What to Do When Your Furnace Pilot Light Keeps Going Out

Having a pilot light on your furnace that can’t seem to stay lit is an issue that needs to be resolved as soon as possible. Imagine having to endure the cold winter while your furnace is out of commission! We’ve outlined a few steps to figure out how to stay warm while resolving the issue of your furnace pilot light going out.

Check Your Gas Pressure

The main issue of having a furnace pilot light that keeps going out is that the gas pressure can be off. Testing your gas pressure is the best way to determine whether or not this is the problem, and you can do it without having to call a technician. The gas pressure test ensures that the pressure is not to strong or too weak.

First, make sure the gas is turned off before you test your gas pressure otherwise you can put yourself in danger. Then, using a gas pressure tester, check the pressure until the needle is pointing to the correct number. The correct numbers can be found in the owner’s manual that came with your furnace. If the needle is off, resetting your pressure may do the trick.

Clean Your Pilot Light

You should take the time to clean your pilot light regularly. The pilot light may be littling sporadically due to dirt, dust, and grime gathering at the end of the pilot light. It’s recommended that you use a can of compressed air to clean the pilot light before relighting it.

To do this correctly, you want to make sure that all the power sources to your furnace, including the gas and the switch, are turned off. Then, put the can of compressed air nozzle directly in front of the pilot light, making sure not to bend the actual light, and spray the entire surface evenly. You may have to do this a few times, so keep going until you think the flint and spark igniter, where these two elements meet, is all cleared of the dirt.

Contact a Technician to Check for Gas Leaks

Still having issues with your pilot light? The problem could be more complicated than just dirt in your pilot light and could require the help of a professional furnace technician.

Our technicians can ensure that your entire furnace system is in tip-top shape, from the gas pressure to the gas components. We can also check for any gas leaks that may be occurring, which can be a common cause of a pilot light that won’t stay lit.

The point of having the technicians come out and run the tests is to find the exact cause of the issue. Without knowing the root of the problem, you’re just guessing and trying to fix the problem without success.


Having a furnace that won’t stay lit is a problem that nobody wants to deal with. However, the steps outlined above should be able to help you troubleshoot the problem or have a professional technician come out and assess the issue.

Pilot Light Keeps Going Out

There are a few different things that can cause pilot lights to keep going out, and it is important to take precautions to prevent this issue from occurring in the first place. The following is a list of recommendations from manufacturers and local HVAC technicians in San Diego to help prevent pilot light keeps going out issues:

  • Check for leaks. Before starting any work on the appliance, check for gas or oil leaks around the appliance and the area in order to prevent potential fire hazards or other safety risks.

  • Check for blockages. Check for blockages in the vent pipe, oranger spark plug or air filters on the appliance. Blockages can block the pilot light from receiving enough gas, preventing the pilot from staying lit.

  • Clean and maintain the appliance. Properly clean and maintain the appliance according to the manufacturer’s directions. This can help to ensure that the appliance is functioning correctly and prevent any potential problems from arising.

  • Check the thermocouple. The thermocouple is a safety device on the appliance that shuts off the gas to the appliance if the pilot light goes out suddenly. Make sure the thermocouple is working properly and check to make sure there is no corrosion, dirt or dust in the area that could be interfering with the device.

  • Check the right connections. Make sure all connections and tubing are properly sealed and tightened. This helps to ensure that the pilot light receives enough gas and will stay lit.

  • Replace the Pilot Light. If necessary, replace the pilot light itself if it is cracked, damaged or worn out.

Following these recommendations can help to prevent pilot light keeps going out issues and ensure that the appliance is running properly. If the issue persists, contact a professional appliance or HVAC technician for assistance.
