3 Reasons Why Your Furnace Isnt Staying Lit and How to Solve It

A malfunctioning furnace is frustrating to handle. There are many reasons this can happen, but one of the most common is an issue with the burners or related components.

Newer systems don’t count on pilot lights to keep the furnace lit. Instead, they work via electronic ignition. If this ignition malfunctions, the burners will not function like they are supposed to.

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

  • The thermostat directs your furnace to activate.
  • Your furnace’s draft inducer fan turns on to pull fresh air through your furnace.
  • The gas valve opens to direct gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor informs your furnace that the pilot has been lit.
  • The gas valve transports gas to the main burners, which are lit by the pilot light.
  • Your furnace then distributes warm air across your home via ductwork.

If something goes wrong during this process, your furnace will stop for safety concerns. Or it might deactivate a few minutes into heating because it’s overheating.

Some of these problems can be repaired on their own, but others are best handled by professional help. When you want the best furnace repair in Naples, contact our heat Experts at 239-908-6991. We service all brands and our services are ensured by a 100% Satisfaction Guarantee for a year.*

Here are a few of the top reasons why your heating isn’t staying lit and what to do moving forward.

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 damaged, it could work erratically or not at all. Even if the sensor is working normally, misaligned positioning leaves it unable to recognize the flame to begin with. While you may start troubleshooting and cleaning this sensor right away, contacting a professional like Service Experts Heating & Air Conditioning 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 dangerously hot. One of the most frequent causes is a filthy filter. We suggest evaluating your air filter every month. If you can’t see light through it, swap it out.

3. Thermostat Malfunction

Your thermostat directs your furnace when it is time to heat your house. When it’s not functioning like it should, your furnace will require more energy to keep your residence warm. This can be a battery or electrical problem, depending on what type of thermostat you use. We recommend opening your owner’s manual or manufacturer’s website for specific troubleshooting instructions. If you still can’t get yours working, contact our Experts at 239-908-6991. We’ll identify the cause right away and can replace your thermostat, if that is required.

A number of these issues, like 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 once a year, because it might help stop breakdowns, improve your furnace’s energy efficiency and can even make it survive longer.
