How to find Whirlpool gas range model number?
For a Whirlpool gas range like model WFG320M0MB0, the model number is printed on a rating label on the range body (not on a removable part). On many freestanding Whirlpool ranges, you can find it by pulling out the bottom drawer (warming drawer or storage drawer) and looking along the frame behind it.
Where to look on a freestanding Whirlpool range
Check these common label locations in this order:
- Behind the bottom drawer: on the frame rail, side wall, or back panel area
- Around the oven door opening: on the front frame when the oven door is open
- On the back of the range: near the gas connection area (you may need a flashlight)
- Under the cooktop edge (less common): along the front lip or side flange
Quick steps to find it fast
- Turn the oven off and let surfaces cool.
- Pull the bottom drawer straight out (lift slightly if it stops on the glides).
- Use a flashlight and look for a white or silver sticker.
- Record the model number and serial number exactly as shown.
What the label usually looks like
| Item on label | Example format | Why you need it |
|---|---|---|
| Model number | WFG320M0MB0 | Ensures correct parts fit |
| Serial number | Letters and numbers | Helps match production version |
| Gas type info | Natural gas or LP | Confirms fuel setup before ordering |
Why it matters
Whirlpool ranges can look identical but use different igniters, oven burners, control boards, and door parts by production run. Using the exact model number prevents ordering the wrong part and avoids repeat repairs.

What size gas line for Whirlpool gas range?
For the Whirlpool WFG320M0MB0 30-inch freestanding gas range, use a 3/4-inch rigid gas supply pipe to the range location; for LP (propane), 1/2-inch minimum piping or tubing is used. Correct sizing prevents weak flames and slow oven preheat.
Recommended gas supply setup
- Run 3/4-inch rigid pipe to the range location for best flow on natural gas
- Use 1/2-inch minimum piping or tubing for LP (propane) supply runs
- Install an approved manual shut-off valve in an accessible location
- Use an approved flexible connector sized and rated for gas appliances
- Have a qualified installer verify leak-free connections before operation
Quick sizing guide
| Fuel type | Supply pipe to range location | Notes |
|---|---|---|
| Natural gas | 3/4-inch rigid pipe | Smaller pipe on long runs can reduce burner performance |
| LP (propane) | 1/2-inch minimum | Confirm regulator and conversion are set for LP |
When line size becomes a problem
- Surface burner flames look small, lazy, or uneven
- Oven takes much longer than normal to preheat
- Flames change when another gas appliance turns on
- Oven burner ignition is delayed or inconsistent
Why it matters
Gas line size affects the volume of gas reaching the range manifold. If the supply is undersized or the run is long, pressure drop can cause poor ignition, unstable flames, and uneven cooking.
Related parts if the gas supply checks out
If the supply and shut-off valve are correct but the oven still struggles to ignite or heat, check the ignition and burner system; common replacements include the igniter, hot surface W11590294 and the oven burner W11220387.

Why is my Whirlpool range broiler not working?
On the Whirlpool WFG320M0MB0 gas range, a broiler that will not heat is usually caused by an ignition problem (weak hot-surface igniter), a gas delivery issue to the broil burner, or a control problem. Start with simple checks, then test the ignition and burner components.
Quick checks we recommend first
- Confirm you selected Broil (not Bake) and set a broil temperature or Hi/Lo option.
- Make sure the oven door is in the correct broil position (some ranges require the door closed; others allow slightly ajar depending on design).
- Verify the range has gas supply: other surface burners should light and burn steadily.
- Cancel the cycle, wait 60 seconds, then try Broil again to reset the control logic.
- If you smell gas without ignition, stop and ventilate; do not keep retrying.
What to look for during a broil attempt
When you start Broil, watch and listen for a normal ignition sequence.
| What you observe | Most likely cause | What to do next |
|---|---|---|
| No glow from igniter | Failed igniter, wiring issue, or control not sending power | Inspect wiring; test igniter circuit; consider replacing igniter, hot surface W11590294 |
| Igniter glows but no flame after 60 to 90 seconds | Weak igniter (common), gas valve not opening, restricted burner | Replace igniter first; then inspect burner and gas path |
| Flame lights but is small, noisy, or uneven | Clogged burner ports, misalignment, or low gas flow | Clean burner area; check burner seating and air shutter |
| Broil works sometimes | Weak igniter, loose connection, or intermittent control | Check connections; igniter replacement is the most common fix |
Parts that commonly fix a dead broiler on this model
- Igniter, hot surface W11590294 (most common on gas broil systems)
- Oven burner and related hardware (inspect for damage or heavy corrosion)
- Electronic control (if it never sends power to the igniter)
Why it matters
A gas broiler depends on the igniter drawing enough current to open the gas valve. If the igniter is weak, it can glow but still fail to light the broil burner, leading to long preheat times, no broil heat, or intermittent operation.
