There are several possible reasons why your furnace pilot light won't stay lit. It could be due to a dirty or faulty thermocouple, a clogged pilot orifice, a draft in the area, or a problem with the gas supply. It's best to have a professional HVAC technician inspect and repair the issue to ensure safe and efficient operation of your furnace.

Could be lots of things. If you have a standing pilot light, one that stays on all the time, the thermocouple may be bad. A thermocouple is a small rod that sits in the flame of the pilot light. It then runs to the gas valve. This produces a small amount of electricity that keeps the valve open to let the gas in. If the pilot light goes out it shuts the valve so the house doesn't blow up. Easy enough to replace. If the pilot light is still on and the furnace will not light, it has to be the thermocouple. Check fuses at the furnace and in the panel. Newer gas furnaces have a circuit board in them that can go bad. There are a dozen things that could keep it from working, it is just a process of elination.

Your hot water heaters pilot light is on but the heater wont come on?
The thermocouple is bad. The thermocouple is the small metal tube that sits in the pilot light flame and runs to the control valve. The thermocouple generates a very small electrical current that keeps the gas valve open. They go bad regularly. **** I would have to say to check to make sure the valve is not in the "Pilot" position. If it is then turn it to the "On' position. If it still isn't working then you may have a bad Gas Control Valve. If the thermocouple was bad the pilot light would not stay lit. If the pilot light stay lit, it is doing what it is supossed to do.

Pilot light is on but flames wont light when you turn up the thermostat?
This question is not specific enough for a good answer. What is the appliance? A furnace? A cooktop burner? An oven? The first thing to check would be the igniter, which is what typically "lights" the gas coming from the valve. You can check an igniter with a simple continuity test using a test meter. If the pilot is lit, then there is no igniter, or the igniter lites the pilot, so if the pilot is lit how could it be the igniter. Bad thermocouple, this tells the gas valve that the pilot light is lit, if the gas valve does not know the pilot is lit it will not allow gas to come out of the valve, this is a safety feature so your unit does not blow up.

Check the starting directions, most gas heater pilots must have the button depressed for more than 30 seconds. If this does not work there is a problem with the regulator.

Here are some things to check. Is the thermostat turned up? Sounds silly but I went into many homes it was turned down, or the switch on the thermostat was turned to off Is the pilot lit? This assumes you have a standing pilot furnace. If it is spark ignition, does the park cycle start. Check all fuses and breakers
