Lochinvar LPLT3400 Hot Surface Ignitor

Product Description

The LOCHINVAR LPLT3400 is a hot surface ignitor designed to provide reliable ignition in heating systems. Hot surface ignitors replace the older spark-ignition and standing-pilot designs, using a resistive element that heats to ignition temperature when voltage is applied. This part is installed by licensed HVAC technicians during routine maintenance, system commissioning, or ignitor failure calls. It is built to match OEM specifications, supporting consistent burner light-off and reducing nuisance lockouts caused by failed ignition events.

The LPLT3400 is suited for heating applications where a direct OEM-style replacement ignitor is required. Technicians typically encounter this part during seasonal tune-ups or no-heat service calls. It is appropriate for heating system environments where the original ignitor has cracked, broken, or degraded to the point of inconsistent or failed ignition.

Key Features

• OEM-style replacement hot surface ignitor for heating applications
• Resistive element design heats to ignition temperature on voltage application
• Built to match original specifications for consistent burner light-off
• Reduces nuisance lockouts associated with ignitor degradation or failure

Compatibility

Designed as an OEM-style replacement hot surface ignitor for LOCHINVAR heating systems and equipment requiring this ignitor type.

Installation Notes

Hot surface ignitors are installed by qualified HVAC technicians. Always shut off power and gas supply to the appliance before beginning ignitor replacement. Handle the ignitor element carefully and avoid touching the ceramic or silicon nitride tip with bare hands, as skin oils can cause premature failure. Verify that the replacement ignitor is fully seated and the electrical connector is secure before restoring power and performing an ignition test.
