3 Causes Why Your Furnace Isnt Staying Lit and How to Solve It

A malfunctioning furnace is a hassle to handle. There are multiple reasons this can happen, but one of the most common is something wrong with the burners or related parts.

Newer furnaces don’t require pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition malfunctions, the burners won’t perform like they do normally.

When your gas furnace is performing correctly, here’s how it should run:

  • The thermostat directs your furnace to activate.
  • Your furnace’s draft inducer fan starts to draw fresh air into 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 directs gas to the main burners, which are lit by the pilot light.
  • Your furnace then transports warm air across your home via ductwork.

If something fails during this process, your furnace will deactivate for safety reasons. Or it might deactivate a few minutes into heating because it’s getting too hot.

A number of of these malfunctions can be repaired on their own, but others require professional servicing.

Here are some of the typical reasons why your heating isn’t staying lit and what to do about it.

1. Dirty Flame Sensor

Your furnace’s flame sensor is a safety feature that informs your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it may work intermittently or not at all. Even if the sensor is functioning like it should, incorrect positioning leaves it unable to identify the flame entirely. While you may attempt troubleshooting and cleaning this sensor right away, trusting a professional like Stallion Heating Plumbing Air Conditioning will ensure the problem is fixed quickly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety features that force a shutdown if it gets dangerously hot. One of the most common causes is a clogged filter. We encourage inspecting your air filter every month. If you can’t see light through it, replace it.

3. Thermostat Isn’t Working Right

Your thermostat directs your furnace when it needs to heat your residence. When it’s not running correctly, your furnace will require more energy to keep your house warm. This can be a battery or electrical malfunction, depending on what type of thermostat you own. We encourage referring to your owner’s manual or manufacturer’s website for necessary troubleshooting details. If you still can’t get yours working, contact our Experts at 215-278-9690. We’ll discover the cause promptly and can replace your thermostat, if necessary.

A number of these issues, including a dirty flame sensor or an overheated furnace, are caused by a lack of proper furnace maintenance. It’s crucial to have this service performed annually, because it may help reduce breakdowns, improve your furnace’s energy efficiency and might even make it survive longer.
