LH33WZ008
The Carrier LH33WZ008 is an essential part of the ignition of the gas burner in Carrier HVAC systems. It is essential to the startup process. During a heating cycle, the LH33WZ008 ignitor produces a spark through high voltage electricity to ignite the gas. This spark then ignites the gas, which is in a continuous flow to the burner to start a combustion process that warms your home. Manufactured from high quality materials, the LH33WZ008 is built to endure the heat that is inside the furnace. This ignitor assures a constant and efficient spark each time, thus eliminating cases of failed ignitions with the resultant difficulties and possible dangers.
