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

A malfunctioning furnace is exhausting to deal with. There are several reasons this can happen, but one of the most common is something wrong with the burners or related components.

Newer systems don’t depend on pilot lights to keep the furnace going. Instead, they utilize electronic ignition. If this ignition malfunctions, the burners can’t work like they should.

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

  • The thermostat tells your furnace to activate.
  • Your furnace’s draft inducer fan turns on 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 informs your furnace that the pilot has been ignited.
  • The gas valve directs gas to the primary burners, which are lit by the pilot light.
  • Your furnace then distributes warm air into your residence via ductwork.

If something breaks down during this procedure, your furnace will stop for safety purposes. Or it might turn off a few minutes into heating because it’s overheating.

Several of these malfunctions can be handled on their own, but others need professional assistance.

Here are a number of the most common 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 informs your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it could work intermittently or not at all. Even if the sensor is functioning like it should, misaligned positioning leaves it unable to recognize the flame to begin with. While you could try troubleshooting and cleaning this sensor right away, trusting a pro like Service Experts Heating & Air Conditioning will ensure the problem is fixed promptly and correctly.

2. Overheated Furnace

Your furnace contains built-in safety procedures that force a shutdown if it gets dangerously hot. One of the most common causes is a clogged filter. We suggest checking your air filter monthly. If you can’t see light through it, change it.

3. Thermostat Malfunction

Your thermostat informs your furnace when it should heat your residence. When it’s not running normally, your furnace will struggle to keep your home warm. This can be a battery or electrical issue, depending on what kind of thermostat you use. We recommend referring to your owner’s manual or manufacturer’s website for required troubleshooting details. If you still can’t get yours working, contact our Experts at (713) 352-7887. We’ll discover the cause swiftly and can replace your thermostat, if needed.

Several of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of consistent furnace maintenance. It’s crucial to have this service completed annually, because it could help minimize breakdowns, improve your furnace’s energy efficiency and may even make it survive longer.
