You sould be able to see it either in the open or through a sight glass. If you have a continious pilot you just look at the burner where the furnace is open. Higher efficiency furnaces have an intermitent pilot that is only light when it is needed to light the main burner. And some do not have pilots at all and an ignightor lights the burner directly.
How do I light pilot light on furnace
Well I don't know if this works all the time but I tapped on the Combination control ( the thing that the main gas line comes in to with the switch for the pilot light is on) that thing and my furnace lit up. Like I said don't know why or how it worked but it did! Good luck
No standing pilot, it is a spark ignition unit
At pilot light, pilot light flows around thermocouple.
Defective thermocouple or possibly a dirty or clogged pilot orifice.
If this is happening you need to get your furnace serviced by a qualified engineer.
i have a model 125u19 payne furnace i move the thermostat but nothing comes on in the furnace and the pilot light is lit
Remove the pilot assembly from the furnace and clean it up. You need to be careful when putting it back on at the gas valve so as not to crossthread the screw. Take a thin wire and clean the pilot orifice, then use a brush or sandpaper on the thermocouple.
so when the pilot goes out the gas valve is shut off
None!
No, but your furnace still does
The gas furnace pilot (flame is lit all the time) is sometimes referred to as a pilot light, but no matter what you call it, its purpose is to serve as a small ignition flame for the gas burner. And when this little flame fails to operate properly or go out, it's one of the most common reasons a gas furnace will fail to operate.
