Where to find model number on Whirlpool gas range?
On the Whirlpool WFG775H0HZ0 gas range, we find the model number on the model/serial rating plate located on the oven frame behind the top right side of the oven door. Open the oven door and look along the frame near the upper-right area for the label.
Quick steps to locate the rating plate
- Turn the oven light on if needed for visibility.
- Open the oven door fully.
- Look on the oven frame (not the door) near the top right side.
- Find the model/serial rating plate and read the model number and serial number.
- Write the model number exactly as shown (letters and numbers).
What the label looks like and what it includes
The rating plate typically lists key identification and fuel information.
| Item on label | What it’s used for |
|---|---|
| Model number | Matching the correct Whirlpool parts and diagrams |
| Serial number | Identifying production details for service and support |
| Gas type info | Confirming Natural gas vs. Propane conversion requirements |
Why it matters
We use the model number to ensure you get the right parts for your exact range configuration (controls, igniters, door parts, and more). It also helps confirm gas type details before any conversion or service work.
Helpful tip when ordering parts
If you’re troubleshooting an oven heating issue, having the model number ready helps us match common heating-related parts, such as the range oven igniter WPW10324262 or the range oven temperature sensor WPW10181986, to your exact Whirlpool range.
For the official location details, use the WFG775H0HZ0 owner’s manual.

What size gas line for Whirlpool gas range?
For the Whirlpool WFG775H0HZ0 gas range, we recommend a 3/4-inch rigid gas supply pipe to the range location; for propane (LP), 1/2-inch minimum piping or tubing is typically acceptable. Using undersized pipe on long runs can cause low gas flow and poor burner performance.
Recommended gas line sizes (what to use)
- Natural gas: 3/4-inch (19 mm) rigid pipe to the range location
- Propane (LP): 1/2-inch (13 mm) minimum piping or tubing (your LP supplier often specifies final sizing)
- Flexible connector (if allowed by local code): 1/2-inch or 3/4-inch I.D., typically 4 to 5 ft long
- Shut-off valve: install a manual shut-off valve in an easy-to-reach location
- Threading note: the range regulator connection typically uses 1/2-inch male pipe thread
For the exact installation requirements and approved connection methods for this model, follow the WFG775H0HZ0 installation guide.
Quick sizing guide (common situations)
| Situation | Typical best practice | What can go wrong if too small |
|---|---|---|
| Short run from meter to range (natural gas) | 3/4-inch rigid pipe | Weak flames, slow preheat, burner dropouts |
| Longer run with multiple gas appliances | 3/4-inch (or larger per sizing tables) | Pressure drop under load |
| Propane system | 1/2-inch minimum (supplier may upsize) | Poor ignition, uneven flames |
Why it matters
Correct gas line sizing helps the oven burner and surface burners get steady fuel flow. When the line is too small, pressure drop increases, which can lead to inconsistent heating, longer cook times, and ignition problems.

Why is my Whirlpool cooktop igniter not working?
On the Whirlpool WFG775H0HZ0 gas range, a cooktop igniter usually stops working because the range has no power, the gas supply is off, the burner cap is mis-seated, or the igniter area is dirty or wet. Start with power and cap alignment checks, then move to ignition parts.
Quick checks (most common fixes)
- Confirm the range is plugged in and the circuit breaker is on.
- Verify the gas shut-off valve is fully open.
- Reseat the burner cap so it sits flat on the burner base and aligns with the pins.
- Dry the igniter area if it got wet during cleaning.
- Clean burner ports and the cap; keep spills out of the gas tube opening.
- Turn the knob to LITE/IGNITE and listen: all burners may click, but only the selected burner should light.
What the clicking and symptoms usually mean
| Symptom | Most likely cause | What to do next |
|---|---|---|
| No clicking on any burner | No power to range, failed spark module | Check power first; then consider spark module (red) WPW10475149 |
| Clicking but no flame | Gas off, air in line, cap not seated, clogged ports | Open gas valve; reseat cap; clean ports |
| One burner won’t spark but others do | Dirty/wet igniter, bad electrode, bad burner base | Clean and dry; inspect and consider electrode WPW10515459 or cooktop burner base WPW10333445 |
| Sparks but lights slowly or unevenly | Dirty ports/cap, cap misalignment | Clean and reseat cap |
When a part is likely needed
If power and gas are good and the cap is correctly positioned, ignition failures often point to a failed electrode or spark module.
- Replace the electrode when only one burner has no spark.
- Replace the spark module when none of the burners spark.
Why it matters
A properly seated burner cap and clean burner ports help the electronic ignition system light within a few seconds and keep flames stable and blue. Misalignment or debris can prevent ignition and cause delayed lighting.
