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

A damaged furnace is tedious to deal with. There are several reasons this might happen, but one of the most common is something wrong with the burners or relevant systems.

Newer models don’t require pilot lights to keep the furnace ignited. Instead, they use electronic ignition. If this ignition is damaged, the burners won’t work like they are supposed to.

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

  • The thermostat tells your furnace to turn on.
  • Your furnace’s draft inducer fan starts to pull fresh air toward 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 is burning.
  • The gas valve sends gas to the central burners, which are lit by the pilot light.
  • Your furnace then pushes warm air throughout your house via ductwork.

If something breaks down during this process, your furnace will stop for safety reasons. Or it might stop a few minutes into heating because it’s too warm.

A number of of these malfunctions can be resolved on their own, but others require professional help. When you need the fastest furnace repair in Fort Worth, call our heat Experts at 817-668-6689. We work with all brands and our service is backed by a 100% Satisfaction Guarantee for a year.*

Here are several of the typical 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 notifies your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it may work inconsistently or not at all. Even if the sensor is operating as normal, misaligned positioning leaves it unable to recognize the flame at all. While you can try troubleshooting and cleaning this sensor by yourself, calling a professional like Stark Services will make sure the problem is resolved promptly and correctly.

2. Furnace is Too Warm

Your furnace has built-in safety procedures that force a shutdown if it gets too hot. One of the most frequent causes is a dirty filter. We recommend checking your air filter monthly. If you can’t see light through it, replace it.

3. Thermostat is Malfunctioning

Your thermostat commands your furnace when it should heat your home. When it’s not working properly, your furnace will have trouble keeping your home 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 relevant troubleshooting procedures. If you still can’t get yours working, reach out to our Experts at 817-668-6689. We’ll pinpoint the problem quickly and can replace your thermostat, if that is required.

Several of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of proper furnace maintenance. It’s important to have this service completed once a year, because it can help stop breakdowns, improve your furnace’s energy efficiency and could even make it survive longer.
