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

A faulty furnace is a hassle to put up with. There are several reasons this might happen, but one of the most likely is something wrong with the burners or related parts. 

Newer models don’t rely on pilot lights to keep the furnace going. Instead, they use electronic ignition. If this ignition is damaged, the burners can’t work like they are supposed to. 

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

• The thermostat informs your furnace to activate. 
• Your furnace’s draft inducer fan starts to bring fresh air toward your furnace. 
• The gas valve opens to direct 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 principal burners, which are lit by the pilot light. 
• Your furnace then transports warm air into your house via ductwork. 

If something malfunctions during this sequence, your furnace will deactivate for safety concerns. Or it might deactivate a few minutes into heating because it’s getting too hot. 

A number of of these problems can be repaired on their own, but others need professional servicing.

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

1. Dirty Flame Sensor 

Your furnace’s flame sensor is a safety component that tells 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 running like it should, incorrect positioning leaves it unable to sense the flame to begin with. While you could try troubleshooting and cleaning this sensor on your own, hiring a pro like Service Experts Heating & Air Conditioning will guarantee the problem is taken care of swiftly and correctly. 

2. Overheated Furnace 

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

3. Thermostat Malfunction 

Your thermostat informs your furnace when it is time to heat your home. When it’s not working normally, your furnace will have trouble keeping your home warm. This can be a battery or electrical problem, depending on what type of thermostat you have. We encourage opening your owner’s manual or manufacturer’s website for needed troubleshooting info. If you still can’t get yours working, contact our Experts at 954-736-4314. We’ll identify the problem right away and can replace your thermostat, if necessary. 

Some of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of routine furnace maintenance. It’s crucial to have this service completed once a year, because it may help reduce breakdowns, boost your furnace’s energy efficiency and may even make it last longer.
