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

A broken furnace is tedious to handle. There are several reasons this may happen, but one of the most common is an issue with the burners or associated parts.

Newer furnaces don’t rely on pilot lights to keep the furnace going. Instead, they utilize electronic ignition. If this ignition is damaged, the burners will not function like they are supposed to.

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

  • The thermostat directs your furnace to run.
  • Your furnace’s draft inducer fan starts 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 is burning.
  • The gas valve directs gas to the main burners, which are lit by the pilot light.
  • Your furnace then transports warm air across your home via ductwork.

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

Several of these issues can be repaired on their own, but others are best handled by professional assistance.

Here are a few of the main reasons why your heating isn’t staying lit and what to do about it.

1. Dirty Flame Sensor

Your furnace’s flame sensor is a safety feature that tells your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it may work intermittently 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 try troubleshooting and cleaning this sensor on your own, contacting a professional like Comfort Masters Service Experts will guarantee the problem is handled promptly and correctly.

2. Overheated Furnace

Your furnace contains built-in safety features that shut it off if it gets too hot. One of the most frequent causes is a clogged filter. We encourage evaluating your air filter monthly. If you can’t see light through it, change it.

3. Thermostat Malfunction

Your thermostat tells your furnace when it should heat your residence. When it’s not working correctly, your furnace will have trouble keeping your home warm. This can be a battery or electrical issue, depending on what type of thermostat you use. We encourage referring to your owner’s manual or manufacturer’s website for relevant troubleshooting information. If you still can’t get yours working, call our Experts at 847-250-6729. We’ll discover the cause right away and can replace your thermostat, if that is required.

Some of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of proper furnace maintenance. It’s highly beneficial to have this service performed every year, because it can help minimize breakdowns, increase your furnace’s energy efficiency and might even make it live longer.
