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

A damaged furnace is tedious to handle. There are multiple reasons this might happen, but one of the most common is a problem with the burners or relevant components. 

Newer models don’t depend on pilot lights to keep the furnace lit. Instead, they work via electronic ignition. If this ignition stops working correctly, the burners can’t function like they are supposed to. 

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

• The thermostat informs your furnace to activate. 
• Your furnace’s draft inducer fan begins to spin in order to pull fresh air through your furnace. 
• The gas valve opens to move gas into the pilot burner. 
• An electronic spark starts the pilot light. 

• The flame sensor tells your furnace that the pilot has been lit. 
• The gas valve transports gas to the principal burners, which are lit by the pilot light. 
• Your furnace then distributes warm air into your house via ductwork. 

If something malfunctions during this process, your furnace will deactivate for safety concerns. Or it might turn off a few minutes into heating because it’s overheating. 

Several of these malfunctions can be handled on their own, but others are best handled by professional help.

Here are some of the top reasons why your heating isn’t staying lit and what to do moving forward. 

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 malfunctioning, it may work intermittently or not at all. Even if the sensor is operating like it should, incorrect positioning leaves it unable to recognize the flame to begin with. While you may try troubleshooting and cleaning this sensor right away, calling an expert like Service Experts Heating & Air Conditioning will guarantee the problem is handled swiftly and correctly. 

2. Overheated Furnace 

Your furnace contains built-in safety procedures that deactivates your furnace if it gets especially hot. One of the most common causes is a dirty filter. We suggest reviewing your air filter monthly. 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 house. When it’s not functioning as it’s supposed to, your furnace will require more energy to keep your residence warm. This can be a battery or electrical problem, depending on what type of thermostat you own. We recommend reviewing your owner’s manual or manufacturer’s website for needed troubleshooting details. If you still can’t get yours working, contact our Experts at 954-736-4314. We’ll find the cause right away and can replace your thermostat, if needed. 

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 highly beneficial to have this service performed once a year, because it can help reduce breakdowns, boost your furnace’s energy efficiency and can even make it survive longer.
