What would cause a gas furnace not to light?
The Pilot Light (Faulty Ignition Sensor) The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite. This is typically the problem if you can hear your furnace click on but it does not fire up. If the sensor or ignitor is dirty, it will need to be cleaned.
Why is the pilot light not lit on my gas furnace?
Your furnace will still have a flame sensor, but it will be over the burner’s flame. If you have a furnace with a standing pilot light, step 4 won’t happen. Your pilot light will be lit (by you) before any of the other steps happen. Side note: you may want to consider getting a new furnace since yours is very old and inefficient.
What does it mean when your furnace is not igniting?
The oldest way is by a pilot light and over the last 30 years or so these have been replaced by electronic ignition systems. If these fail to do their job your furnace will not come on. This is a small flame which is constantly burning inside your furnace. It’s so small it does not consume much gas.
What to do if your furnace won’t stay lit?
When you have a problem with a condensing furnace not staying lit, you may want to check the PVC pipe on the outside of the home to check for an occlusion (birds nest, kids toy, wasp nest…etc.). The pressure switch is a round shaped control mounted near the top of the furnace close to the draft inducer fan.
Where can I get a gas furnace to relight?
Hi, we have a 2016 Forest River Rockwood Signature Ultra Lite fifth wheel, and I cannot for the life of me get the pilot light to relight. It’s a Suburban gas furnace. We live in South Carolina and the nearest dealer is 55 miles away.

Get a needle and scrape the inside of the pilot tube. Any blockage in the pilot tube will cause the furnace to not stay lit. So cleaning it is an easy solution without having to replace any parts. Once cleaned out, put everything back in place and test out the furnace. You may need to replace the thermocouple on your gas furnace.
