3 Reasons Why Your Furnace Isn’t Staying Lit and How to Fix It
A faulty furnace is tedious to handle. There are many reasons this may happen, but one of the most common is an issue with the burners or associated systems.
Newer furnaces don’t require pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition stops working correctly, the burners won’t function like they should.
When your gas furnace is performing normally, here’s how it should work:
- The thermostat tells your furnace to run.
- Your furnace’s draft inducer fan turns on to draw fresh air through your furnace.
- The gas valve opens to direct gas into the pilot burner.
- An electronic spark starts the pilot light.
- The flame sensor directs your furnace that the pilot has been ignited.
- The gas valve sends gas to the central burners, which are lit by the pilot light.
- Your furnace then pushes warm air across your residence via ductwork.
If something malfunctions during this process, your furnace will turn off for safety purposes. Or it might shut down a few minutes into heating because it’s overheating.
Several of these problems can be handled on their own, but others are best handled by professional help.

Here are several of the most common reasons why your furnace isn’t staying lit and what to do moving forward.
1. Malfunctioning Flame Sensor
Your furnace’s flame sensor is a safety system that tells your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it might work erratically or not at all. Even if the sensor is operating as normal, poor positioning leaves it unable to detect the flame to begin with. While you may try troubleshooting and cleaning this sensor right away, calling a pro like Service Experts Heating, Air Conditioning & Plumbing will make sure the problem is resolved swiftly and correctly.
2. Furnace is Too Warm
Your furnace has built-in safety procedures that shut it off if it gets too hot. One of the most frequent causes is a filthy filter. We encourage inspecting your air filter each month. If you can’t see light through it, swap it out.
3. Thermostat Isn’t Working Right
Your thermostat directs your furnace when it should heat your home. When it’s not running like it should, your furnace will require more energy to keep your residence warm. This can be a battery or electrical problem, depending on what kind of thermostat you use. We encourage reviewing your owner’s manual or manufacturer’s website for necessary troubleshooting information. If you still can’t get yours working, get in touch with our Experts at 866-397-3787. We’ll find the cause swiftly and can replace your thermostat, if needed.
Some of these issues, like a dirty flame sensor or an overheated furnace, are due to a lack of consistent furnace maintenance. It’s vital to have this service done yearly, because it may help prevent breakdowns, boost your furnace’s energy efficiency and may even make it last longer.
