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

A broken furnace is a hassle to put up with. There are many reasons this may happen, but one of the most common is something wrong with the burners or related systems.

Newer models don’t depend on pilot lights to keep the furnace going. Instead, they use electronic ignition. If this ignition is damaged, the burners will not work like they are supposed to.

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

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

If something fails during this sequence, your furnace will stop for safety concerns. Or it might turn off a few minutes into heating because it’s too warm.

Some of these problems can be resolved on their own, but others need professional help. When you want the finest furnace repair in Jackson, contact our furnace Experts at 601-852-3105. We have experience with all brands and our work is backed by a 100% Satisfaction Guarantee for a year.*

Here are several of the most common reasons why your heating isn’t staying lit and what to do to fix 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 inconsistently or not at all. Even if the sensor is working normally, misaligned positioning leaves it unable to detect the flame at all. While you can try troubleshooting and cleaning this sensor by yourself, hiring a professional like Comfortech Service Experts will guarantee the problem is handled quickly and correctly.

2. Furnace is Too Warm

Your furnace utilizes built-in safety features that force a shutdown if it gets especially hot. One of the most common causes is a dirty filter. We recommend checking your air filter each month. If you can’t see light through it, replace it.

3. Thermostat Malfunction

Your thermostat commands your furnace when it is time to heat your house. When it’s not running normally, 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 encourage checking your owner’s manual or manufacturer’s website for necessary troubleshooting details. If you still can’t get yours working, get in touch with our Experts at 601-852-3105. We’ll identify the issue promptly and can replace your thermostat, if needed.

A number of these issues, including a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s vital to have this service done once a year, because it might help stop breakdowns, increase your furnace’s energy efficiency and might even make it survive longer.
