Heil Quaker ICP 1183890 Conversion Kit

The Heil Quaker ICP 1183890 Conversion Kit is a critical field upgrade designed to transition older gas furnaces from a legacy radiant sensor configuration to a modern, more reliable flame sensor system. This kit is essential for service technicians working on older Heil, Quaker, and International Comfort Products (ICP) units where the original radiant sensors have failed or become obsolete. By converting to a rectified flame sense signal, you ensure more consistent burner monitoring and reduce nuisance lockouts caused by thermal lag or sensor fatigue. The 1183890 kit includes the necessary hardware to modify the burner assembly, providing a stable microamp signal back to the integrated furnace control board. This HVAC replacement part is engineered for high-heat environments, ensuring long-term continuity in the ignition sequence. Precise alignment during installation is required to ensure the probe remains in the flame envelope for proper furnace ignition system performance and safety circuit verification.

Key Benefits

• Enhanced Reliability: Replaces outdated radiant technology with modern rectification for more stable flame detection.
• Direct Compatibility: Engineered specifically for Heil Quaker and ICP gas furnaces to ensure proper fitment.
• Reduced Maintenance: Minimizes intermittent ignition failures and service call-backs associated with aging sensor technology.
• Complete Retrofit: Provides the necessary components to update the ignition system without replacing the entire furnace.

Common Questions

Why should I use the 1183890 kit instead of a standard sensor?
Older units utilize a radiant sensor that detects heat rather than electrical rectification. This kit allows you to upgrade the system to use a standard flame probe, which is the current industry standard for reliability.

Does this kit require a specific control board?
Yes, this conversion is typically part of a larger upgrade or must be paired with a control board capable of interpreting a flame rectification signal rather than a simple switch closure.

What are the signs of a failing radiant sensor?
Common indicators include the burner extinguishing immediately after the trial for ignition or the sensor failing to "prove" the flame despite a visible burner light-off.
