Upgraded Replacement 0130F00010 Flame Sensor For Goodman
Brand: Popbee
Key features: High compatibility with B1172606 0130F00010 and numerous model variants; supports brands such as Kenmore, Amana, and Goodman for smooth operation. The sensor has undergone testing to detect flames safely, reducing issues like frequent shutdowns and immediate flameouts after ignition. This makes it a reliable choice for homeowners seeking a straightforward, direct replacement for failing flame sensors.
Best for: Homeowners with Goodman, Kenmore, Amana, or similar systems needing a direct flame-sensor replacement. Why selected: It covers a broad set of compatible models and emphasizes safe flame detection to maintain a steady ignition sequence.
Caution: Confirm exact model compatibility before purchasing to avoid mismatched sensor interfaces.
METER STAR Universal Thermocouple 24 Inches
Brand: Earth Star
Key features: Universal thermocouple length of 24″ with M8x1 threaded head; designed to connect to valves and provide consistent flame sensing. The product notes emphasize that the tip location may need adjustment if the system stops working. These details imply a straightforward fix for ignition reliability in many gas fire or grill setups.
Best for: Users seeking a flexible, long thermocouple replacement that can service multiple appliances, including grills and fireplaces. Why selected: Its universal length and threading support quick adaptation to various units.
Caution: Proper tip positioning is essential for reliable sensing; misplacement can lead to ignition issues or unsafe operation.
OEM Rheem Flame Sensor Replacement
Brand: Seneca River Trading
Key features: Replacement part 62-23543-01 branded for Rheem appliances. The product line focuses on a direct compatibility replacement to restore flame sensing in Rheem systems.
Best for: Rheem users needing an authentic replacement sensor. Why selected: It targets a known manufacturer’s sensor family, reducing compatibility concerns.
Caution: Verify the exact Rheem model and sensor part number to avoid mismatches with non-Rheem units.
Heatilator NG Pilot Assembly
Brand: palart
Key features: Replacement part numbers 25660 and 4021-732 for natural gas standing-pilot units. Indicates applicability to NG systems that require a consistent ignition pilot assembly, not compatible with SIT valves. This can be a practical alternative when flame sensor-related ignition issues stem from the pilot assembly itself rather than the sensor.
Best for: Off-grid or stand-alone NG fireplaces and stoves using standing pilots where the pilot assembly, not the sensor, is the ignition bottleneck. Why selected: Highlights a different ignition subsystem that can affect flame detection and reliability indirectly.
Caution: Not compatible with SIT valve systems; confirm valve type before purchase.
24″ Thermopile Generator For Safe Ignition
Brand: PuBaDuoParts
Key features: 750 millivolts thermopile generator with 24″ length; designed to power standing pilot systems in fireplaces, water heaters, and gas ovens without external electrical power. The product emphasizes high-temperature resistance and durable wiring materials for long-lasting ignition reliability.
Best for: Off-grid or power-outage scenarios where a standing pilot must remain operational. Why selected: Provides a self-sufficient ignition power source, reducing dependence on electrical supply.
Caution: Check compatibility with standing-pilot systems and ensure the thermopile voltage output matches your appliance requirements.
M8 Thread 24″ Thermocouple For Fireplaces
Brand: East buy
Key features: M8 thread with 600mm (24-inch) probe, high-grade alloy for up to 850°C; low internal resistance ensures precise flame sensing. Direct replacement for gas fireplaces, fire pits, patio heaters, grills, and water heaters; compatible with various brands such as Gozney, Atosa, and CookRite.
Best for: Professionals or DIYers replacing flame sensors across multiple appliances that use M8-thread thermocouples. Why selected: Combines high-temperature resilience with broad compatibility for easy cross-application.
Caution: This is a replacement thermocouple, not an original sensor; ensure the exact replacement type for your model before purchasing.
Buying Guide: Key Considerations For Gas Fireplace Flame Sensors
What should you check before buying a flame sensor replacement?
- Compatibility: Verify model numbers and brand compatibility. A sensor that fits one unit may not work with another due to electrical connections or valve interfaces.
- Sensor Type: Flame sensors come in several forms (thermocouples, ionization sensors, etc.). Choose the correct type for your system to ensure safe ignition and shutoff
- Ignition System Context: If ignition fails, determine whether the pilot assembly, thermocouple, or the flame sensor is the root cause. Some issues stem from the pilot or thermopile rather than the sensor itself.
- Installation Complexity: Some replacements are plug-and-play; others require wiring or system calibration. Consider professional installation if unsure.
- Safety Standards: Use parts designed for your fuel type (natural gas vs propane) and ensure adherence to local safety codes.
FAQs
- What is the primary purpose of a flame sensor in a gas fireplace? It detects whether the flame is present and signals the control valve to stay open or shut off for safety.
- Can I replace a flame sensor myself? Yes, many direct-swap sensors are designed for consumer installation, but some models require professional assistance.
- How do I know if the sensor is the problem? Symptoms include frequent shutdowns, no ignition, or flameout after ignition. A replacement part specific to your model is often needed.
- Is a thermocouple interchangeable with a flame sensor? Not always. Thermocouples generate a millivolt signal that certain controls use to verify flame presence, while other sensors may use different sensing methods.
- What safety checks should I perform after replacement? Test ignition cycles, confirm the flame remains steady, and ensure there is no gas odor during operation.
- Do replacement parts affect warranty coverage? Replacement parts may affect warranties; check the appliance’s warranty terms before replacing components.
