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

A faulty furnace is exhausting to handle. There are many reasons this might happen, but one of the most common is something wrong with the burners or relevant parts.

Newer models don’t require pilot lights to keep the furnace ignited. Instead, they work via electronic ignition. If this ignition fails, the burners won’t work like they are supposed to.

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

• • The thermostat informs your furnace to run.

• • Your furnace’s draft inducer fan starts to bring 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 tells your furnace that the pilot has been lit.

• • The gas valve transports gas to the main burners, which are lit by the pilot light.

• • Your furnace then sends warm air into your home via ductwork.

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

Several of these malfunctions can be fixed on their own, but others need professional servicing. When you need the fastest furnace repair in the U.S., reach out to our heat Experts at . We work with all brands and our service is ensured by a 100% Satisfaction Guarantee for a year.*

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

1. Malfunctioning 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 might work intermittently or not at all. Even if the sensor is working as normal, poor positioning leaves it unable to recognize the flame to begin with. While you could start troubleshooting and cleaning this sensor on your own, contacting an expert like Service Experts Heating, Air Conditioning & Plumbing will guarantee the problem is resolved quickly and correctly.

2. Overheated Furnace

Your furnace contains built-in safety functions that shut it off if it gets too hot. One of the most frequent causes is a dirty filter. We suggest inspecting your air filter each month. If you can’t see light through it, change it.

3. Thermostat Isn’t Working Right

Your thermostat tells your furnace when it should heat your residence. When it’s not working properly, your furnace will struggle to keep your residence warm. This can be a battery or electrical problem, depending on what type of thermostat you own. We suggest checking your owner’s manual or manufacturer’s website for necessary troubleshooting procedures. If you still can’t get yours working, contact our Experts at . We’ll find the problem swiftly and can replace your thermostat, if needed.

A number of these issues, like a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s vital to have this service performed once a year, because it could help stop breakdowns, increase your furnace’s energy efficiency and may even make it last longer.
