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

A damaged furnace is exhausting to put up with. There are multiple reasons this may happen, but one of the most common is a problem with the burners or related systems.

Newer models don’t require pilot lights to keep the furnace ignited. Instead, they use electronic ignition. If this ignition stops working correctly, the burners won’t work like they should.

When your gas furnace is performing properly, here’s how it should operate:

  • The thermostat directs your furnace to activate.
  • 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 tells your furnace that the pilot is burning.
  • The gas valve sends gas to the central burners, which are lit by the pilot light.
  • Your furnace then moves warm air throughout your house via ductwork.

If something breaks down during this process, your furnace will shut down for safety reasons. Or it might turn off a few minutes into heating because it’s too warm.

A number of of these problems can be repaired on their own, but others require professional assistance.

Here are some of the typical 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 system that notifies 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 operating as normal, misaligned positioning leaves it unable to detect the flame at all. While you could start troubleshooting and cleaning this sensor on your own, contacting an expert like Service Experts Heating & Air Conditioning will ensure the problem is fixed promptly and correctly.

2. Overheated Furnace

Your furnace uses built-in safety procedures that force a shutdown if it gets especially hot. One of the most common causes is a clogged filter. We recommend checking your air filter monthly. If you can’t see light through it, change it.

3. Thermostat is Malfunctioning

Your thermostat commands your furnace when it needs to heat your residence. When it’s not working like it should, your furnace will struggle to keep your home warm. This can be a battery or electrical malfunction, depending on what model of thermostat you own. We recommend opening your owner’s manual or manufacturer’s website for specific troubleshooting instructions. If you still can’t get yours working, get in touch with our Experts at 318-588-8163. We’ll pinpoint the issue promptly and can replace your thermostat, if that is required.

Some of these issues, including a dirty flame sensor or an overheated furnace, are due to a lack of proper furnace maintenance. It’s extremely helpful to have this service performed yearly, because it could help reduce breakdowns, increase your furnace’s energy efficiency and could even make it last longer.
