Carrier LH33WP001 Ignition Module

The Carrier LH33WP001 is a professional-grade Direct Spark Ignition (DSI) Module engineered for high-demand HVAC applications. This factory authorized part is the primary control component for managing the ignition sequence in gas-fired furnaces and rooftop units, ensuring precise flame rectification and system safety. As a veteran-preferred OEM replacement ignition control, it is identical to and replaces the G765BAD-1 and G765BAD-1R models. The module operates on a 24 VAC nominal control circuit and features a high-voltage capacitive discharge spark source for reliable burner lighting. With a 3-trial ignition sequence and a 0.8-second flame failure response time, this DSI ignition control provides the robust timing and safety logic required by modern commercial and residential Carrier HVAC systems. Its remote sensing capabilities and 0.5 microampere minimum flame current threshold ensure stable operation under varied gas pressures and ambient conditions, making it an essential furnace ignition module for maintaining peak equipment performance.

• Universal Compatibility: Directly replaces legacy G765BAD-1 and G765BAD-1R modules without requiring bracket modifications.
• Precision Safety Logic: Features a 5-minute automatic recycle delay and a 30-second interpurge for maximum safety during direct spark ignition cycles.
• Durable Construction: Built to withstand commercial environments with an operating temperature range of -40°F to 175°F.
• Simplified Diagnosis: Compatible with standard 1/4-inch male spade connectors for fast field testing and secure electrical termination.
• Reliable Flame Sensing: Utilizes advanced flame rectification technology to prevent nuisance lockouts and ensure a steady call for heat.

• What fits the LH33WP001? It is primarily designed for Carrier, Bryant, and Payne 48DJD series units and replaces the 1016-572 series modules.
• How do I reset a lockout? If the module enters safety lockout after failing three ignition trials, cycle the 24V power at the thermostat or main disconnect for 30 seconds to initiate a manual reset.
• Can I use this for intermittent pilot systems? No, the LH33WP001 is a dedicated DSI module and is not a substitute for systems requiring a pilot burner ignition sequence.
