Are all 30 inch wall ovens the same size?
No. “30-inch” wall ovens are grouped by a nominal width, but the exact cabinet cutout width, cutout height, and depth vary by brand and model. For Kenmore model 79030529800, use the cutout and mounting requirements in the 79030529800 installation guide to confirm fit before ordering parts or scheduling installation.
What “30-inch” usually means
Most 30-inch wall ovens are designed to fit a 30-inch class opening, but manufacturers allow small differences for trim overlap, insulation, and airflow.
Common differences you’ll see:
- Cutout width can vary by fractions of an inch
- Cutout height varies more between single, double, and “1 1/2 cavity” designs
- Depth varies based on gas routing, electrical junction location, and rear clearance
- Trim size can hide small gaps, but it cannot fix an undersized cutout
How to measure correctly (before you buy)
Measure the cabinet opening and compare it to the installation specs.
- Measure cutout width at the top, middle, and bottom
- Measure cutout height on both left and right sides
- Measure cutout depth to the back wall (note any protruding gas or electrical connections)
- Confirm you have a properly grounded electrical supply and correct receptacle type
- Verify the oven can be secured with the required mounting brackets
Typical size ranges (quick reference)
These are common ranges for 30-inch class wall ovens; always follow the model-specific installation specs.
| Dimension | Typical 30-inch class range | What can change it |
|---|---|---|
| Cutout width | About 28 1/2 to 30 inches | Trim design, side clearances |
| Cutout height | Varies widely | Single vs double vs 1 1/2 cavity |
| Cutout depth | Often 23 to 25 inches | Gas line, junction box, rear clearance |
Why it matters
A wall oven that is even slightly mismatched to the cabinet cutout can cause installation delays, poor ventilation, or an oven that cannot be secured properly. Getting the cutout dimensions right also helps avoid cosmetic gaps around the trim.
For model-specific details and special cutout scenarios (such as alternate construction openings), follow the 79030529800 installation guide.

Does anyone make a 30 gas wall oven?
Yes. 30-inch gas wall ovens are still made, including models similar in size to the Kenmore 79030529800. The key is matching the cabinet cutout and clearances to your existing opening so the replacement fits and vents correctly.
What to measure before you buy
Use your current oven opening and the installation requirements as your checklist. For the Kenmore 79030529800, the installation guide calls out minimum clearances and cutout dimensions that you should compare against any new 30-inch gas wall oven.
- Measure the cabinet cutout width, height, and depth (opening must be square)
- Confirm the cabinet can support about 150 lb
- Verify you have room for full door swing (at least 19-3/8 inches clearance for complete door opening)
- Confirm gas hookup access (often a 1-1/2 inch hole is used for the gas hookup)
- Check electrical outlet location and grounding (3-prong grounded receptacle)
Typical fit targets for a “30-inch” gas wall oven
“30-inch” describes the nominal width; the actual cutout and overall dimensions vary by brand and model. Use this table to compare your measurements to the requirements in the 79030529800 installation guide.
| What you’re matching | What to compare | Why it matters |
|---|---|---|
| Cutout width | Your cabinet opening vs. new oven cutout spec | Prevents gaps or a no-fit situation |
| Cutout height | Opening height vs. oven cutout spec | Ensures the trim covers the opening |
| Depth and rear clearance | Cabinet depth vs. oven depth | Avoids pinched gas line or wiring |
| Vent location | Where hot air exits | Prevents heat damage and poor airflow |
Why it matters
Gas wall ovens need both gas and electrical power, plus correct venting and clearances. If the cutout, door clearance, or venting does not match, you can end up with overheating, poor baking performance, or an unsafe installation.

What are the most common issues with 79030529800?
For the Kenmore 79030529800 gas wall oven, the most common problems we see are no-heat or slow preheat, uneven baking temperatures, the oven light not working, and control or error-code issues. These symptoms usually trace to the igniter, temperature sensor, gas valve, or control board.
Most common symptoms and what they usually point to
- Oven will not heat or takes too long to ignite: weak or failing igniter
- Bakes unevenly or temperature seems off: temperature sensor drift or calibration needed
- No oven light: burned-out bulb or failed light socket
- Intermittent operation or error codes: control board problem, wiring connection issue
- Smell of gas or no ignition: gas supply issue or gas valve problem (stop and address immediately)
Parts that commonly fix these issues (for this model)
These are frequently replaced parts listed for Kenmore 79030529800:
| Symptom | Likely part | What it does |
|---|---|---|
| No heat / delayed ignition | Frigidaire range oven burner igniter 5303935066 | Lights the bake burner so gas can ignite |
| Temperature inaccurate | Frigidaire range oven temperature sensor 316217002 | Tells the control how hot the oven is |
| No oven light | Range oven light bulb 316538904 | Provides interior light |
| No oven light (bulb OK) | Range oven light socket 316116400 | Powers and holds the bulb |
| No ignition / gas flow issues | White-westinghouse wall oven gas valve 3203702 | Opens to allow gas to the burner |
| Display issues / error codes | Wall oven control board and overlay 318185338 | Runs oven functions and user interface |
Quick checks we recommend before ordering parts
- Confirm the oven is set to BAKE and a temperature is selected; allow a full preheat.
- Watch and listen for ignition; a weak igniter often causes long preheat and no flame.
- If food is consistently under or overdone, try a temperature verification and calibration per the owner's manual.
- For an oven light issue, replace the bulb first; if it still will not light, inspect the socket.
- If an error code appears, match it to the code list and follow the reset and diagnostic steps in Kenmore 790 manual clean wall oven error codes.
Why it matters
Gas wall oven heating problems often start small (slow ignition, uneven baking) and then become a no-heat failure. Addressing the igniter, sensor, or control issue early helps restore safe, consistent cooking performance.
