Relighting Your Heaters Pilot Light

Standing pilot furnaces occasionally need to have their pilot lights relit. You can always call your local expert heating contractor if you think the problem is severe, but this blog will help you identify and relight your pilot light all on your own.

Identify the Pilot

To identify the pilot light, follow the gas line to your furnace and the gas valve. The gas valve has a switch that shows on, pilot, and off. The small tube that comes out of the gas valve will lead you to the pilot light and thermocouple safety measure.

Safety First

Make sure to switch the gas valve to “off” and let the furnace cool off for 5 minutes. If you smell gas, close the gas line and call a professional if you think it’s a leak.


Now, set the gas valve to the pilot position and hold down the bypass button to send gas to the pilot. Take a barbecue lighter and insert it at the nose of the pilot. Light the flame to ignite the pilot light. Keep the bypass button held down for 30 seconds to keep the flame burning until the thermocouple heats up.

Set the gas valve to the on position and set your thermostat to the desired temperature. If the pilot light keeps going out, it may be a problem with the thermocouple, which will need cleaning.
