The furnace s electronic control board activates an electric igniter that uses a high voltage spark to light the pilot.
Carrier furnace electronic pilot light.
While older pilots burned constantly wasting gas automatic pilot lights come on long enough to ignite the gas supply and then shut off.
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.
When the thermostat signals the need for heat an electric system creates a spark that causes the pilot to.
Pilot free savings and reliability.
Instead the pilot light only comes on when it needs to ignite the burner.
Comfort 80 newcomb and company to the original owner the carrier comfort 80 gas furnace is covered by a 10 year parts and 20 year heat eliminates the need for a pilot light reducing gas usage and promoting worry free operation.
When your furnace fails to ignite the first place to look is the pilot light.
The most common reason for this problem is because the pilot light is not on.
With greenspeed intelligence and variable speed components you can avoid wasting money for heating capacity you don t need.
In turn the pilot lights the gas for the burners.
One type of electronic ignition is an intermittent pilot.
Lighting a pilot that is electronic ignition resources for gas heating gas heating for furnaces and boilers basics.
This system uses a pilot flame but the flame lights only when there s a call for heat from the thermostat.
Hot surface igniters and intermittent pilots.
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.
There are two basic types of electronic igniters in modern furnaces.
Step 3 find the ignition button turn the furnace back 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.
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.
A hot surface ignition system uses an electronically controlled resistance heating element not unlike a light bulb filament to ignite the gas burner.
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.
