Restoring a Furnace That Wont Stay Lit

A malfunctioning furnace is exhausting to handle. There are many reasons this might happen, but one of the most common is a problem with the burners or related parts.

Newer furnaces don’t rely on pilot lights to keep the furnace ignited. Instead, they use electronic ignition. If this ignition malfunctions, the burners can’t perform like they are supposed to.

When your gas furnace is running correctly, here’s how it should work:

  • The thermostat directs your furnace to run.
  • Your furnace’s draft inducer fan begins to spin in order 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 directs your furnace that the pilot is burning.
  • The gas valve transports 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 malfunctions during this procedure, your furnace will shut down for safety reasons. Or it might deactivate a few minutes into heating because it’s overheating.

Several of these malfunctions can be fixed on their own, but others require professional servicing.

Here are several 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 feature that tells your furnace when gas is ignited. If the sensor is dirty or faulty, it might work inconsistently or not at all. Even if the sensor is running normally, misaligned positioning leaves it unable to detect the flame to begin with. While you may try troubleshooting and cleaning this sensor on your own, hiring a pro like Service Experts Heating & Air Conditioning will ensure the problem is fixed quickly and correctly.

2. Furnace is Too Warm

Your furnace utilizes built-in safety procedures that deactivates your furnace if it gets dangerously hot. One of the most common causes is a clogged filter. We recommend reviewing your air filter each month. If you can’t see light through it, replace it.

3. Thermostat Isn’t Working Right

Your thermostat informs your furnace when it needs to heat your house. When it’s not working as it’s supposed to, your furnace will have trouble keeping your residence warm. This can be a battery or electrical malfunction, depending on what type of thermostat you have. We encourage reviewing your owner’s manual or manufacturer’s website for needed troubleshooting instructions. If you still can’t get yours working, contact our Experts at 289-273-2229. We’ll identify the problem promptly and can replace your thermostat, if that is required.

Some of these issues, like a dirty flame sensor or an overheated furnace, are caused by a lack of proper furnace maintenance. It’s crucial to have this service completed once a year, because it can help minimize breakdowns, enhance your furnace’s energy efficiency and may even make it last longer.
