Laars Heating Systems RW2002300 Hot Surface Ignitor
The Laars RW2002300 Hot Surface Ignitor is a critical OEM 120V ignition component designed for high-input hydronic boilers and volume water heaters. This hot surface ignitor with gasket is the factory-authorized replacement for the legacy W0038001 part number. Engineered with a 24-inch lead for versatile routing, it provides the 120V HSI ignition required for the 20-second pre-purge cycles standard in Laars Pennant (PNCH/PNCV) and MightyTherm2 series units. The included high-temperature mounting gasket ensures a gas-tight seal on the burner tray, preventing combustion air bypass and maintaining established flue gas CO2 levels.
For technicians servicing Laars Heating Systems, this ignitor is compatible with a wide range of commercial models, including the Pennant 500-2000 MBH series and MightyTherm 200-400 units. Its silicon carbide construction is designed to withstand the rapid thermal expansion cycles typical of multi-stage firing systems. When troubleshooting an ignition lockout code on the Laars Linc or RE0253400 ignition controller, verifying the resistance of this part—typically between 40 and 100 ohms—is the standard diagnostic step before replacing the boiler ignitor assembly to restore reliable burner sequencing.
-
Key Benefits
- Direct OEM Replacement: Seamlessly replaces legacy part W0038001 without modifications to the burner pilot bracket.
- Precise Fitment: Comes with a pre-cut high-temperature gasket to ensure a verified seal during HVAC preventative maintenance.
- Robust Compatibility: Designed for Laars Pennant PNCH and PNCV models, ensuring exact electrical match for 24V control/120V ignition circuits.
- Enhanced Durability: Thermal-shock resistant element prevents premature failure during high-demand heating cycles.
Common Questions
Is the RW2002300 compatible with my Pennant boiler?
Yes, the RW2002300 is the primary replacement ignitor for Laars Pennant models ranging from 500,000 to 2,000,000 BTU, as well as several MightyTherm and Rheos configurations. It replaces the old W0038001 number exactly.
Can I touch the ignitor element during installation?
No. As a veteran tech knows, skin oils can cause localized hotspots and lead to premature element failure. Always handle this replacement ignitor by the ceramic base and use clean gloves.
What are the symptoms of a failing Laars hot surface ignitor?
Common indicators include the system cycling through pre-purge but failing to establish flame, visible hairline cracks on the element, or a resistance reading outside of the 40-100 ohm operational range.
