How to Fix a Furnace That Wont Stay Lit

A broken furnace is a hassle to handle. There are multiple reasons this might happen, but one of the most common is an issue with the burners or relevant systems.

Newer models don’t rely on pilot lights to keep the furnace going. Instead, they utilize electronic ignition. If this ignition is damaged, the burners can’t perform like they do normally.

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

  • The thermostat directs your furnace to activate.
  • Your furnace’s draft inducer fan turns on to draw fresh air into your furnace.
  • The gas valve opens to move gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor informs your furnace that the pilot has been ignited.
  • The gas valve transports gas to the principal burners, which are lit by the pilot light.
  • Your furnace then distributes warm air throughout your house via ductwork.

If something malfunctions during this sequence, your furnace will stop for safety purposes. Or it might shut down a few minutes into heating because it’s getting too hot.

A number of of these problems can be repaired on their own, but others require professional servicing. When you want the top furnace repair in Dayton, contact our heat Experts at 937-503-7896. We work with all brands and our work is supported by a 100% Satisfaction Guarantee for a year.*

Here are several of the top reasons why your heater isn’t staying lit and what to do to fix 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 malfunctioning, it may work erratically or not at all. Even if the sensor is functioning normally, misaligned positioning leaves it unable to recognize the flame to begin with. While you can attempt troubleshooting and cleaning this sensor on your own, contacting a pro like Stevenson Service Experts will ensure the problem is fixed quickly and correctly.

2. Overheated Furnace

Your furnace utilizes built-in safety procedures that force a shutdown if it gets especially hot. One of the most typical causes is a filthy filter. We recommend inspecting your air filter monthly. If you can’t see light through it, swap it out.

3. Thermostat is Malfunctioning

Your thermostat informs your furnace when it should heat your residence. When it’s not working like it should, your furnace will require more energy to keep your house warm. This can be a battery or electrical issue, depending on what model of thermostat you use. We recommend opening your owner’s manual or manufacturer’s website for useful troubleshooting information. If you still can’t get yours working, get in touch with our Experts at 937-503-7896. We’ll uncover the cause promptly and can replace your thermostat, if necessary.

Several of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of routine furnace maintenance. It’s highly beneficial to have this service performed once a year, because it can help stop breakdowns, enhance your furnace’s energy efficiency and could even make it last longer.
