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

A malfunctioning furnace is frustrating to handle. There are lots of reasons this might happen, but one of the most frequent is a problem with the burners or related components.

Newer systems don’t count on pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition fails, the burners won’t function like they do normally.

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

  • The thermostat tells your furnace to activate.
  • Your furnace’s draft inducer fan starts to pull fresh air into your furnace.
  • The gas valve opens to direct 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 moves gas to the main burners, which are lit by the pilot light.
  • Your furnace then pushes warm air into your house via ductwork.

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

Several of these malfunctions can be handled on their own, but others need professional help. When you are looking for the top furnace repair in Raleigh, call our heating Experts at 919-578-4329. We repair all brands and our work is backed by a 100% Satisfaction Guarantee for a year.*

Here are some of the most common reasons why your heater isn’t staying lit and what to do about it.

1. Faulty Flame Sensor

Your furnace’s flame sensor is a safety system that notifies your furnace when gas is ignited. If the sensor is dirty or faulty, it might work inconsistently or not at all. Even if the sensor is operating like it should, incorrect positioning leaves it unable to detect the flame at all. While you could start troubleshooting and cleaning this sensor on your own, calling a professional like Service Experts Heating & Air Conditioning will guarantee the problem is resolved promptly and correctly.

2. Overheated Furnace

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

3. Thermostat is Malfunctioning

Your thermostat tells your furnace when it should heat your house. When it’s not working properly, your furnace will have trouble keeping your house warm. This can be a battery or electrical problem, depending on what type of thermostat you have. We suggest referring to your owner’s manual or manufacturer’s website for relevant troubleshooting instructions. If you still can’t get yours working, get in touch with our Experts at 919-578-4329. We’ll find the problem quickly and can replace your thermostat, if that is required.

Some of these issues, including a dirty flame sensor or an overheated furnace, are due to a lack of proper furnace maintenance. It’s vital to have this service done once a year, because it can help minimize breakdowns, improve your furnace’s energy efficiency and could even make it survive longer.
