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

A damaged furnace is exhausting to deal with. There are lots of reasons this can happen, but one of the most frequent is an issue with the burners or related components. 

Newer systems don’t count on pilot lights to keep the furnace ignited. Instead, they utilize electronic ignition. If this ignition malfunctions, the burners will not function like they are supposed to. 

When your gas furnace is running normally, here’s how it should run: 

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

• The flame sensor tells your furnace that the pilot is burning. 
• The gas valve sends 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 breaks down during this sequence, your furnace will turn off for safety concerns. Or it might stop a few minutes into heating because it’s too warm. 

Some of these malfunctions can be resolved on their own, but others require professional assistance.

Here are several of the most common 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 component that informs your furnace when gas is ignited. If the sensor is dirty or faulty, it might work intermittently or not at all. Even if the sensor is operating normally, incorrect positioning leaves it unable to detect the flame at all. While you could try troubleshooting and cleaning this sensor on your own, contacting a professional like Service Experts Heating & Air Conditioning will guarantee the problem is resolved promptly and correctly. 

2. Furnace is Too Hot 

Your furnace utilizes built-in safety features that deactivates your furnace if it gets especially hot. One of the most common causes is a dirty filter. We encourage checking your air filter every month. If you can’t see light through it, swap it out. 

3. Thermostat is Malfunctioning 

Your thermostat informs your furnace when it is time to heat your home. When it’s not running correctly, your furnace will struggle to keep your residence warm. This can be a battery or electrical issue, depending on what type of thermostat you own. We recommend checking your owner’s manual or manufacturer’s website for needed troubleshooting procedures. If you still can’t get yours working, call our Experts at 954-736-4314. We’ll discover the cause right away and can replace your thermostat, if needed. 

Some of these issues, like a dirty flame sensor or an overheated furnace, are a result of a lack of routine furnace maintenance. It’s highly beneficial to have this service completed once a year, because it can help prevent breakdowns, improve your furnace’s energy efficiency and could even make it live longer.
