What causes low pilot?
Some of the reasons your pilot light keeps going out include: A poor pilot flame – low gas pressure or blocked orifice. A flame that is set too small. An insufficient supply of gas.
What does weak pilot signal mean?
That can be caused by numerous things, but a few of them are: lint or dirt buildup in the air inlet screen, crud in the gas valve that is preventing the proper amount of gas to get to the pilot, soot accumulation on the thermocouple, a poor connection of the thermocouple to the control, or a bad thermocouple.
What to do if your pilot light flame is too high?
So, if your pilot light flame also tends to be too high, ensure that your fireplace doesn’t have a button to bring the flame up or downward. If there’s no such button, adjust a screw on the fireplace. Turning it clockwise will reduce the fire whilst moving the opposite direction will raise it.
Why is my furnace pilot light too small?
If in doubt, make small adjustments to the screw/bolt and check the visible size of the flame while the pilot light is lit. Sometimes during regular cleaning, or due to vibration of the unit, this adjustment can accidentally be turned down, resulting in a flame that is too small.
What happens when the pilot light is out on a gas fireplace?
If the pilot light is out, though, such a signal isn’t sent. This catch-22 can cause issues with your fireplace. Ideally, your pilot light should burn blue, but at times you’ll find it’s orange or yellow.

The pilot light flame needs to completely envelop the top of the thermocouple rod so it knows the flame is on. If the thermocouple isn’t lined up correctly, it won’t read the flame, and will shut the valve for the gas. I’m not touching it. Help me!
What does it mean when your pilot light is not working?
Pilot light problems that require professional attention. Inefficient function. If your pilot light is burning but has a weak, yellow flame, it is not working efficiently enough.

If the pilot flame is too small, you may be able to make it larger by turning the pilot adjustment screw on the valve control counterclockwise with a screwdriver to open it. If this screw isn’t labeled, consult the appliance owner’s manual to identify it. The cause of a weak flame may also be an obstruction in the pilot tube.
Why does the pilot light on my fireplace go off?
Thermocouple provides the signal that lets the pilot light stay on. The light provides the temperature needed for the thermocouple to work. This dependence is one of the main reasons for issues in the fireplace work. If you can’t turn on your fireplace or the pilot light goes off you should check the system for the problems.
