Diversitech IG3033 Hot Surface Ignitor Trane Rooftop Units

Product Description

The DIVERSITECH IG3033 is a hot surface ignitor designed as a direct OEM-style replacement for select Trane package rooftop HVAC units. It functions as the ignition element responsible for initiating gas combustion in the burner box. The IG3033 includes 5 inch leads and a keyed connector that mates with factory wiring harnesses, simplifying installation and reducing the risk of miswiring. This part is installed by licensed HVAC technicians servicing commercial or light-commercial rooftop package equipment where reliable ignition is critical to system operation.

The IG3033 is suited for rooftop package unit applications where the original Trane ignitor assembly has failed or degraded. Hot surface ignitors in this class typically fail due to thermal cycling, cracking, or contamination, and a direct-replacement element like the IG3033 restores reliable ignition without requiring harness modification. Verify the specific Trane model and original ignitor part number before installation to confirm fitment for the unit being serviced.

Key Features

• Hot surface ignition element for gas combustion initiation in the burner box
• 5 inch leads for direct connection to the existing wiring harness
• Keyed connector matches factory Trane harness plug, preventing incorrect orientation
• Direct OEM-style replacement reduces installation time on service calls
• Designed for use in package rooftop HVAC systems

Compatibility

Designed as a direct OEM-style replacement ignitor for select Trane package rooftop HVAC units. Verify the specific Trane model number and original ignitor part number prior to ordering to confirm correct fitment.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut off gas supply and disconnect electrical power to the unit at the disconnect switch before removing the existing ignitor. Hot surface ignitors are fragile ceramic components — handle the element by its mounting bracket and leads only, avoiding contact with the ignitor surface. Confirm ignitor resistance and circuit voltage with a meter after installation to verify proper operation before returning the unit to service.
