How to Repair a Furnace That Wont Stay Lit

A faulty furnace is exhausting to deal with. There are multiple reasons this can happen, but one of the most frequent is an issue with the burners or associated components.

Newer models don’t require pilot lights to keep the furnace ignited. Instead, they work via electronic ignition. If this ignition stops working correctly, the burners won’t function like they do normally.

When your gas furnace is running correctly, here’s how it should operate:

  • The thermostat directs your furnace to turn on.
  • Your furnace’s draft inducer fan begins to spin in order to pull fresh air through your furnace.
  • The gas valve opens to move gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor tells your furnace that the pilot is burning.
  • The gas valve transports gas to the central burners, which are lit by the pilot light.
  • Your furnace then provides warm air across your residence via ductwork.

If something fails during this procedure, your furnace will deactivate for safety concerns. Or it might deactivate a few minutes into heating because it’s too warm.

Several of these malfunctions can be fixed on their own, but others require professional help.

Here are some of the most common reasons why your furnace isn’t staying lit and what to do moving forward.

1. Dirty 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 faulty, it might work intermittently or not at all. Even if the sensor is operating normally, misaligned positioning leaves it unable to sense the flame to begin with. While you may start troubleshooting and cleaning this sensor on your own, calling a pro like Epperson Service Experts will make sure the problem is handled quickly and correctly.

2. Furnace is Too Hot

Your furnace has built-in safety features that deactivates your furnace if it gets too hot. One of the most common causes is a dirty filter. We encourage checking 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 should heat your residence. When it’s not running properly, your furnace will require more energy to keep your residence warm. This can be a battery or electrical issue, depending on what kind of thermostat you own. We recommend referring to your owner’s manual or manufacturer’s website for relevant troubleshooting procedures. If you still can’t get yours working, contact our Experts at 843-619-3781. We’ll find the problem promptly and can replace your thermostat, if necessary.

A number of these issues, such as a dirty flame sensor or an overheated furnace, are a result of a lack of proper furnace maintenance. It’s crucial to have this service performed yearly, because it might help prevent breakdowns, enhance your furnace’s energy efficiency and could even make it survive longer.
