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

A damaged furnace is frustrating to handle. There are multiple reasons this can happen, but one of the most common is something wrong with the burners or relevant components.

Newer models don’t require pilot lights to keep the furnace ignited. Instead, they work via electronic ignition. If this ignition stops working correctly, the burners can’t perform like they are supposed to.

When your gas furnace is functioning correctly, here’s how it should operate:

    • The thermostat tells your furnace to run.
    • Your furnace’s draft inducer fan turns on to bring fresh air into your furnace.
    • The gas valve opens to move gas into the pilot burner.
    • An electronic spark starts the pilot light.
    • The flame sensor tells your furnace that the pilot has been ignited.
    • The gas valve moves gas to the main burners, which are lit by the pilot light.
    • Your furnace then pushes warm air into your house via ductwork.

If something malfunctions during this procedure, your furnace will turn off for safety concerns. Or it might turn off a few minutes into heating because it’s too warm.

A number of of these problems can be resolved on their own, but others require professional assistance.

Here are some of the main 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 informs your furnace when gas is ignited. If the sensor is dirty or damaged, it might work intermittently or not at all. Even if the sensor is operating as normal, incorrect positioning leaves it unable to recognize the flame at all. While you can try troubleshooting and cleaning this sensor by yourself, calling an expert like Service Experts Heating, Air Conditioning & Plumbing will guarantee the problem is taken care of swiftly and correctly.

2. Furnace is Too Hot

Your furnace contains built-in safety features that force a shutdown if it gets too hot. One of the most typical causes is a clogged filter. We suggest inspecting your air filter every month. If you can’t see light through it, change it.

3. Thermostat Isn’t Working Right

Your thermostat directs your furnace when it needs to heat your home. When it’s not functioning normally, your furnace will have trouble keeping your home warm. This can be a battery or electrical problem, depending on what type of thermostat you have. We suggest opening your owner’s manual or manufacturer’s website for necessary troubleshooting details. If you still can’t get yours working, reach out to our Experts at . We’ll discover the problem promptly and can replace your thermostat, if needed.

A number of these issues, including a dirty flame sensor or an overheated furnace, are due to a lack of routine furnace maintenance. It’s highly beneficial to have this service completed once a year, because it could help prevent breakdowns, boost your furnace’s energy efficiency and may even make it survive longer.
