3 Explanations Why Your Furnace Isnt Staying Lit and How to Fix It

A malfunctioning furnace is exhausting to deal with. There are multiple reasons this may happen, but one of the most likely is a problem with the burners or associated parts.

Newer furnaces don’t depend on pilot lights to keep the furnace going. Instead, they utilize electronic ignition. If this ignition malfunctions, the burners will not perform like they are supposed to.

When your gas furnace is functioning normally, here’s how it should work:

  • The thermostat tells your furnace to run.
  • Your furnace’s draft inducer fan begins to spin in order to draw 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 informs your furnace that the pilot has been ignited.
  • The gas valve sends gas to the central burners, which are lit by the pilot light.
  • Your furnace then moves warm air throughout your residence via ductwork.

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

A number of of these issues can be handled on their own, but others need professional help. When you want the top furnace repair in Ocala, reach out to our heat Experts at 352-414-4006. We have experience with all brands and our work is supported by a 100% Satisfaction Guarantee for a year.*

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

1. Malfunctioning 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 malfunctioning, it might work inconsistently or not at all. Even if the sensor is functioning as normal, poor positioning leaves it unable to recognize the flame to begin with. While you could try troubleshooting and cleaning this sensor on your own, calling a professional like Service Experts Heating & Air Conditioning will ensure the problem is resolved quickly and correctly.

2. Overheated Furnace

Your furnace has built-in safety features that force a shutdown if it gets dangerously hot. One of the most frequent causes is a filthy filter. We encourage inspecting your air filter monthly. If you can’t see light through it, change it.

3. Thermostat Malfunction

Your thermostat tells your furnace when it needs to heat your residence. When it’s not running properly, 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 have. We suggest reviewing your owner’s manual or manufacturer’s website for required troubleshooting instructions. If you still can’t get yours working, contact our Experts at 352-414-4006. We’ll find the problem swiftly and can replace your thermostat, if necessary.

Several of these issues, like a dirty flame sensor or an overheated furnace, are a result of a lack of routine furnace maintenance. It’s vital to have this service completed annually, because it might help stop breakdowns, improve your furnace’s energy efficiency and may even make it survive longer.
