3 Explanations Why Your Furnace Isn’t Staying Lit and How to Solve It

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

Newer models don’t use pilot lights to keep the furnace going. Instead, they use electronic ignition. If this ignition malfunctions, the burners won’t function like they should. 

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

• The thermostat tells your furnace to run. 
• Your furnace’s draft inducer fan starts to bring fresh air toward your furnace. 
• The gas valve opens to send gas into the pilot burner. 
• An electronic spark starts the pilot light. 

• The flame sensor directs your furnace that the pilot is burning. 
• The gas valve moves gas to the central burners, which are lit by the pilot light. 
• Your furnace then moves warm air into your residence via ductwork. 

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

A number of of these issues can be resolved on their own, but others are best handled by professional assistance.

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

1. Dirty 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 malfunctioning, it might work inconsistently or not at all. Even if the sensor is running as normal, poor positioning leaves it unable to identify the flame at all. While you may start troubleshooting and cleaning this sensor right away, hiring an expert like Service Experts Heating & Air Conditioning will make sure the problem is resolved quickly and correctly. 

2. Overheated Furnace 

Your furnace contains built-in safety procedures that shut it off if it gets dangerously hot. One of the most typical causes is a filthy filter. We suggest evaluating your air filter each month. 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 operating properly, your furnace will struggle to keep your house warm. This can be a battery or electrical malfunction, depending on what kind of thermostat you use. We encourage opening your owner’s manual or manufacturer’s website for specific troubleshooting info. If you still can’t get yours working, call our Experts at 954-736-4314. We’ll pinpoint the cause swiftly and can replace your thermostat, if necessary. 

A number 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 once a year, because it can help prevent breakdowns, enhance your furnace’s energy efficiency and may even make it survive longer.
