How to Repair a Furnace That Wont Stay Lit

A malfunctioning furnace is frustrating to handle. There are multiple reasons this may happen, but one of the most likely is a problem with the burners or related components.

Newer systems don’t depend on pilot lights to keep the furnace lit. Instead, they use electronic ignition. If this ignition fails, the burners will not function like they do normally.

When your gas furnace is running normally, here’s how it should run:

  • The thermostat directs your furnace to turn on.
  • Your furnace’s draft inducer fan begins to spin in order to bring fresh air into your furnace.
  • The gas valve opens to direct gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor tells your furnace that the pilot has been ignited.
  • The gas valve transports gas to the principal burners, which are lit by the pilot light.
  • Your furnace then sends warm air throughout your residence via ductwork.

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

A number of of these issues can be fixed on their own, but others are best handled by professional servicing.

Here are a number of the top reasons why your heating isn’t staying lit and what to do to fix it.

1. Malfunctioning Flame Sensor

Your furnace’s flame sensor is a safety feature that tells your furnace when gas is ignited. If the sensor is dirty or damaged, it may work inconsistently or not at all. Even if the sensor is functioning as normal, poor positioning leaves it unable to identify the flame entirely. While you may attempt troubleshooting and cleaning this sensor on your own, hiring an expert like Falso Service Experts will ensure the problem is resolved quickly and correctly.

2. Furnace is Too Warm

Your furnace utilizes built-in safety features that shut it off if it gets too hot. One of the most frequent causes is a dirty filter. We suggest inspecting your air filter monthly. If you can’t see light through it, change it.

3. Thermostat Isn’t Working Right

Your thermostat informs your furnace when it should heat your home. When it’s not functioning properly, your furnace will require more energy to keep your residence warm. This can be a battery or electrical issue, depending on what model of thermostat you use. We recommend reviewing your owner’s manual or manufacturer’s website for needed troubleshooting info. If you still can’t get yours working, get in touch with our Experts at 315-313-6531. We’ll uncover the cause swiftly and can replace your thermostat, if that is required.

Several of these issues, like a dirty flame sensor or an overheated furnace, are due to a lack of proper furnace maintenance. It’s highly beneficial to have this service performed every year, because it can help stop breakdowns, enhance your furnace’s energy efficiency and may even make it last longer.
