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

A faulty furnace is exhausting to put up with. There are several reasons this may happen, but one of the most frequent is something wrong with the burners or relevant systems.

Newer systems don’t rely on pilot lights to keep the furnace ignited. Instead, they utilize electronic ignition. If this ignition malfunctions, the burners won’t function like they are supposed to.

When your gas furnace is running normally, here’s how it should run:

  • The thermostat informs your furnace to turn on.
  • Your furnace’s draft inducer fan turns on to draw fresh air through your furnace.
  • The gas valve opens to direct gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor tells your furnace that the pilot is burning.
  • The gas valve directs gas to the primary burners, which are lit by the pilot light.
  • Your furnace then provides warm air into your home via ductwork.

If something malfunctions during this procedure, your furnace will turn off for safety concerns. Or it might stop a few minutes into heating because it’s getting too hot.

Several of these problems can be resolved on their own, but others require professional assistance.

Here are a few of the most common reasons why your heating 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 tells your furnace when gas is ignited. If the sensor is dirty or damaged, it may work inconsistently or not at all. Even if the sensor is working as normal, poor positioning leaves it unable to recognize the flame entirely. While you could start troubleshooting and cleaning this sensor right away, calling an expert like Service Experts Heating & Air Conditioning will ensure the problem is resolved promptly and correctly.

2. Overheated Furnace

Your furnace contains built-in safety features that shut it off if it gets dangerously hot. One of the most common causes is a clogged filter. We suggest inspecting your air filter each month. If you can’t see light through it, change it.

3. Thermostat Malfunction

Your thermostat tells your furnace when it needs to heat your house. When it’s not running like it should, your furnace will have trouble keeping your home warm. This can be a battery or electrical malfunction, depending on what kind of thermostat you have. We recommend checking your owner’s manual or manufacturer’s website for necessary troubleshooting information. If you still can’t get yours working, get in touch with our Experts at 440-252-1375. We’ll discover the problem promptly and can replace your thermostat, if needed.

Some of these issues, like 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 completed every year, because it could help prevent breakdowns, increase your furnace’s energy efficiency and may even make it live longer.
