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

A malfunctioning furnace is a hassle to handle. There are lots of reasons this can happen, but one of the most likely is a problem with the burners or relevant components.

Newer systems don’t rely on pilot lights to keep the furnace going. Instead, they use electronic ignition. If this ignition malfunctions, the burners will not function like they should.

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 begins to spin in order to bring fresh air through your furnace.
  • The gas valve opens to move gas into the pilot burner.
  • An electronic spark lights the pilot light.
  • The flame sensor informs your furnace that the pilot is burning.
  • The gas valve sends gas to the primary burners, which are lit by the pilot light.
  • Your furnace then provides warm air into your house via ductwork.

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

Several of these issues can be resolved on their own, but others are best handled by professional help. When you need the top furnace repair in Mobile, reach out to our furnace Experts at 251-202-7503. We repair all brands and our work is backed by a 100% Satisfaction Guarantee for a year.*

Here are some of the typical 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 malfunctioning, it may work erratically or not at all. Even if the sensor is working like it should, misaligned positioning leaves it unable to detect the flame to begin with. While you could attempt troubleshooting and cleaning this sensor right away, hiring a professional like Climate Control Service Experts will ensure the problem is resolved swiftly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety functions that shut it off if it gets dangerously hot. One of the most frequent causes is a filthy filter. We recommend reviewing your air filter each month. If you can’t see light through it, swap it out.

3. Thermostat Malfunction

Your thermostat informs your furnace when it should heat your home. When it’s not running like it should, your furnace will require more energy to keep your residence warm. This can be a battery or electrical malfunction, depending on what type of thermostat you have. We encourage reviewing your owner’s manual or manufacturer’s website for required troubleshooting information. If you still can’t get yours working, contact our Experts at 251-202-7503. We’ll uncover the issue right away and can replace your thermostat, if that is required.

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