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

A broken furnace is exhausting to handle. There are many reasons this might happen, but one of the most frequent is an issue with the burners or associated parts. 

Newer systems don’t count on pilot lights to keep the furnace lit. Instead, they use electronic ignition. If this ignition stops working correctly, the burners won’t function like they do normally. 

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

• The thermostat directs your furnace to turn on. 
• Your furnace’s draft inducer fan starts to pull fresh air toward 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 principal burners, which are lit by the pilot light. 
• Your furnace then transports warm air into your home via ductwork. 

If something breaks down during this process, your furnace will stop for safety concerns. Or it might shut down a few minutes into heating because it’s overheating. 

A number of of these issues can be handled on their own, but others need professional servicing. When you want the best furnace repair in Fort Lauderdale, call our heat Experts at 954-736-4314.

Here are several of the typical reasons why your heater isn’t staying lit and what to do about it. 

1. Malfunctioning 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 faulty, it may work inconsistently or not at all. Even if the sensor is operating like it should, incorrect positioning leaves it unable to identify the flame entirely. While you could attempt troubleshooting and cleaning this sensor by yourself, contacting an expert like Service Experts Heating & Air Conditioning will make sure the problem is handled quickly and correctly. 

2. Furnace is Too Warm 

Your furnace uses built-in safety functions that deactivates your furnace if it gets too hot. One of the most common causes is a clogged filter. We encourage inspecting your air filter monthly. If you can’t see light through it, change it. 

3. Thermostat Isn’t Working Right 

Your thermostat tells your furnace when it needs to heat your house. When it’s not working like it should, your furnace will struggle to keep your home warm. This can be a battery or electrical malfunction, depending on what type of thermostat you have. We encourage referring to your owner’s manual or manufacturer’s website for required troubleshooting instructions. If you still can’t get yours working, reach out to our Experts at 954-736-4314. We’ll find the issue promptly and can replace your thermostat, if necessary. 

A number of these issues, including a dirty flame sensor or an overheated furnace, are due to a lack of consistent furnace maintenance. It’s extremely helpful to have this service done yearly, because it might help reduce breakdowns, increase your furnace’s energy efficiency and can even make it survive longer.
