Carrier LH33WZ019 Ignitor Assembly
The Carrier LH33WZ019 Ignitor Assembly is a critical OEM replacement component designed for precise ignition sequences in Carrier, Bryant, and Payne gas-fired furnaces. This hot surface ignitor (HSI) is engineered with high-grade silicon carbide to withstand rapid thermal cycling and high-temperature environments. It functions by reaching necessary ignition temperatures via electrical resistance before the gas valve opens, ensuring a reliable flame sense and consistent pilotless ignition. As a direct-fit factory part, the LH33WZ019 maintains the integrity of the furnace control board’s diagnostic cycles, preventing nuisance lockouts caused by secondary market components with inconsistent resistance values. When performing a furnace ignitor replacement, this assembly provides the exact amperage draw required by the HVAC induction motor and gas manifold system. Contractors prefer this genuine Carrier furnace part for its durability and precise fitment in compatible condensing and non-condensing furnaces, ensuring the heating system operates at peak efficiency during high-demand cycles.
Key Benefits for Technicians- OEM Compatibility: Precision-engineered for exact fitment in Carrier LH33WZ019 applications, eliminating the need for bracket modifications.
- High-Durability Material: Constructed from premium silicon carbide to resist oxidation and thermal shock over heavy furnace duty cycles.
- Reliable Ignition: Provides consistent hot surface ignition to reduce delayed ignition issues and promote smooth burner transitions.
- Standardized Electrical Specs: Matches factory resistance requirements to ensure proper communication with the integrated furnace control (IFC).
- Complete Assembly: Includes necessary wiring and connectors for a streamlined field installation.
Is the Carrier LH33WZ019 compatible with older Bryant furnaces?
Yes, this ignitor assembly is a standard replacement for many Bryant and Payne models. Verify the part number against your existing service manual or the label on the induction blower housing.
What causes this ignitor to fail prematurely?
Common causes include carbon buildup, improper handling (touching the element with bare hands), or excessive voltage spikes from a faulty furnace control board.
How do I test the LH33WZ019 during a service call?
Use a multimeter to check for continuity or measure the ohms resistance at the connector. An open circuit or resistance outside of factory range indicates the furnace ignitor needs replacement.
