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

A damaged furnace is a hassle to handle. There are many reasons this can happen, but one of the most likely is something wrong with the burners or related systems.

Newer furnaces don’t require pilot lights to keep the furnace lit. Instead, they use electronic ignition. If this ignition stops working correctly, the burners will not function like they are supposed to.

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

  • The thermostat informs your furnace to run.
  • Your furnace’s draft inducer fan begins to spin in order to draw fresh air through your furnace.
  • The gas valve opens to send gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor directs your furnace that the pilot has been lit.
  • The gas valve sends gas to the primary burners, which are lit by the pilot light.
  • Your furnace then moves warm air across your residence via ductwork.

If something malfunctions during this sequence, your furnace will deactivate for safety reasons. Or it might stop a few minutes into heating because it’s overheating.

A number of of these issues can be fixed on their own, but others are best handled by professional assistance.

Here are several of the main reasons why your heating isn’t staying lit and what to do moving forward.

1. Dirty Flame Sensor

Your furnace’s flame sensor is a safety feature that informs your furnace when gas is ignited. If the sensor is dirty or faulty, it may work erratically or not at all. Even if the sensor is functioning as normal, misaligned positioning leaves it unable to sense the flame at all. While you may attempt troubleshooting and cleaning this sensor on your own, calling a pro like Komfort Air Service Experts will ensure the problem is resolved swiftly and correctly.

2. Furnace is Too Warm

Your furnace has built-in safety functions that shut it off if it gets dangerously hot. One of the most common causes is a clogged filter. We recommend evaluating your air filter monthly. If you can’t see light through it, swap it out.

3. Thermostat is Malfunctioning

Your thermostat tells your furnace when it is time to heat your house. When it’s not operating normally, your furnace will have trouble keeping your residence warm. This can be a battery or electrical malfunction, depending on what kind of thermostat you use. We recommend reviewing your owner’s manual or manufacturer’s website for necessary troubleshooting procedures. If you still can’t get yours working, reach out to our Experts at 704-705-8135. We’ll pinpoint the cause quickly and can replace your thermostat, if needed.

Several of these issues, such as a dirty flame sensor or an overheated furnace, are caused by a lack of consistent furnace maintenance. It’s extremely helpful to have this service done every year, because it can help reduce breakdowns, improve your furnace’s energy efficiency and can even make it live longer.
