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

A broken furnace is a hassle to put up with. There are lots of reasons this may happen, but one of the most likely is something wrong with the burners or associated parts.

Newer models don’t require pilot lights to keep the furnace going. Instead, they work via electronic ignition. If this ignition is damaged, the burners can’t work like they should.

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

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

If something fails during this process, your furnace will shut down for safety purposes. Or it might shut down 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 servicing.

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

1. Malfunctioning Flame Sensor

Your furnace’s flame sensor is a safety system that tells your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it could work inconsistently or not at all. Even if the sensor is functioning as normal, incorrect positioning leaves it unable to identify the flame entirely. While you can attempt troubleshooting and cleaning this sensor right away, trusting a professional like McElroy Service Experts will ensure the problem is handled quickly and correctly.

2. Overheated Furnace

Your furnace contains built-in safety procedures that deactivates your furnace if it gets especially hot. One of the most common causes is a clogged filter. We suggest inspecting your air filter every month. If you can’t see light through it, replace it.

3. Thermostat is Malfunctioning

Your thermostat commands your furnace when it should heat your house. When it’s not working correctly, your furnace will struggle to keep your residence warm. This can be a battery or electrical malfunction, depending on what kind of thermostat you use. We suggest referring to your owner’s manual or manufacturer’s website for useful troubleshooting details. If you still can’t get yours working, reach out to our Experts at 308-210-4398. We’ll discover the cause promptly and can replace your thermostat, if that is required.

Several of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of proper furnace maintenance. It’s crucial to have this service completed every year, because it can help stop breakdowns, improve your furnace’s energy efficiency and could even make it live longer.
