Trane Hot Surface Ignitor for Gas Furnaces

The Trane hot surface ignitor for gas furnaces is a replacement furnace igniter (also called a hot surface igniter or HSI) that lights the main burners in a modern gas furnace. When the thermostat calls for heat, the ignitor heats up until it glows and ignites the gas. This replaces the standing pilot light, so the furnace uses less gas.

Key Features:

• Designed as a replacement ignitor for Trane gas-fired furnaces
• Heating element glows hot to ignite the gas at the burners reliably
• Helps restore dependable startup and consistent heat when a furnace fails to ignite
• Replaces worn, cracked, or burned-out ignitors, a common cause of no-heat and failed-ignition problems
• Works with the furnace control board's ignition sequence

Handle with care: The ignition element is fragile. Avoid touching it with bare hands, because skin oils can shorten its life. Turn off power and gas to the furnace before replacing it.
