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

A broken furnace is a hassle to put up with. There are lots of reasons this might happen, but one of the most frequent is a problem with the burners or relevant parts.

Newer furnaces don’t require pilot lights to keep the furnace lit. Instead, they use electronic ignition. If this ignition is damaged, the burners will not perform like they should.

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

    • The thermostat informs your furnace to activate.
    • Your furnace’s draft inducer fan turns on 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 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 pushes warm air into your home via ductwork.

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

Several of these malfunctions can be repaired on their own, but others are best handled by professional help.

Here are a number of the most common reasons why your heater isn’t staying lit and what to do to fix it.

1. Dirty 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 faulty, it could work erratically or not at all. Even if the sensor is operating normally, poor positioning leaves it unable to identify the flame at all. While you can attempt troubleshooting and cleaning this sensor on your own, calling a professional like Service Experts Heating, Air Conditioning & Plumbing will make sure the problem is taken care of promptly and correctly.

2. Furnace is Too Hot

Your furnace utilizes built-in safety functions that shut it off if it gets especially hot. One of the most common causes is a dirty filter. We suggest checking your air filter each month. If you can’t see light through it, replace it.

3. Thermostat Malfunction

Your thermostat directs your furnace when it should heat your residence. When it’s not functioning properly, your furnace will struggle to keep your home warm. This can be a battery or electrical malfunction, depending on what type of thermostat you have. We recommend reviewing your owner’s manual or manufacturer’s website for required troubleshooting procedures. If you still can’t get yours working, call our Experts at . We’ll identify the cause promptly and can replace your thermostat, if needed.

A number of these issues, like a dirty flame sensor or an overheated furnace, are due to a lack of proper furnace maintenance. It’s crucial to have this service completed every year, because it can help stop breakdowns, enhance your furnace’s energy efficiency and might even make it live longer.
