Fixing a Furnace That Wont Stay Lit

A broken furnace is a hassle to handle. There are many reasons this might happen, but one of the most likely is something wrong with the burners or relevant parts.

Newer systems don’t require pilot lights to keep the furnace going. Instead, they utilize electronic ignition. If this ignition fails, the burners can’t perform like they do normally.

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

  • The thermostat informs your furnace to activate.
  • Your furnace’s draft inducer fan begins to spin in order to bring fresh air toward your furnace.
  • The gas valve opens to direct gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor directs your furnace that the pilot has been ignited.
  • The gas valve transports 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 procedure, your furnace will stop for safety concerns. Or it might shut down a few minutes into heating because it’s getting too hot.

Some of these problems can be resolved on their own, but others are best handled by professional servicing.

Here are several of the top 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 feature that notifies your furnace when gas is ignited. If the sensor is dirty or faulty, it could work intermittently or not at all. Even if the sensor is operating as normal, incorrect positioning leaves it unable to detect the flame to begin with. While you may try troubleshooting and cleaning this sensor by yourself, hiring an expert like Service Experts Heating & Air Conditioning will ensure the problem is fixed quickly and correctly.

2. Overheated Furnace

Your furnace utilizes built-in safety functions that force a shutdown if it gets too hot. One of the most common causes is a filthy filter. We suggest inspecting your air filter every month. If you can’t see light through it, change it.

3. Thermostat Isn’t Working Right

Your thermostat tells your furnace when it is time to heat your home. When it’s not functioning correctly, your furnace will have trouble keeping your house warm. This can be a battery or electrical problem, depending on what kind of thermostat you own. We recommend opening your owner’s manual or manufacturer’s website for needed troubleshooting info. If you still can’t get yours working, get in touch with our Experts at 303-647-5749. We’ll uncover the cause swiftly and can replace your thermostat, if necessary.

Some of these issues, such as a dirty flame sensor or an overheated furnace, are due to a lack of routine furnace maintenance. It’s highly beneficial to have this service performed every year, because it may help stop breakdowns, improve your furnace’s energy efficiency and can even make it live longer.
