3 Reasons Why Your Furnace Isn’t Staying Lit and How to Solve It

A malfunctioning furnace is exhausting to put up with. There are several reasons this may happen, but one of the most common is a problem with the burners or related parts.

Newer systems 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 work like they are supposed to.

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

    • The thermostat informs your furnace to turn on.
    • Your furnace’s draft inducer fan starts to draw fresh air toward your furnace.
    • The gas valve opens to move gas into the pilot burner.
    • An electronic spark ignites the pilot light.
    • The flame sensor informs your furnace that the pilot has been ignited.
    • The gas valve sends gas to the central burners, which are lit by the pilot light.
    • Your furnace then provides warm air into your residence via ductwork.

If something malfunctions during this process, your furnace will shut down for safety purposes. Or it might deactivate a few minutes into heating because it’s too warm.

Some of these issues can be repaired on their own, but others need professional servicing. When you are looking for the finest furnace repair in the U.S., contact our heat Experts at . We work with all brands and our work is backed by a 100% Satisfaction Guarantee for a year.*

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

1. Malfunctioning 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 damaged, it may work erratically or not at all. Even if the sensor is running normally, poor positioning leaves it unable to sense the flame to begin with. While you could try troubleshooting and cleaning this sensor on your own, hiring a pro like Service Experts Heating, Air Conditioning & Plumbing will guarantee the problem is handled swiftly and correctly.

2. Overheated Furnace

Your furnace has built-in safety functions that shut it off if it gets too hot. One of the most typical causes is a clogged filter. We recommend inspecting your air filter each month. If you can’t see light through it, swap it out.

3. Thermostat Isn’t Working Right

Your thermostat directs your furnace when it needs to heat your residence. When it’s not functioning normally, your furnace will require more energy to keep your house warm. This can be a battery or electrical issue, depending on what model of thermostat you have. We encourage referring to your owner’s manual or manufacturer’s website for specific troubleshooting info. If you still can’t get yours working, contact our Experts at . We’ll identify the cause 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 routine furnace maintenance. It’s crucial to have this service done yearly, because it could help reduce breakdowns, enhance your furnace’s energy efficiency and might even make it live longer.
