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

A damaged furnace is a hassle to put up with. There are many reasons this might happen, but one of the most frequent is an issue with the burners or related components.

Newer furnaces don’t use pilot lights to keep the furnace going. Instead, they use electronic ignition. If this ignition fails, the burners can’t perform like they should.

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

  • The thermostat informs your furnace to turn on.
  • Your furnace’s draft inducer fan begins to spin in order to bring fresh air toward your furnace.
  • The gas valve opens to send gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor informs your furnace that the pilot is burning.
  • The gas valve directs gas to the central burners, which are lit by the pilot light.
  • Your furnace then sends warm air into your house via ductwork.

If something breaks down during this sequence, your furnace will turn off for safety reasons. Or it might stop a few minutes into heating because it’s getting too hot.

Some of these problems can be fixed on their own, but others require professional help. When you are looking for the best furnace repair in Fort Myers, call our furnace Experts at 239-908-6991.

Here are some of the most common reasons why your heater isn’t staying lit and what to do to fix it.

1. Faulty Flame Sensor

Your furnace’s flame sensor is a safety system that informs your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it may work erratically or not at all. Even if the sensor is running normally, incorrect positioning leaves it unable to sense the flame to begin with. While you could attempt troubleshooting and cleaning this sensor right away, hiring an expert like Service Experts Heating & Air Conditioning will ensure the problem is taken care of promptly and correctly.

2. Furnace is Too Hot

Your furnace utilizes built-in safety features that force a shutdown if it gets dangerously hot. One of the most frequent causes is a dirty filter. We encourage inspecting your air filter each 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 home. When it’s not functioning correctly, your furnace will struggle to keep your house warm. This can be a battery or electrical malfunction, depending on what type of thermostat you use. We recommend reviewing your owner’s manual or manufacturer’s website for required troubleshooting info. If you still can’t get yours working, get in touch with our Experts at 239-908-6991. We’ll find the problem quickly and can replace your thermostat, if necessary.

A number of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of proper furnace maintenance. It’s important to have this service completed yearly, because it may help reduce breakdowns, increase your furnace’s energy efficiency and could even make it survive longer.
