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

A malfunctioning furnace is exhausting to put up with. There are lots of reasons this might happen, but one of the most common is something wrong with the burners or associated parts. 

Newer furnaces don’t count on pilot lights to keep the furnace going. Instead, they work via electronic ignition. If this ignition stops working correctly, the burners can’t work like they do normally. 

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

• The thermostat directs your furnace to activate. 
• Your furnace’s draft inducer fan starts to pull fresh air through your furnace. 
• The gas valve opens to direct gas into the pilot burner. 
• An electronic spark ignites the pilot light. 

• The flame sensor tells your furnace that the pilot is burning. 
• The gas valve transports gas to the principal burners, which are lit by the pilot light. 
• Your furnace then provides warm air across your house via ductwork. 

If something goes wrong during this process, your furnace will turn off for safety reasons. Or it might turn off a few minutes into heating because it’s getting too hot. 

Some of these problems can be handled on their own, but others need professional help. When you are looking for the finest furnace repair in Fort Lauderdale, contact our furnace Experts at 954-736-4314. We repair all brands and our work is ensured by a 100% Satisfaction Guarantee for a year.* 

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 malfunctioning, it could work erratically or not at all. Even if the sensor is operating normally, incorrect positioning leaves it unable to sense the flame to begin with. While you could start troubleshooting and cleaning this sensor by yourself, contacting a pro like Service Experts Heating & Air Conditioning will make sure the problem is taken care of quickly and correctly. 

2. Overheated Furnace 

Your furnace contains built-in safety functions that shut it off if it gets dangerously hot. One of the most typical causes is a dirty filter. We recommend checking your air filter every month. If you can’t see light through it, change it. 

3. Thermostat Malfunction 

Your thermostat tells your furnace when it is time to heat your home. When it’s not functioning properly, your furnace will require more energy to keep your house warm. This can be a battery or electrical malfunction, depending on what type of thermostat you use. We recommend referring to your owner’s manual or manufacturer’s website for required troubleshooting info. If you still can’t get yours working, reach out to our Experts at 954-736-4314. We’ll uncover the cause swiftly and can replace your thermostat, if necessary. 

Some of these issues, including a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s extremely helpful to have this service done annually, because it might help reduce breakdowns, improve your furnace’s energy efficiency and might even make it survive longer.
