3 Reasons Why Your Furnace Isnt Staying Lit and How to Repair It

A broken furnace is exhausting to put up with. There are lots of reasons this may happen, but one of the most frequent is something wrong with the burners or associated components.

Newer systems don’t require pilot lights to keep the furnace lit. Instead, they work via electronic ignition. If this ignition malfunctions, the burners can’t function like they do normally.

When your gas furnace is performing properly, here’s how it should operate:

  • The thermostat tells your furnace to run.
  • Your furnace’s draft inducer fan begins to spin in order to bring fresh air through your furnace.
  • The gas valve opens to send gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor informs your furnace that the pilot has been lit.
  • The gas valve transports gas to the principal burners, which are lit by the pilot light.
  • Your furnace then distributes warm air throughout your house via ductwork.

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

A number of of these problems can be handled on their own, but others require professional assistance.

Here are several of the main 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 informs your furnace when gas is ignited. If the sensor is dirty or damaged, it might work intermittently or not at all. Even if the sensor is functioning normally, misaligned positioning leaves it unable to identify the flame at all. While you could try troubleshooting and cleaning this sensor on your own, hiring a pro like Strand Brothers Service Experts will ensure the problem is resolved swiftly and correctly.

2. Furnace is Too Warm

Your furnace contains built-in safety functions that force a shutdown if it gets dangerously hot. One of the most frequent causes is a filthy filter. We encourage inspecting your air filter monthly. If you can’t see light through it, replace it.

3. Thermostat Malfunction

Your thermostat tells your furnace when it needs to heat your residence. When it’s not running like it should, your furnace will struggle to keep your residence warm. This can be a battery or electrical malfunction, depending on what type of thermostat you use. We encourage reviewing your owner’s manual or manufacturer’s website for required troubleshooting details. If you still can’t get yours working, get in touch with our Experts at 512-592-3072 . We’ll discover the cause right away and can replace your thermostat, if necessary.

Some of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of consistent furnace maintenance. It’s highly beneficial to have this service performed once a year, because it could help stop breakdowns, boost your furnace’s energy efficiency and can even make it survive longer.
