Carrier Furnace Electronic Pilot Light

The pilot light is a small flame that is either lit manually and remains burning around the clock or is lit electronically via an igniter when the machine kicks on.

Carrier furnace electronic pilot light.

This system uses a pilot flame but the flame lights only when there s a call for heat from the thermostat. When your furnace fails to ignite the first place to look is the pilot light. Lighting the pilot light for a standing pilot gas system is possible whereas lighting the pilot for an electronic ignition system is possible if you have a backup generator or other source of power to power that circuit. An intermittent pilot system uses an electronically controlled high voltage electric spark to ignite a pilot light and subsequently the main burners when the thermostat calls for heat.

With greenspeed intelligence and variable speed components you can avoid wasting money for heating capacity you don t need. There are two basic types of electronic igniters in modern furnaces. Intermittent pilots still use a pilot light however it isn t a standing pilot light that remains on all the time to ignite the burner whenever the gas turns on. 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.

Instead the pilot light only comes on when it needs to ignite the burner. Pilot free savings and reliability. In turn the pilot lights the gas for the burners. The furnace s electronic control board activates an electric igniter that uses a high voltage spark to light the pilot.

One type of electronic ignition is an intermittent pilot. First you may want to turn the furnace off and disconnect the gas giving the air time to clear in case gas has been leaking out of the pilot. Hot surface igniters and intermittent pilots. If all systems are working then you re ready to try to light the pilot.

Lighting a pilot that is electronic ignition resources for gas heating gas heating for furnaces and boilers basics. While older pilots burned constantly wasting gas automatic pilot lights come on long enough to ignite the gas supply and then shut off. Step 3 find the ignition button turn the furnace back on. The most common reason for this problem is because the pilot light is not on.

Carrier gas furnaces with greenspeed intelligence monitor temperature and humidity inside and out then automatically vary furnace operation as needed to provide an ideal combination of comfort and energy efficiency.
