Heil Quaker ICP 1172533 Ignitor

When you are out on a service call and finding an open circuit on a Heil Quaker ICP 1172533 Ignitor, you need a direct OEM replacement that matches the original furnace sequence of operation. This 120V Hot Surface Ignitor (HSI) is a critical component for ensuring reliable burner ignition in 80% and 90% AFUE gas furnaces. Engineered for high-temperature resistance, this Silicon Nitride ignitor replaces older, more fragile silicon carbide versions, offering superior durability against the rapid thermal expansion cycles common in residential heating applications.

This ICP 1172533 assembly features the correct 2-prong terminal plug for a seamless "plug-and-play" installation, eliminating the need for field splicing with ceramic wire nuts in most International Comfort Products (ICP) units. Whether you are working on a Heil, Tempstar, Comfortmaker, or Arcoaire furnace, verifying compatibility with the LH33ZG002 or SSN2533 cross-reference numbers ensures the control board sees the correct resistance for the ignition strike. As a veteran tech knows, even a hairline crack or skin oil contamination on the element will lead to a premature failure; handle this part by the ceramic base only to safeguard system uptime.

Key Benefits for the Contractor:

• Direct OEM Compatibility: Verified fit for a wide range of Heil Quaker and ICP furnace models, including C8DNL, C9MPD, and C9MPV series.
• Upgraded Material: Transitioning to Silicon Nitride provides a more robust ignition strike and higher resistance to physical impact compared to legacy carbide ignitors.
• Precision Timing: Optimized for standard 120V ignition modules, maintaining the precise 17-to-34 second warm-up window required by the inducer motor and gas valve sequence.
• Reduced Service Callbacks: High-purity materials prevent the "hot spot" failures often seen with low-quality aftermarket universal ignitors.

Common Questions & Troubleshooting:

• What is the typical resistance for an ICP 1172533? At room temperature, you should be looking for a continuity reading between 40 and 100 ohms depending on the specific element version; an infinite or "open" reading always indicates a failed part.
• Why did the original ignitor fail prematurely? Beyond standard wear, check for high gas pressure or a malfunctioning control board that is leaving the hot surface ignitor energized too long after the flame sensor has proven the pilot.
• Can I replace a carbide 1172533 with this nitride version? Yes, this is the recommended technical upgrade. Ensure the mounting bracket aligns perfectly so the element is properly immersed in the gas flow for a clean light-off.
