• Look up the part by description (example: light bulb, temperature sensor, door switch)
• Compare your old part markings to the listing (part number and photos)
• Check availability before ordering, especially for control boards and assemblies

These are examples of parts available for Kenmore 79048853900 that often solve everyday problems:

Kenmore model numbers identify the exact design and the manufacturer-built platform behind it. That is why searching by 79048853900 is more accurate than searching by “Kenmore wall oven microwave combo” alone; it prevents ordering a similar-looking part that will not fit.

If your oven or microwave is showing an error code, use a Kenmore wall oven error code reference to pinpoint the failing circuit before replacing parts.

• Start with the exact code and when it appears
• Reset power for 1 minute to confirm it returns
• If it returns, follow the code guidance and test the related component

For Kenmore model 79048853900, the built-in microwave/wall oven combo is designed for a 30-inch cabinet cutout width. For exact overall appliance dimensions (width, height, depth), we recommend confirming the spec table in the 79048853900 installation guide.

The installation guide focuses on cabinet and cutout sizing (the measurements that matter most for fit). Key requirements include:

• Cabinet cutout width (30-inch class): 29 inches (typical cutout width)
• Minimum cabinet width: 30 1/8 inches
• Minimum clearance in front of the unit: 21 inches (for door depth when open)
• Base support requirement: must support 225 lb

Use these steps to get the right numbers for your 79048853900 configuration:

• Check the dimension diagram and spec table in the 79048853900 installation guide.
• Measure the cabinet opening (width, height, depth) and compare to the cutout requirements.
• If trim does not sit flush after install, re-check the cutout depth (often labeled as a critical dimension).
• If you are planning a replacement, measure the existing unit’s face frame and depth from the cabinet front.

Microwave/wall oven combos are sized around the cabinet cutout, not just the appliance box. Matching the cutout width, depth, and required clearances prevents heat buildup, door binding, and trim fit issues.

To reset the electronic oven control on your Kenmore wall oven/microwave combo model 79048853900, clear the control and reboot it: press STOP to cancel any active cycle or error beeping, then turn power to the unit OFF at the breaker for about 1 minute and restore power.

• Press STOP once to clear the display and stop any beeping.
• If the control is unresponsive, switch the oven circuit OFF at the home breaker.
• Wait about 60 seconds (this fully discharges the control).
• Turn the breaker ON.
• Set the clock and try BAKE or BROIL to confirm normal operation.

For model-specific control pad names and display messages, follow the steps in the 79048853900 owner's manual.

The manual’s “Before You Call” guidance for this style of Kenmore control is:

• Press STOP to clear the code and stop the beeping.
• Reprogram the oven.
• If the same fault returns, record the exact code and pursue service.

A repeating temperature-related fault often points to the oven temperature sensor circuit. If you are troubleshooting inaccurate temps or recurring heat errors, the frigidaire range oven temperature sensor 316217002 is a common related part for this model.

A proper reset clears stuck key inputs, cancels a timed or delayed bake, and stops nuisance beeping so you can confirm whether you have a one-time glitch or a repeatable fault that needs a part replacement or service.

On Kenmore wall oven/microwave combo model 79048853900, the most common causes of a microwave that stops working are a power supply problem (outlet, fuse, or breaker), a door-switch/interlock issue, or a failed internal safety device such as a thermal fuse. Use the checks in the 79048853900 use and care manual to narrow it down safely.

• Confirm the display is on; if it is blank, check the house breaker and outlet.
• If power was interrupted, reset the clock; the manual notes the program and time can erase after a power loss.
• If the unit seems “dead” but the outlet is good, suspect an internal fuse or thermal fuse.
• If it runs only with the door held a certain way, suspect the door interlock system.
• If the time counts down unusually fast, check and cancel demonstration mode.

A microwave can stop working to protect you and the appliance. Door interlocks and thermal fuses are designed to shut the unit down if the door is not safely latched or if temperatures get too high.

We do not recommend do-it-yourself internal microwave repairs. The manual’s “Before You Call” section advises checking the outlet, fuse, and/or circuit breaker first; if those are good, service is the safe next step.
