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

A malfunctioning furnace is a hassle to put up with. There are many reasons this can happen, but one of the most frequent 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 malfunctions, the burners won’t work like they should.

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

  • The thermostat directs your furnace to activate.
  • Your furnace’s draft inducer fan begins to spin in order to bring fresh air into your furnace.
  • The gas valve opens to direct gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor directs your furnace that the pilot is burning.
  • The gas valve moves gas to the primary burners, which are lit by the pilot light.
  • Your furnace then distributes warm air into your house via ductwork.

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

Some of these problems can be fixed on their own, but others are best handled by professional assistance.

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

1. Malfunctioning 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 damaged, it might work intermittently or not at all. Even if the sensor is running as normal, poor positioning leaves it unable to sense the flame entirely. While you could attempt troubleshooting and cleaning this sensor right away, hiring a pro like Strand Brothers Service Experts will guarantee the problem is taken care of promptly and correctly.

2. Overheated Furnace

Your furnace uses built-in safety features that force a shutdown if it gets too hot. One of the most common causes is a filthy filter. We suggest checking your air filter monthly. 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 home. When it’s not working like it should, your furnace will struggle to keep your house warm. This can be a battery or electrical issue, depending on what model of thermostat you have. We encourage opening your owner’s manual or manufacturer’s website for specific troubleshooting details. If you still can’t get yours working, get in touch with our Experts at 512-596-1257. We’ll pinpoint the cause quickly and can replace your thermostat, if necessary.

A number of these issues, like a dirty flame sensor or an overheated furnace, are caused by a lack of proper furnace maintenance. It’s important to have this service done every year, because it could help prevent breakdowns, enhance your furnace’s energy efficiency and could even make it survive longer.
