Upgraded Replacement 0130F00010 Fits Goodman Furnace Flame Sensor

The Popbee 0130F00010 replacement is designed for broad compatibility with models like B11726-06 and 0130F00010 across brands such as Kenmore, Amana, and Goodman. It reliably detects flame presence to prevent unsafe ignition cycles. Best for homeowners with multiple older or varied furnace models who want a single replacement option.
Best for: Homes with Goodman, Kenmore, or Amana units needing a straightforward flame sensor swap. Better for: users seeking a cost-effective 3-pack solution that reduces replacement frequency. Choose this if: you want a widely compatible sensor that’s easy to source. Caution: verify model numbers before purchasing to ensure exact fit.
69L17 J4117 Pilot Assembly with Flame Sensor – BeHonor

The 69L17 pilot assembly includes ignition components and is designed for natural gas direct-vent fireplaces from brands like Lennox, Ihp, Serefina, Superior, and Merit. It helps address ignition failure, no heat, or unstable heating by replacing the entire pilot assembly rather than a single sensor. Best for: units with SIT valves requiring a bundled pilot upgrade. Better for: users replacing aging pilot hardware; choose this if you need integrated ignition components. Caution: only compatible with natural gas units that use SIT valves and separate pilot groups.
OEM Upgraded Rheem Furnace Flame Sensor – Seneca River Trading

The Seneca River Trading replacement targets Rheem furnace flame sensors, offering a direct part replacement for models that use the 62-23543-01 series. Best for: Rheem-direct vent or similar configurations needing an authentic sensor replacement. Better for: ensuring proper flame detection with minimal compatibility concerns. Caution: verify your specific Rheem model number to confirm exact fit.
24″ 750 Millivolt Thermopile Generator – PuBaDuoParts

This 24″ thermopile serves as a self-contained power source for standing pilot systems in fireplaces, water heaters, and gas ovens where external electricity is unavailable. It’s ideal for off-grid setups or during power outages. Best for: appliances needing ignition power without wiring. Better for: long-term reliability in remote or backup operation. Caution: intended for standing pilot configurations; verify your system’s ignition method.
M8 Thermocouple 600mm – East buy

The East buy M8 Thermocouple offers a standard 8×1 thread with a 600mm probe, built for high-temperature resistance up to 850°C (1562°F). It provides precise flame sensing for gas fireplaces, grills, water heaters, and similar appliances. Best for: general replacement needs with a long, robust probe. Better for: spaces where a longer sensor helps reach the flame precisely. Caution: ensure correct thread size and length for your unit.
Propane Gas Fire Pit Flame Failure Safety Valve Kit – WADEO

The WADEO safety valve kit is designed for propane fire pits, grills, and fireplaces requiring a robust flame failure safety control. It includes a thermocouple and valve components suited for low-pressure systems. Best for: outdoor gas pits and grills where safety shutoff is critical. Better for: upgrading to a dedicated safety valve in existing low-pressure piping. Caution: verify compatibility with your specific outdoor appliance’s valve diameter and connection type.
Buying Guide
What should I consider when choosing a flame sensor or related ignition part?
Compatibility with your appliance brand and model is essential. Check part numbers and valve types (SIT valves, standing pilot, etc.).
Sensor type matters: flame sensors, thermopiles, and thermocouples serve different roles. Ensure you select the correct type for your ignition system.
Is a replacement sensor enough, or should I replace the entire pilot assembly?
If ignition failures persist after sensor replacement, a full pilot assembly may be more reliable. This can address misaligned burners, ignition timing, or valve operation in one step.
Can I install these parts myself, or should I hire a pro?
Many replacements are straightforward, but gas systems pose safety risks. If you’re unsure about wiring, valves, or gas leaks, hire a licensed technician.
What about off-grid or power-out scenarios?
Thermopile generators provide ignition power without external electricity, ideal for areas with frequent outages or remote installations.
Safety and installation tips
- Turn off gas supply and power before any replacement.
- Inspect for gas leaks after installation with approved detectors.
- Follow manufacturer instructions precisely for torque and wiring.
FAQ
- What is a flame sensor used for in gas fireplaces?
A flame sensor detects flame presence to allow gas valve operation and prevent unburned gas from flowing if ignition fails.
- Will a new thermocouple fix a flame-out problem?
It can fix intermittent flame outage if the thermocouple is degraded or misreading flame temperature.
- Do I need to replace the entire pilot assembly or just the sensor?
Replace the sensor if the ignition components are still functioning; replace the entire pilot assembly if ignition or flame stability remains a problem.
- Are these parts compatible with all gas fireplaces?
Compatibility depends on model, valve type, and gas type. Verify part numbers and model references before buying.
- Can I retrofit a standing pilot system with a thermopile generator?
Yes, for systems relying on standing pilots, a thermopile generator can provide ignition power without external electricity.
- What risks are involved with DIY gas sensor replacement?
Improper installation can lead to gas leaks or fire hazards. Always follow safety protocols and local codes, or consult a professional.
