How To Light A Gas Furnace With Electronic Ignition

Unlike older pilot lights which have to be lighted by hand automatic pilot lights now commonly found in most home furnaces are regulated by a thermostat and only ignite when needed.

How to light a gas furnace with electronic ignition. Once the burn cycle is complete both the burners and the pilot turn off. Electronic ignition gas furnace problems troubleshooting gas furnaces are a prevalent form of heat for homes and businesses and occasionally a gas furnace needs to be repaired because of a problem with the gas furnace. In turn the pilot lights the gas for the burners. The burner and pilot shut off when the correct temperature is reached.

The second and more common type of electronic ignition system is the hot surface igniter. Never attempt to light a furnace by a flame manually especially if the furnace has an electronic igniter.
