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

A faulty furnace is exhausting to put up with. There are lots of reasons this can happen, but one of the most frequent is something wrong with the burners or relevant systems.

Newer models don’t count on pilot lights to keep the furnace ignited. Instead, they work via electronic ignition. If this ignition is damaged, the burners can’t work like they should.

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

    • The thermostat informs your furnace to run.
    • Your furnace’s draft inducer fan begins to spin in order to bring fresh air through your furnace.
    • The gas valve opens to direct gas into the pilot burner.
    • An electronic spark lights the pilot light.
    • The flame sensor tells your furnace that the pilot has been lit.
    • The gas valve moves gas to the principal burners, which are lit by the pilot light.
    • Your furnace then pushes warm air throughout your home via ductwork.

If something breaks down 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 problems can be resolved on their own, but others require professional servicing. When you are looking for the finest furnace repair in the U.S., reach out to our heating Experts at . We work with all brands and our work is supported by a 100% Satisfaction Guarantee for a year.*

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

1. Faulty 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 damaged, it may work intermittently or not at all. Even if the sensor is running normally, incorrect positioning leaves it unable to detect the flame to begin with. While you could start troubleshooting and cleaning this sensor by yourself, contacting an expert like Service Experts Heating, Air Conditioning & Plumbing will ensure the problem is resolved quickly and correctly.

2. Overheated Furnace

Your furnace has built-in safety procedures that force a shutdown if it gets especially hot. One of the most typical causes is a filthy filter. We suggest evaluating your air filter each month. If you can’t see light through it, change it.

3. Thermostat Isn’t Working Right

Your thermostat commands your furnace when it needs to heat your home. When it’s not running as it’s supposed to, your furnace will struggle to keep your home warm. This can be a battery or electrical malfunction, depending on what type of thermostat you use. We encourage reviewing your owner’s manual or manufacturer’s website for required troubleshooting info. If you still can’t get yours working, contact our Experts at . We’ll uncover the problem swiftly and can replace your thermostat, if needed.

A number of these issues, such as a dirty flame sensor or an overheated furnace, are caused by a lack of consistent furnace maintenance. It’s extremely helpful to have this service performed yearly, because it might help stop breakdowns, increase your furnace’s energy efficiency and can even make it live longer.
