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

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

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

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

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

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

If something breaks down during this procedure, your furnace will shut down for safety reasons. Or it might deactivate a few minutes into heating because it’s too warm. 

Some of these problems can be fixed on their own, but others need professional help. When you want the top furnace repair in the U.S., call our heating Experts at 866-397-3787. We have experience with all brands and our services are ensured by a 100% Satisfaction Guarantee for a year.* 

Here are a number of the top reasons why your heating isn’t staying lit and what to do about it. 

1. Faulty Flame Sensor 

Your furnace’s flame sensor is a safety system that informs your furnace when gas is ignited. If the sensor is dirty or damaged, it may work erratically or not at all. Even if the sensor is operating as normal, misaligned positioning leaves it unable to recognize the flame entirely. While you can try troubleshooting and cleaning this sensor right away, contacting a pro like Service Experts Heating, Air Conditioning & Plumbing will guarantee the problem is resolved swiftly and correctly. 

2. Furnace is Too Warm 

Your furnace has built-in safety features that force a shutdown if it gets especially hot. One of the most typical causes is a clogged filter. We suggest evaluating your air filter monthly. If you can’t see light through it, replace it. 

3. Thermostat Isn’t Working Right 

Your thermostat tells your furnace when it needs to heat your residence. When it’s not functioning like it should, your furnace will struggle to keep your house warm. This can be a battery or electrical issue, depending on what kind of thermostat you own. We recommend checking your owner’s manual or manufacturer’s website for relevant troubleshooting instructions. If you still can’t get yours working, contact our Experts at 866-397-3787. We’ll identify the issue swiftly 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 proper furnace maintenance. It’s vital to have this service completed yearly, because it could help prevent breakdowns, enhance your furnace’s energy efficiency and may even make it survive longer.
