Water Heater Igniter 9003410 C3 Piezo Ignitor Assembly
This assembly is marketed as a direct replacement for part number 9003410 and SP14410, fitting Reliance FVIR-technology gas water heaters and many later-model Rheem, Whirlpool, A.O. Smith, and Bradford White units. The product emphasizes high-quality materials for durability, and lists the ignitor and bracket as an important component to restore normal heating when a water heater fails to ignite or heat properly.
Use this igniter assembly when your water heater shows symptoms such as failure to ignite, inconsistent heating, or when OEM part cross-reference matches 9003410. Ensure compatibility by confirming your heater model and examining existing mounting/bracket orientation before installation.
Reliance Water Heater Co 9003410 C3 Piezo Ignitor Assembly
This listing is a specific OEM-designated ignitor for gas water heaters and is presented as the original equipment replacement. The main feature listed is its specification for gas water heaters, implying straightforward swap-in compatibility for systems requiring a 9003410-style assembly.

Choose this product if your service manual or existing part label matches the 9003410 designation and you prefer a like-for-like replacement. Confirm mounting holes, wire connections, and physical dimensions against your removed unit to avoid fitment issues.
Upgraded SP20075 Pilot And Igniter Assembly Compatible With Rheem
This upgraded SP20075 pilot and igniter assembly is intended for Rheem and similar natural gas water heaters. The listing highlights common pilot light issues it addresses: slow ignition, intermittent pilot, thermocouple heating failures, and leaks at water inlet gaskets. Materials are described as tested for durability and the gaskets use silicone to resist high temperatures.
Compatibility notes reference specific Rheem model families and common replacement needs. Inspect the current pilot assembly appearance before purchase and match part connections. This combined pilot-and-igniter format can simplify replacement for systems that use an integrated pilot assembly.
Lrichy 93868 Igniter Electrode For RV Water Heater
The Lrichy 93868 electrode is designed as a replacement spark probe and sensor electrode for Atwood and compatible RV water heaters, including multiple GH, GC, GCH, and XT series models. The product emphasizes wide model compatibility and ease of installation as it matches Atwood model 93868 form factor.

Guidance points include verifying the electrode gap and alignment with gas flow; correct gap and clean probes are essential for consistent sparking. This spare part is targeted at RV owners and technicians replacing worn spark probes or sensor electrodes in 6- and 10-gallon RV storage water heaters.
Gosknor 2pcs Piezo Spark Igniter Replacement Kit
The Gosknor kit includes two piezo spark igniters, two wires, and two screws for installation. Listed dimensions include an igniter length of 8.7 cm and wire length of approximately 96 cm with an overall effective length of 5 cm stated for part of the assembly. Construction uses ceramic and metal for durability.
This kit targets grills, gas fireplaces, ovens, and generic heaters that use push-button piezo ignition electrodes. The inclusion of wires and screws can simplify small repairs. Verify electrode thread size and mounting depth before replacing to ensure the thread and ceramic body fit your appliance’s igniter bracket.
Buying Guide: How To Choose The Right Heater Igniter
Selecting the right igniter requires attention to compatibility, ignition method, and installation constraints. Below are primary considerations to evaluate multiple replacement options objectively.
Heater Type And Application
- Gas Water Heaters: Look for OEM numbers (e.g., 9003410) or compatible assemblies listed for your brand (Reliance, Rheem, A.O. Smith).
- RV Water Heaters: Spark probe/electrode models (e.g., 93868) are common; check model lists for GH/GC/XT series compatibility.
- Grills/Fireplaces/Ovens: Piezo push-button igniters and threaded electrode replacements often work across models; confirm thread and mounting length.
- Pool/Pool-Spa Heaters: These use manufacturer-specific igniters; verify part numbers and model series (e.g., Pentair/Sta-Rite lists).
Part Numbers And Cross-Reference
- Confirm the OEM part number on your existing component or service manual. Cross-reference numbers like 9003410 or model-specific IDs to avoid fitment issues.
- When an exact OEM is unavailable, select parts explicitly listed as compatible with your heater models and series.
Ignition Type And Electrical Requirements
- Piezo Igniters: Mechanical spark generation (no battery/electric wiring) — common for grills and some pilot assemblies.
- Electrode/Sensor Probes: May require connection to control modules; ensure wire length and connector type match.
- Pilot And Igniter Assemblies: Integrated units combine thermocouple/pilot and ignition; useful when multiple components are aged.
Physical Fitment And Mounting
- Check thread type, ceramic body length, wire length, and bracket mounting. Short wires or incompatible threads are common failure points during replacement.
- For RV and compact heaters, probe position and gap are critical. Maintain recommended spark gap (often about 1/8 inch) and ensure probes are clean.
Material Durability And Heat Resistance
- Ceramic insulators and heat-resistant metals extend service life in high-temperature burners and pool heater environments.
- Silicone gaskets in pilot assemblies resist high temps and minimize leaks for long-term sealing performance.
Installation And Safety Considerations
- Turn off gas and power before replacing igniters. Follow manufacturer instructions or professional guidance.
- Confirm seals, gaskets, and thermocouple condition when replacing igniters to avoid persistent failures due to other degraded components.
- Observe local codes and safety practices when servicing gas appliances.
Compatibility Perspectives And Troubleshooting
- Symptom-Based Replacement: If the heater fails to ignite, sparks are weak, or ignition is intermittent, the igniter or probe is a likely candidate. Also inspect wiring and control boards.
- Comprehensive Swap: For aging systems with multiple worn parts, replacing a combined pilot-and-igniter assembly can address pilot, thermocouple, and ignition faults together.
- Model-Specific Approach: For brand-specific units (Rheem, Reliance, Atwood, Pentair), prioritize parts listed as compatible or OEM to ensure correct fit and performance.
Comparing Options
- OEM Replacements: Often provide the best fit and interchangeability but verify you have the correct part number.
- Aftermarket Kits: Useful when OEM is unavailable; check reviews for fit and durability and verify included hardware (wires/screws/gaskets).
- Integrated Assemblies: Simplify repair when multiple components are suspected of failing; ensure overall assembly layout matches your unit.
Use the above checklist to cross-match part numbers, mounting styles, and ignition types. Proper identification of the failed component and matching it to the listed compatibility information reduces rework and ensures reliable heater ignition after replacement.
