Fixing a Furnace That Wont Stay Lit

A faulty furnace is exhausting to put up with. There are multiple reasons this may happen, but one of the most frequent is an issue with the burners or relevant systems.

Newer systems don’t require pilot lights to keep the furnace ignited. Instead, they work via electronic ignition. If this ignition is damaged, the burners will not perform like they do normally.

When your gas furnace is functioning properly, here’s how it should work:

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

If something fails during this sequence, your furnace will deactivate for safety concerns. Or it might stop a few minutes into heating because it’s overheating.

A number of of these malfunctions can be resolved on their own, but others need professional servicing. When you want the top furnace repair in Columbus, call our heat Experts at 614-334-3192.

Here are a few of the most common reasons why your furnace isn’t staying lit and what to do about 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 damaged, it may work erratically or not at all. Even if the sensor is running as normal, incorrect positioning leaves it unable to recognize the flame at all. While you can try troubleshooting and cleaning this sensor right away, trusting a professional like Service Experts Heating & Air Conditioning will ensure the problem is taken care of swiftly and correctly.

2. Furnace is Too Hot

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

3. Thermostat Isn’t Working Right

Your thermostat informs your furnace when it should heat your home. When it’s not working normally, your furnace will require more energy to keep your home warm. This can be a battery or electrical problem, depending on what kind of thermostat you use. We recommend reviewing your owner’s manual or manufacturer’s website for required troubleshooting info. If you still can’t get yours working, reach out to our Experts at 614-334-3192. We’ll find the cause swiftly and can replace your thermostat, if needed.

Several of these issues, such as a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s crucial to have this service completed every year, because it might help minimize breakdowns, boost your furnace’s energy efficiency and can even make it survive longer.
