How do I light pilot light on furnace
The gas valve is an electrically powered device that is wired at the end of a series circuit so that it can only be energized (open) if all of the safety switches upstream in the circuit are closed and the pilot flame is lit on a standing pilot furnace.
The shutoff for your house is at the gas meter! The shutoffs otherwise are at each individual fixture. If you shutoff the main and do some work, you will have to purge the air and light every pilot on the individual fixtures as well. Better to get a licenced gas fitter for safety and insurance sakes.
There are a couple common reasons for a pilot light going out. 1. The thermocouple is weak. This is the gold rod that must see the flame in order to keep the gas valve open. it is a safety device that will not let the gas vavle open if there is no pilot. 2. The pilot is dirty and has a yellow flame. If this is the case, it will have to be cleaned. There are books on he market such as forced hot air furnace - troubleshooting and repair that show you how to repair your furnace. You can buy this at amazon.com
At pilot light, pilot light flows around thermocouple.
No standing pilot, it is a spark ignition unit
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
It's not necessary to clean it. If by any chance you have a problem and THINK you need to clean it, it's more likely the thermocouple is acting up and needs to be replaced.
No, but your furnace still does
