A faulty furnace is a hassle to deal with. There are multiple reasons this may happen, but one of the most likely is a problem with the burners or relevant systems.
Newer models don’t depend on pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition fails, the burners won’t function like they should.
When your gas furnace is performing normally, here’s how it should run:
- The thermostat tells your furnace to run.
- Your furnace’s draft inducer fan starts to draw fresh air through your furnace.
- The gas valve opens to move gas into the pilot burner.
- An electronic spark ignites the pilot light.
- The flame sensor tells your furnace that the pilot has been lit.
- The gas valve directs gas to the principal burners, which are lit by the pilot light.
- Your furnace then distributes warm air into your residence via ductwork.
If something malfunctions during this process, your furnace will turn off for safety reasons. Or it might shut down a few minutes into heating because it’s getting too hot.

Here are several of the top 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 component that tells your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it may work inconsistently or not at all. Even if the sensor is functioning like it should, misaligned positioning leaves it unable to recognize the flame to begin with. While you can attempt troubleshooting and cleaning this sensor right away, contacting a pro like Bob Brown Service Experts will guarantee the problem is taken care of swiftly and correctly.
2. Furnace is Too Hot
Your furnace has built-in safety features that force a shutdown if it gets dangerously hot. One of the most common causes is a filthy filter. We suggest evaluating your air filter each month. If you can’t see light through it, replace it.
3. Thermostat Malfunction
Your thermostat informs your furnace when it needs to heat your home. When it’s not working like it should, your furnace will struggle to keep your house warm. This can be a battery or electrical issue, depending on what kind of thermostat you use. We recommend checking your owner’s manual or manufacturer’s website for required troubleshooting information. If you still can’t get yours working, reach out to our Experts at 623-243-4517. We’ll uncover the cause swiftly and can replace your thermostat, if necessary.
Some of these issues, such as a dirty flame sensor or an overheated furnace, are a result of a lack of routine furnace maintenance. It’s vital to have this service completed annually, because it can help minimize breakdowns, improve your furnace’s energy efficiency and might even make it last longer.
