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

A broken furnace is tedious to deal with. There are lots of reasons this can happen, but one of the most common is a problem with the burners or associated components.

Newer furnaces don’t use pilot lights to keep the furnace ignited. Instead, they use electronic ignition. If this ignition stops working correctly, the burners can’t perform like they do normally.

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

  • The thermostat tells your furnace to activate.
  • Your furnace’s draft inducer fan turns on to draw fresh air through 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 has been ignited.
  • The gas valve sends gas to the central burners, which are lit by the pilot light.
  • Your furnace then sends warm air into your home via ductwork.

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

Several of these issues can be fixed on their own, but others need professional assistance.

Here are several of the main reasons why your furnace isn’t staying lit and what to do moving forward.

1. Malfunctioning Flame Sensor

Your furnace’s flame sensor is a safety system that informs your furnace when gas is ignited. If the sensor is dirty or damaged, it could work intermittently or not at all. Even if the sensor is functioning as normal, incorrect positioning leaves it unable to sense the flame at all. While you may attempt troubleshooting and cleaning this sensor by yourself, trusting an expert like Bryant Heating & Cooling Service Experts will ensure the problem is resolved swiftly and correctly.

2. Overheated Furnace

Your furnace uses built-in safety features that shut it off if it gets too hot. One of the most common causes is a dirty filter. We encourage evaluating your air filter monthly. If you can’t see light through it, replace it.

3. Thermostat Isn’t Working Right

Your thermostat directs your furnace when it should heat your house. When it’s not operating correctly, your furnace will have trouble keeping your home warm. This can be a battery or electrical issue, depending on what model of thermostat you use. We recommend opening your owner’s manual or manufacturer’s website for useful troubleshooting procedures. If you still can’t get yours working, call our Experts at 226-773-3357. We’ll identify the cause swiftly and can replace your thermostat, if needed.

A number of these issues, such as a dirty flame sensor or an overheated furnace, are due to a lack of consistent furnace maintenance. It’s important to have this service done every year, because it can help minimize breakdowns, boost your furnace’s energy efficiency and could even make it last longer.
