Fixing a Furnace That Wont Stay Lit

A broken furnace is a hassle to put up with. There are multiple reasons this can happen, but one of the most common is a problem with the burners or related parts.

Newer models don’t require pilot lights to keep the furnace ignited. Instead, they utilize electronic ignition. If this ignition is damaged, the burners can’t work like they are supposed to.

When your gas furnace is functioning correctly, here’s how it should operate:

  • The thermostat directs your furnace to run.
  • Your furnace’s draft inducer fan turns on to draw fresh air toward your furnace.
  • The gas valve opens to direct gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor tells 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 across your residence via ductwork.

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

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

Here are a few of the typical reasons why your heating isn’t staying lit and what to do moving forward.

1. Faulty 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 faulty, it may work intermittently or not at all. Even if the sensor is running normally, misaligned positioning leaves it unable to identify the flame entirely. While you could start troubleshooting and cleaning this sensor on your own, calling a pro like All American Air Service Experts will make sure the problem is resolved swiftly 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 typical 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 working like it should, your furnace will struggle to keep your house warm. This can be a battery or electrical malfunction, depending on what kind of thermostat you have. We encourage opening your owner’s manual or manufacturer’s website for relevant troubleshooting instructions. If you still can’t get yours working, get in touch with our Experts at 386-310-2061. We’ll identify the problem right away and can replace your thermostat, if needed.

Some of these issues, like a dirty flame sensor or an overheated furnace, are caused by a lack of consistent furnace maintenance. It’s crucial to have this service completed every year, because it might help reduce breakdowns, increase your furnace’s energy efficiency and could even make it live longer.
