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

A damaged furnace is exhausting to put up with. There are many reasons this may happen, but one of the most likely is an issue with the burners or relevant systems. 

Newer systems don’t rely on pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition is damaged, the burners can’t work like they do normally. 

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

• The thermostat directs your furnace to activate. 
• Your furnace’s draft inducer fan begins to spin in order to draw fresh air toward your furnace. 
• The gas valve opens to send gas into the pilot burner. 
• An electronic spark lights the pilot light. 

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

If something fails during this procedure, your furnace will shut down for safety reasons. Or it might stop a few minutes into heating because it’s getting too hot. 

Some of these problems can be resolved on their own, but others are best handled by professional help. When you need the top furnace repair in Dallas, contact our heat Experts at 469-250-0932. We service all brands and our services are backed by a 100% Satisfaction Guarantee for a year.* 

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

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 damaged, it could work inconsistently or not at all. Even if the sensor is functioning like it should, incorrect positioning leaves it unable to recognize the flame at all. While you can start troubleshooting and cleaning this sensor by yourself, hiring a professional like Levy & Son Service Experts will guarantee the problem is resolved swiftly and correctly. 

2. Furnace is Too Hot 

Your furnace uses built-in safety functions that force a shutdown if it gets too hot. One of the most frequent causes is a clogged filter. We encourage evaluating your air filter each month. If you can’t see light through it, change it. 

3. Thermostat is Malfunctioning 

Your thermostat directs your furnace when it needs to heat your house. When it’s not functioning correctly, your furnace will struggle to keep your house warm. This can be a battery or electrical malfunction, depending on what model of thermostat you own. We encourage checking your owner’s manual or manufacturer’s website for relevant troubleshooting info. If you still can’t get yours working, contact our Experts at 469-250-0932. We’ll uncover the cause swiftly and can replace your thermostat, if necessary. 

Several of these issues, including a dirty flame sensor or an overheated furnace, are caused by a lack of consistent furnace maintenance. It’s crucial to have this service completed yearly, because it might help minimize breakdowns, enhance your furnace’s energy efficiency and might even make it survive longer.
