Where to find model number on Whirlpool gas range?
On a Whirlpool gas freestanding range like model GS445LEMS4, the model number is usually printed on a rating label around the oven door area. We typically find it on the frame behind the storage drawer, on the oven door frame, or along the lower front edge of the oven opening.
- Open the oven door and look along the left or right door frame (the front frame of the oven cavity).
- Pull out the storage drawer (if your range has one) and check the frame behind the drawer.
- Look along the bottom front lip of the oven opening (near the door hinges).
- Check the back panel of the range near the gas line connection (less common, but possible).
- Turn the oven light on and use a flashlight.
- Open the oven door fully and scan the front frame on both sides.
- If you do not see it, remove the storage drawer and look straight up and along the front frame.
- Write down the full model number exactly as shown (letters and numbers).
| What you may see | What it means | Why you need it |
|---|---|---|
| Model (example: GS445LEMS4) | Your exact range model | Ensures diagrams and parts match |
| Serial number | Unique unit ID | Helps with age and production run |
| Gas type / ratings | Fuel and electrical info | Helps with safe service and setup |
We use the model number to match the correct Whirlpool parts and configurations for your range. Even small model-number differences can change which igniter, gas valve, or door parts fit.
If you are ordering parts for ignition or heating issues, the model number helps us match items like the range broil burner igniter WP8054129 or the range gas valve assembly WPW10293048 correctly.

Why is my Whirlpool gas stove working but not the oven?
If the surface burners work but the oven on your Whirlpool GS445LEMS4 will not heat, the most common causes are a weak oven igniter, a failed oven temperature sensor, or a problem in the gas valve circuit. Start by checking for igniter glow and proper preheat behavior.
- Confirm the oven is set to BAKE (not BROIL) and the temperature is above room temp.
- Listen for a click and watch for the igniter to glow within 30 to 90 seconds.
- If the igniter glows but there is no flame after 60 to 120 seconds, the igniter is typically too weak to open the valve.
- If the oven heats sometimes but is inaccurate, the sensor is a top suspect.
- If you see an error code, use Whirlpool freestanding range error codes to narrow the failure.
| Symptom | Most likely cause | Common next step |
|---|---|---|
| Igniter glows, no flame | Weak igniter | Replace range oven igniter WP8054129 |
| No glow, no flame | Igniter open, wiring issue, control issue | Check wiring connections; test igniter continuity |
| Oven heats but temp is off | Sensor out of range | Test or replace oven sensor WPW10181986 |
| Surface burners OK, oven never lights | Gas valve circuit issue | Professional diagnosis; valve and control checks |
- Power off the range at the breaker before accessing panels or wiring.
- Inspect the igniter for cracks, white spots, or damage.
- Run BAKE and time how long it takes to ignite; long delays point to a weak igniter.
- If you have a multimeter, test the oven sensor resistance at room temperature; a sensor that reads far off typical range values often causes no-heat or poor temperature control.
- If the igniter and sensor check out, the issue can be wiring, the control, or the gas valve circuit.
The oven burner needs the igniter to draw enough current to open the gas valve reliably. Surface burners use a different ignition and gas path, so they can work normally even when the oven ignition system is failing.

What is the average lifespan of GS445LEMS4?
A Whirlpool gas freestanding range like the GS445LEMS4 typically lasts 15 years with normal household use and basic maintenance. Keeping burners clean, ensuring proper ignition, and replacing wear parts when symptoms appear helps you reach that expected service life.
- Heat and grease buildup on the cooktop and in the oven cavity
- Ignition system wear (spark module, igniters, switches)
- Oven temperature accuracy (sensor performance)
- Door sealing (gasket condition affects heat retention)
- Usage patterns (high-heat broiling and frequent baking add wear)
If performance drops but the range is otherwise in good shape, these model-compatible parts are often involved:
| Symptom | Likely part | Example from this model’s parts |
|---|---|---|
| Oven not heating or slow to ignite | Oven igniter | Range oven igniter WP8054129 |
| Oven temperature swings, bakes unevenly | Oven sensor | Oven sensor WPW10181986 |
| Clicking or weak sparking at surface burners | Spark module | Spark module WPW10331686 |
| Heat leaking, longer preheat times | Door gasket | Door gasket W11542153 |
- Clean burner heads and caps regularly; keep ports clear
- Wipe spills promptly to prevent corrosion and stuck valves
- Avoid lining the oven bottom with foil (it can trap heat and damage components)
- Check that the range sits level; adjust feet if needed
- Replace failing ignition parts early to prevent repeated no-heat events
A range’s “lifespan” is usually limited by a few high-heat, high-use components (igniters, sensors, door seals). Replacing those targeted parts is often more cost-effective than replacing the entire Whirlpool GS445LEMS4.
