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

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

Newer systems don’t count on pilot lights to keep the furnace going. Instead, they utilize electronic ignition. If this ignition malfunctions, the burners will not perform like they do normally.

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

  • The thermostat tells your furnace to run.
  • Your furnace’s draft inducer fan begins to spin in order to bring fresh air into your furnace.
  • The gas valve opens to send gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor tells your furnace that the pilot has been lit.
  • The gas valve moves gas to the central burners, which are lit by the pilot light.
  • Your furnace then transports warm air into your house via ductwork.

If something fails during this sequence, your furnace will turn off for safety purposes. Or it might turn off a few minutes into heating because it’s too warm.

A number of of these problems can be resolved on their own, but others require professional servicing.

Here are a few of the most common reasons why your heating 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 faulty, it might work intermittently or not at all. Even if the sensor is functioning like it should, misaligned positioning leaves it unable to sense the flame at all. While you could try troubleshooting and cleaning this sensor by yourself, hiring a pro like Church Services will make sure the problem is fixed promptly and correctly.

2. Furnace is Too Warm

Your furnace has built-in safety functions that shut it off if it gets especially hot. One of the most typical causes is a filthy filter. We suggest reviewing your air filter each month. If you can’t see light through it, swap it out.

3. Thermostat is Malfunctioning

Your thermostat commands your furnace when it needs to heat your house. When it’s not operating like it should, your furnace will struggle to keep your house warm. This can be a battery or electrical issue, depending on what type of thermostat you have. We recommend referring to your owner’s manual or manufacturer’s website for necessary troubleshooting instructions. If you still can’t get yours working, contact our Experts at 713-396-3760. We’ll pinpoint the cause swiftly and can replace your thermostat, if necessary.

A number of these issues, such as a dirty flame sensor or an overheated furnace, are caused by a lack of consistent furnace maintenance. It’s highly beneficial to have this service performed every year, because it could help minimize breakdowns, improve your furnace’s energy efficiency and might even make it last longer.
