Whirlpool Gas Range Oven Not Heating or Burner Flame Weak? Pressure Regulator W11449506 – Fix Gas Flow Fast
A gas range oven that won't heat properly, has a weak or uneven burner flame, or shuts off mid-cycle almost always has a failed gas pressure regulator. In most Whirlpool and Maytag gas ranges, the pressure regulator controls and stabilizes the gas pressure delivered to the oven burner and surface burners. When it fails or drifts out of spec, gas pressure drops below the level needed for proper combustion — the oven flame is weak, uneven, or won't sustain, and the oven can't reach or hold temperature. ⚡ Common failure point in Whirlpool-built gas ranges. Part W11449506 is the genuine OEM replacement that restores correct regulated gas pressure and full burner performance immediately.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Gas supply to the range is confirmed on and at normal household pressure
- ✔ Oven igniter glows and ignites (rules out igniter failure)
- ✔ Gas supply line and shut-off valve confirmed fully open and unobstructed
- ✔ ONLY problem is weak oven flame, oven not reaching temperature, uneven heating, or burner flame that won't sustain at normal height

🔧 Common Symptoms
- Oven burner flame is weak, low, or uneven across the burner
- Oven takes excessively long to preheat or never reaches set temperature
- Oven flame shuts off mid-cycle and won't re-ignite at full height
- Surface burners also affected — low flame on all burners simultaneously
- Gas smell without full ignition (insufficient pressure to sustain combustion)
✔ If these symptoms match, this is the most likely failed component in the system.
✔ In most cases, replacing this pressure regulator restores full gas pressure and normal burner performance immediately.
📦 Part Details
- Part Number: W11449506
- Type: Gas Range Pressure Regulator
- Brands: Whirlpool, Maytag, KitchenAid, Amana
- OEM: Genuine Whirlpool replacement part
While the range is pulled out for access, inspect the gas supply line and shut-off valve behind the range. A partially closed or corroded shut-off valve causes identical low-pressure symptoms and is often overlooked. Confirm the valve is fully open and the supply line is not kinked or restricted before completing the repair.
⚙️ Installation
Skill Level: Advanced — 45–60 minutes. Gas work requires care. Shut off the gas supply at the wall valve before servicing. Disconnect power at the breaker. Pull the range away from the wall, locate the pressure regulator in the gas supply path (typically at the manifold or inlet), disconnect the gas fittings using appropriate wrenches, install the new regulator with fresh thread sealant on all fittings, and reconnect. Restore gas supply and check all connections for leaks with soapy water before restoring power and testing. If you are not comfortable working with gas lines, contact a licensed technician.
✓ Compatible Models
Confirmed compatible with select Whirlpool, Maytag, KitchenAid, and Amana gas range models. Contact us to verify your model number before ordering.
💡 Pro Tip
After installing the new regulator and restoring gas supply, check every fitting you touched with a soapy water solution — bubbles indicate a leak. Do not use an open flame to check for leaks. A properly tightened fitting with thread sealant should show no bubbling within 30 seconds. If you detect a leak, shut off the gas immediately and re-tighten or reseal the fitting before proceeding.
