What was the size of the Kenmore 79048033801 oven?
For Kenmore model 79048033801, the “size” is typically the cabinet width class: it installs as either a 27-inch or 30-inch built-in electric wall oven, depending on the exact configuration. The installation guide lists the required cutout and minimum opening dimensions used to fit the oven safely.
Use these dimensions to confirm your cabinet opening before ordering trim, planning a remodel, or pulling the oven for service. We recommend matching your cabinet cutout to the specs in the 79048033801 installation guide.
These are the key measurements you will see referenced for 27-inch and 30-inch single wall ovens:
- Cabinet cutout width: 27 inches or 30 inches class
- Cutout depth (critical): typically around 23 1/2 inches
- Overall/trim-related widths: commonly around 29 9/16 inches (varies by configuration)
- Minimum front clearance for door when open: 21 inches
- Support requirement: base must support 300 lb (27-inch) or 375 lb (30-inch)
If you are trying to confirm the physical size of the oven already in your home (not just the cutout class), measure these points:
- Cabinet opening width (inside edge to inside edge)
- Cabinet opening height (top to bottom of cutout)
- Cutout depth (front of cabinet to back wall)
- Front trim width/height (outermost visible frame)
- Door clearance (space in front for the door swing)
| What you’re checking | 27-inch class | 30-inch class |
|---|---|---|
| Cabinet cutout width class | 27 inches | 30 inches |
| Minimum base support | 300 lb | 375 lb |
| Minimum front clearance (door open) | 21 inches | 21 inches |
Wall ovens are sized by the cabinet cutout they fit. Using the correct 27-inch or 30-inch installation dimensions prevents trim gaps, overheating from poor spacing, and fit issues that can make servicing difficult.

How to unlock a Kenmore Elite oven?
To unlock the control lock on your Kenmore Elite wall oven model 79048033801, press and hold the Oven Lockout pad for 3 seconds until “Loc” clears; the “DOOR LOCKED” indicator may keep flashing until the door fully unlocks. See the steps in the 79048033801 owner's manual.
- Make sure the oven is not running a bake, broil, or self-clean cycle.
- Press and hold the Oven Lockout pad for 3 seconds.
- Listen for a beep; “Loc” should clear from the display.
- Wait while the door latch motor finishes; “DOOR LOCKED” can flash until the latch opens.
- Try opening the door only after the indicator stops flashing.
These checks fix most “stuck locked” situations on electric wall ovens like the 79048033801.
- Give it time: the latch can take a minute or two to fully retract.
- Let it cool: if the oven is hot (or just finished a clean cycle), the lock can stay engaged until temperatures drop.
- Reset power: turn the breaker OFF for 1 minute, then ON; retry the 3-second unlock.
- Check for a latch or cooling issue: if the oven overheats or the latch does not move, the lock can remain engaged.
- Inspect common related parts: a failed cooling fan or overheat protection can contribute to lock problems.
| Symptom you notice | Common area to check | Example part for this model |
|---|---|---|
| Oven stays locked after cooling | Door latch system, control logic | Use the 79048033801 owner's manual to identify the latch circuit and test points |
| Oven runs very hot around the control area | Cooling airflow | Range oven cooling fan assembly 318073028 |
| Oven shuts down or acts erratic when hot | Overheat protection | Range high-limit thermostat 318004902 |
The Oven Lockout feature is designed to prevent the oven from being turned on and to automatically lock the door; unlocking correctly protects the latch mechanism and helps avoid damage to the door, hinges, and glass.

What is the error code fo on a Kenmore oven?
On Kenmore Elite wall oven model 79048033801, a display that looks like “FO” is treated as an F-code fault from the electronic oven control. Our recommended first step is to clear the fault with STOP/CLEAR; if the fault returns, the oven needs diagnosis of the control system.
- Press STOP/CLEAR to stop the beeping and clear the display.
- Reprogram the oven and try a basic cycle such as Bake.
- If the fault reappears, record the exact code shown.
- Turn the oven off and avoid continued use until the issue is corrected.
- Use the troubleshooting steps in the 79048033801 owner's manual.
The owner’s manual groups these as control-detected faults:
| Display behavior | What it indicates | What to do |
|---|---|---|
| Beeps and shows an F code (example: F11) | Electronic control detected a fault condition | Clear with STOP/CLEAR, reprogram, and if it returns record the code and arrange service |
These are the most common areas checked when an F-code keeps returning on an electric wall oven:
- User interface or keypad inputs (stuck key behavior)
- Electronic oven control board connections
- Wiring harness and connectors for looseness or heat damage
- Power supply stability and proper grounding
An F-code means the control is detecting a condition that can interrupt cooking or cause repeated beeping. Clearing the code and confirming it does not return helps prevent unreliable operation and protects the oven’s electronic control system.
