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

A malfunctioning furnace is frustrating to handle. There are several reasons this can happen, but one of the most frequent is something wrong with the burners or associated parts.

Newer furnaces don’t depend on pilot lights to keep the furnace ignited. Instead, they use electronic ignition. If this ignition malfunctions, the burners can’t function like they should.

When your gas furnace is performing normally, here’s how it should operate:

    • The thermostat informs your furnace to run.
    • Your furnace’s draft inducer fan starts to pull fresh air into your furnace.
    • The gas valve opens to move gas into the pilot burner.
    • An electronic spark ignites the pilot light.
    • The flame sensor tells your furnace that the pilot is burning.
    • The gas valve moves gas to the central burners, which are lit by the pilot light.
    • Your furnace then distributes warm air into your residence via ductwork.

If something malfunctions during this procedure, your furnace will deactivate for safety purposes. Or it might deactivate a few minutes into heating because it’s overheating.

A number of of these issues can be repaired on their own, but others are best handled by professional assistance. When you need the finest furnace repair in the U.S., contact our heat Experts at . We work with all brands and our services are supported by a 100% Satisfaction Guarantee for a year.*

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

1. Faulty Flame Sensor

Your furnace’s flame sensor is a safety component that tells your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it may work inconsistently or not at all. Even if the sensor is operating like it should, poor positioning leaves it unable to detect the flame to begin with. While you may start troubleshooting and cleaning this sensor right away, hiring a professional like Service Experts Heating, Air Conditioning & Plumbing will make sure the problem is fixed swiftly and correctly.

2. Overheated Furnace

Your furnace utilizes built-in safety features that deactivates your furnace if it gets too hot. One of the most common causes is a clogged filter. We suggest 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 should heat your residence. When it’s not working as it’s supposed to, your furnace will require more energy to keep your home warm. This can be a battery or electrical malfunction, depending on what kind of thermostat you own. We suggest referring to your owner’s manual or manufacturer’s website for required troubleshooting instructions. If you still can’t get yours working, reach out to our Experts at . We’ll discover the issue quickly and can replace your thermostat, if that is required.

Some of these issues, like a dirty flame sensor or an overheated furnace, are a result of a lack of consistent furnace maintenance. It’s crucial to have this service done yearly, because it could help stop breakdowns, improve your furnace’s energy efficiency and may even make it live longer.
