Are all 30 inch wall ovens the same size?
No. “30-inch” wall ovens are grouped by a nominal width, but the actual cabinet cutout width, cutout height, and overall depth vary by brand and model. For the Kenmore 79030179401 gas wall oven, use the cutout dimensions and clearance requirements in the 79030179401 installation guide to confirm fit before ordering or installing.
Manufacturers use “30-inch” as a category, not an exact measurement. Differences show up most often in the cabinet opening and how far the oven projects past the cabinet face.
Common variables that change between “30-inch” models:
- Cutout width tolerance (small differences can prevent installation)
- Cutout height (single vs. double ovens, trim styles)
- Overall depth and required rear clearance for gas and electrical
- Door swing clearance (space needed in front of the oven)
- Vent location and airflow requirements
Your installation instructions call out key requirements that affect whether another “30-inch” oven will fit the same opening.
Key points to verify:
- The oven support surface must be solid and level, and able to support 150 lb
- Allow at least 19-3/8 in clearance for the oven door to open completely
- Some installations allow height adjustment using side extension panels (each position changes height about 1/2 in)
| What to measure | Where to measure | Why it matters |
|---|---|---|
| Cutout width | Inside cabinet opening | Prevents binding or gaps |
| Cutout height | Inside cabinet opening | Ensures trim covers opening |
| Cutout depth | Front of cabinet to back wall | Avoids pinched gas line or wiring |
| Front clearance | From cabinet face outward | Door swing and safe access |
A wall oven that is “30-inch” wide can still fail to fit if the cutout height is different, the depth is longer, or the door needs more clearance. Matching the installation specs avoids cabinet modifications and helps ensure safe venting and proper combustion airflow.

Does anyone make a 27 inch gas wall oven?
Yes. 27-inch gas wall ovens exist, but they are less common than 30-inch models. For Kenmore model 79030179401, the installation guide shows a cabinet cutout width around 24 inches minimum and an overall oven width around 27-1/2 inches maximum, which aligns with the “27-inch class” built-in size. See the 79030179401 installation guide for the exact cutout and clearance requirements.
Manufacturers often market wall ovens by a nominal size (like 27-inch), while the actual appliance width and the required cabinet opening can differ.
Common sizing details to compare:
- Overall oven width (outside-to-outside)
- Cabinet cutout width (the opening in the cabinet)
- Height adjustment/trim overlap (can affect fit)
- Door swing clearance (space needed in front)
- Gas hookup location (hole placement and access)
| Item to compare | Typical “27-inch class” wall oven | Kenmore 79030179401 (from install guide) |
|---|---|---|
| Overall width | About 27 inches | Up to about 27-1/2 inches |
| Cutout width | Often about 24 inches | About 24 inches minimum |
| Door clearance | Varies by model | About 19-3/8 inches to open fully |
Before buying any replacement wall oven (Kenmore or another brand), we recommend matching these measurements to your cabinet:
- Measure the existing cutout width, height, and depth
- Confirm gas supply location and access
- Verify electrical grounding requirements (most units use a grounded plug)
- Check venting location and keep it unobstructed
- Confirm the cabinet can support the oven weight (many require a solid support surface)
A wall oven can be advertised as “27-inch,” but the cabinet cutout and trim requirements determine whether it installs safely and looks right. Using the installation dimensions for model 79030179401 helps prevent gaps, binding doors, and unsafe venting or gas hookup access.

How to find wall oven model number?
On the Kenmore gas wall oven model 79030179401, the model number is printed on the serial plate located along the interior side trim and is visible when you open the oven door. We recommend writing down the model and serial number before ordering parts or scheduling service.
The serial plate is typically on the left-side inner trim of the oven frame.
- Open the oven door fully and look along the vertical trim inside the frame
- Check the left interior side trim first (most common location)
- Use a flashlight; the plate can be hard to read in low light
- Record the model number, serial number, and any lot number/letter shown
- Take a clear photo so you can zoom in later
Besides the model number, the serial plate can include details that matter when selecting parts.
| Serial plate item | Why it matters |
|---|---|
| Model number | Ensures diagrams and parts match your exact oven |
| Serial number | Helps confirm production details for correct replacement parts |
| Lot number/letter | Can narrow down version changes within the same model |
| Fuel and pressure info | Confirms how the oven was set up from the factory |
- Wipe the trim gently with a damp cloth and mild cleaner; dry it completely
- Avoid scraping; you can damage the printed information
- If the plate is faded, take multiple photos from different angles
Kenmore wall ovens can have similar-looking designs across model series. Using the exact model number (79030179401) helps us match the correct control board, igniter, temperature sensor, and other parts the first time.
