3 Explanations Why Your Furnace Isn’t Staying Lit and How to Fix It

A damaged furnace is frustrating to put up with. There are lots of reasons this may happen, but one of the most common is an issue with the burners or associated systems.

Newer furnaces don’t depend on pilot lights to keep the furnace ignited. Instead, they utilize electronic ignition. If this ignition is damaged, the burners will not work like they should.

When your gas furnace is functioning normally, here’s how it should work:

    • The thermostat informs your furnace to turn on.
    • Your furnace’s draft inducer fan begins to spin in order to draw fresh air toward your furnace.
    • The gas valve opens to direct gas into the pilot burner.
    • An electronic spark lights the pilot light.
    • The flame sensor directs your furnace that the pilot has been lit.
    • The gas valve transports gas to the primary burners, which are lit by the pilot light.
    • Your furnace then provides warm air into your house via ductwork.

If something fails during this process, your furnace will stop for safety reasons. Or it might turn off a few minutes into heating because it’s overheating.

Some of these malfunctions can be fixed on their own, but others require professional assistance. When you are looking for the fastest furnace repair in the U.S., call our furnace Experts at . We repair all brands and our work is backed by a 100% Satisfaction Guarantee for a year.*

Here are a few of the most common reasons why your furnace 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 informs your furnace when gas is ignited. If the sensor is dirty or faulty, it might work erratically or not at all. Even if the sensor is functioning normally, incorrect positioning leaves it unable to sense the flame at all. While you can start troubleshooting and cleaning this sensor right away, calling a pro like Service Experts Heating, Air Conditioning & Plumbing will make sure the problem is handled promptly and correctly.

2. Furnace is Too Hot

Your furnace has built-in safety procedures that deactivates your furnace if it gets especially hot. One of the most typical causes is a dirty filter. We recommend reviewing your air filter each month. If you can’t see light through it, replace it.

3. Thermostat is Malfunctioning

Your thermostat informs your furnace when it is time to heat your residence. When it’s not functioning normally, your furnace will struggle to keep your house warm. This can be a battery or electrical issue, depending on what type of thermostat you own. We suggest checking your owner’s manual or manufacturer’s website for required troubleshooting details. If you still can’t get yours working, reach out to our Experts at . We’ll discover the problem quickly and can replace your thermostat, if needed.

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 highly beneficial to have this service done every year, because it may help stop breakdowns, boost your furnace’s energy efficiency and can even make it live longer.
