With greenspeed intelligence and variable speed components you can avoid wasting money for heating capacity you don t need.
Carrier furnace electronic pilot light.
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.
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.
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.
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.
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.
This system uses a pilot flame but the flame lights only when there s a call for heat from the thermostat.
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 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.
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.
Pilot free savings and reliability.
Lighting a pilot that is electronic ignition resources for gas heating gas heating for furnaces and boilers basics.
There are two basic types of electronic igniters in modern furnaces.
The most common reason for this problem is because the pilot light is not on.
When the thermostat signals the need for heat an electric system creates a spark that causes the pilot to.
Step 3 find the ignition button turn the furnace back on.
When your furnace fails to ignite the first place to look is the pilot light.
Instead the pilot light only comes on when it needs to ignite the burner.
A hot surface ignition system uses an electronically controlled resistance heating element not unlike a light bulb filament to ignite the gas burner.
