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

A faulty furnace is frustrating to deal with. There are several reasons this may happen, but one of the most common is a problem with the burners or relevant components.

Newer systems don’t use pilot lights to keep the furnace lit. Instead, they use electronic ignition. If this ignition stops working correctly, the burners can’t work like they do normally.

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

  • The thermostat informs your furnace to turn on.
  • 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 tells your furnace that the pilot is burning.
  • The gas valve transports gas to the primary burners, which are lit by the pilot light.
  • Your furnace then moves warm air throughout your residence via ductwork.

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

Several of these problems can be resolved on their own, but others need professional servicing.

Here are a number of the most common reasons why your furnace 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 faulty, it could work inconsistently or not at all. Even if the sensor is functioning as normal, incorrect positioning leaves it unable to recognize the flame entirely. While you could start troubleshooting and cleaning this sensor on your own, hiring an expert like Service Experts Heating & Air Conditioning will make sure the problem is fixed quickly and correctly.

2. Furnace is Too Warm

Your furnace has built-in safety features that deactivates your furnace if it gets especially hot. One of the most frequent causes is a clogged filter. We recommend reviewing your air filter each month. If you can’t see light through it, replace it.

3. Thermostat Isn’t Working Right

Your thermostat tells your furnace when it needs to heat your residence. When it’s not working as it’s supposed to, your furnace will have trouble keeping your residence warm. This can be a battery or electrical issue, depending on what type of thermostat you own. We recommend opening your owner’s manual or manufacturer’s website for relevant troubleshooting information. If you still can’t get yours working, contact our Experts at 954-736-4314. We’ll uncover the cause swiftly 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 consistent furnace maintenance. It’s extremely helpful to have this service completed annually, because it could help reduce breakdowns, increase your furnace’s energy efficiency and can even make it survive longer.
