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

A broken furnace is exhausting to deal with. There are multiple reasons this might happen, but one of the most common is an issue with the burners or relevant components. 

Newer systems don’t rely on pilot lights to keep the furnace going. Instead, they utilize electronic ignition. If this ignition malfunctions, the burners can’t work like they are supposed to. 

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

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

• The flame sensor directs your furnace that the pilot has been lit. 
• The gas valve sends gas to the central burners, which are lit by the pilot light. 
• Your furnace then moves warm air across your house via ductwork. 

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

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

Here are several of the typical 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 feature that tells your furnace when gas is ignited. If the sensor is dirty or damaged, it could work erratically or not at all. Even if the sensor is operating normally, poor positioning leaves it unable to sense the flame to begin with. While you can attempt troubleshooting and cleaning this sensor right away, contacting a professional like Service Experts Heating & Air Conditioning will make sure the problem is handled quickly and correctly. 

2. Overheated Furnace 

Your furnace contains built-in safety features that force a shutdown if it gets too hot. One of the most frequent causes is a filthy filter. We encourage inspecting your air filter each month. If you can’t see light through it, replace it. 

3. Thermostat is Malfunctioning 

Your thermostat commands your furnace when it needs to heat your house. When it’s not functioning properly, your furnace will have trouble keeping your residence warm. This can be a battery or electrical issue, depending on what type of thermostat you have. We suggest opening your owner’s manual or manufacturer’s website for relevant troubleshooting details. If you still can’t get yours working, get in touch with our Experts at 954-736-4314. We’ll identify the issue quickly and can replace your thermostat, if needed. 

A number of these issues, such as a dirty flame sensor or an overheated furnace, are due to a lack of routine furnace maintenance. It’s important to have this service done every year, because it might help minimize breakdowns, enhance your furnace’s energy efficiency and could even make it survive longer.
