How to Repair a Furnace That Wont Stay Lit

A broken furnace is exhausting to handle. There are many reasons this might happen, but one of the most likely is an issue with the burners or associated parts.

Newer models don’t count on pilot lights to keep the furnace lit. Instead, they use electronic ignition. If this ignition fails, the burners won’t perform like they are supposed to.

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

  • The thermostat informs your furnace to turn on.
  • Your furnace’s draft inducer fan begins to spin in order to pull 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 has been ignited.
  • The gas valve sends gas to the principal burners, which are lit by the pilot light.
  • Your furnace then pushes warm air throughout your house via ductwork.

If something goes wrong during this procedure, 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 malfunctions can be fixed on their own, but others need professional assistance.

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

1. Dirty Flame Sensor

Your furnace’s flame sensor is a safety component that tells your furnace when gas is ignited. If the sensor is dirty or faulty, it may work erratically or not at all. Even if the sensor is running as normal, incorrect 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 professional like Air Engineers Service Experts will guarantee the problem is taken care of promptly and correctly.

2. Furnace is Too Hot

Your furnace utilizes built-in safety procedures that shut it off if it gets too hot. One of the most frequent causes is a clogged filter. We encourage inspecting your air filter monthly. If you can’t see light through it, replace it.

3. Thermostat is Malfunctioning

Your thermostat commands your furnace when it needs to heat your house. When it’s not functioning properly, your furnace will have trouble keeping your residence warm. This can be a battery or electrical issue, depending on what type of thermostat you use. We suggest checking your owner’s manual or manufacturer’s website for relevant troubleshooting instructions. If you still can’t get yours working, call our Experts at 904-450-5672. We’ll identify the problem right away and can replace your thermostat, if needed.

A number of these issues, including a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s crucial to have this service performed yearly, because it may help minimize breakdowns, improve your furnace’s energy efficiency and might even make it survive longer.
