7006U Cad Cell Flame Sensor Kit for Beckett Oil Burners
The 7006U Cad Cell Flame Sensor Kit is a direct replacement designed for Beckett 7006U, 7135U, and Honeywell C554A1687 parts. It is fully compatible with Beckett A, AF, AFG, NX, SR, SF, and RW burners, restoring original installation positioning. Best for homeowners performing DIY maintenance or emergency replacements when a direct fit is required. Working temp range from -40°F to 140°F supports typical boiler room conditions. A potential limitation is the need to confirm exact burner model alignment before purchase to avoid misfit.
Who this is best for: Homeowners seeking a straightforward swap with minimal downtime; technicians needing reliable parts that mirror original configurations; property managers prioritizing compatibility across common Beckett burners.
7006U Cad Cell Flame Sensor Kit, Extended 31.1″ Wire Lead
This upgraded kit adds a longer 31.1″ wire lead, maintaining compatibility with Beckett A, AF, AFG, NX, SR, SF, and RW burners. It serves as a direct replacement for 7006U, 7135U, and C554A1687 and keeps the original installation footprint. The high-temp cad cell eye remains capable of withstanding typical combustion chamber environments (-40°F to 140°F). It is especially suitable for installations where wiring length is a constraint or where components must reach a distant control panel. Limitation: longer wires may require additional routing considerations to avoid heat exposure or physical wear.
Who this is best for: Installers needing extra wire length; homeowners upgrading a burner with distant controls; service teams prioritizing flexible wiring during replacement tasks.
Replacement Oil Burner Cad Cell Eye Fits Honeywell 120320/124607/130367
This replacement targets Honeywell/C554A1687 family parts, matching multiple part numbers including 120320, 124607, and 130367. It is built to fit oil burner cad cell eye replacements across several brands, including Restwood E81 and Carlin configurations. Best for service providers who need broad compatibility and straightforward cross-reference guidance. A potential limitation is that exact model cross-compatibility should be verified to ensure wiring and connector alignment with your specific control box.
Who this is best for: Technicians performing cross-brand replacements; homeowners with Honeywell-based systems seeking a direct cad cell eye swap; maintenance teams needing a versatile fit for older equipment.
Oil Burner Cad Cell Eye Parts Compatible With Beckett/Carlin/Wayne
These cad cell eye parts are designed for Beckett, Carlin, and Wayne oil burners, with cross-compatibility for several standard cad cell part numbers (120320, 124607, 130367). They offer a broad-fit option for mixed-use maintenance on multi-brand systems. Best for contractors or homeowners with diverse burner inventories. Limitation: Some installations may require adjustments to wiring or seals to ensure a proper seal and function with non-Beckett burners.
Cad Cell Flame Sensor Kit With 30″ Wire Lead Set
This kit is designed for Beckett A, AF, AFG, NX, SR, and SF burners, using a 30″ wiring harness for flexible installation. It replaces original numbers 120320, 124607, 130367, and C554A1687, providing a consolidated solution for multiple part families. Best for upgrades in complex burner rooms where wiring harness routing benefits from a longer lead. Limitation: Some users may need to trim or manage extra length to avoid snagging or damage to exposed wiring.
Buying Guide: Key Considerations For Flame Sensor Replacements
Compatibility first: Confirm your burner brand and model (Beckett, Honeywell, Carlin, Wayne) and compare the listed part numbers. A direct replacement that mirrors the original part ensures the closest fit and easiest wiring alignment.
Lead length and harness: Longer wire leads offer installation flexibility but require careful routing to avoid heat exposure, abrasion, or contact with moving parts. Match lead length to your burner layout.
Temperature tolerance: Flame sensors operate in high-temperature environments. Choose sensors rated to survive typical boiler-room conditions and repetitive heat cycling to maintain long-term reliability.
Installation effort: Some kits advertise “DIY friendly” installation. While many swaps are straightforward, always disconnect power and follow wiring diagrams. Larger kits with multiple components may require more careful alignment with existing control boards.
Cross-compatibility: If you have multiple brands in one facility, consider a kit that covers several part numbers or burner models to simplify future replacements and inventory management.
Quality and materials: Look for cad cell eyes with robust heat-resistant construction and solid wire insulation. Durable components reduce false flame detections and misfires, improving safety and performance.
FAQ
- What is a flame sensor in an oil burner? It is a safety device that detects whether a flame is present after ignition and helps control the burner’s operation to prevent unburned fuel accumulation.
- Will these parts fit any Beckett burner? Most listed items fit common Beckett A, AF, AFG, NX, SR, SF, and RW series, but always verify the exact model and part numbers before purchase.
- Can I install these parts myself? Many are marketed as DIY-friendly, but ensure you have power disconnected and follow wiring diagrams to avoid electrical hazards.
- What happens if I use the wrong cad cell eye? An incompatible sensor may fail to detect flame correctly, causing misfires or burner shutdowns. Always confirm model compatibility.
- Do longer wire leads affect performance? Longer leads offer routing flexibility but require careful management to avoid wear, heat exposure, or interference with burner components.
- Are these sensors compatible with multiple brands? Some parts are cross-compatible with Honeywell, Beckett, Restwood, Carlin, and OC-10 families, but verify part numbers and wiring connectors for your specific system.
