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

A malfunctioning furnace is exhausting to deal with. There are many reasons this can happen, but one of the most common is something wrong with the burners or related components.

Newer systems don’t depend on pilot lights to keep the furnace ignited. Instead, they utilize electronic ignition. If this ignition stops working correctly, the burners won’t work like they are supposed to.

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

  • The thermostat directs your furnace to turn on.
  • Your furnace’s draft inducer fan begins to spin in order to bring fresh air toward your furnace.
  • The gas valve opens to move gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor tells your furnace that the pilot has been ignited.
  • The gas valve transports gas to the primary burners, which are lit by the pilot light.
  • Your furnace then distributes warm air across your house via ductwork.

If something goes wrong during this sequence, your furnace will shut down for safety purposes. Or it might stop a few minutes into heating because it’s getting too hot.

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

Here are several of the top reasons why your heater 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 could work inconsistently or not at all. Even if the sensor is functioning as normal, poor positioning leaves it unable to identify the flame entirely. While you can start troubleshooting and cleaning this sensor by yourself, trusting an expert like Fras-Air/General Service Experts will ensure the problem is fixed swiftly and correctly.

2. Furnace is Too Warm

Your furnace has built-in safety features that deactivates your furnace if it gets especially hot. One of the most typical causes is a dirty filter. We encourage checking your air filter each month. If you can’t see light through it, swap it out.

3. Thermostat Isn’t Working Right

Your thermostat informs your furnace when it should heat your home. When it’s not operating as it’s supposed to, your furnace will struggle to keep your home warm. This can be a battery or electrical issue, depending on what kind of thermostat you have. We suggest reviewing your owner’s manual or manufacturer’s website for useful troubleshooting info. If you still can’t get yours working, reach out to our Experts at 908-448-2154. We’ll pinpoint the problem swiftly and can replace your thermostat, if that is required.

A number of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of consistent furnace maintenance. It’s crucial to have this service completed every year, because it could help stop breakdowns, increase your furnace’s energy efficiency and might even make it survive longer.
