3 Explanations Why Your Furnace Isn’t Staying Lit and How to Repair It
A damaged furnace is a hassle to deal with. There are multiple reasons this might happen, but one of the most common is something wrong with the burners or related components.
Newer models don’t depend on pilot lights to keep the furnace ignited. Instead, they work via electronic ignition. If this ignition stops working correctly, the burners will not perform like they do normally.
When your gas furnace is performing normally, here’s how it should work:
- The thermostat directs your furnace to activate.
- Your furnace’s draft inducer fan begins to spin in order to bring fresh air through 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 has been ignited.
- The gas valve transports gas to the central burners, which are lit by the pilot light.
- Your furnace then provides warm air across your home via ductwork.
If something malfunctions during this process, your furnace will deactivate for safety purposes. Or it might turn off a few minutes into heating because it’s overheating.
Several of these problems can be resolved on their own, but others need professional help. When you need the top furnace repair in the U.S., get in touch with our heating Experts at 866-397-3787. We service all brands and our work is supported by a 100% Satisfaction Guarantee for a year.*
Here are some of the typical reasons why your heater isn’t staying lit and what to do moving forward.
1. Faulty 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 faulty, it could work erratically or not at all. Even if the sensor is working normally, misaligned positioning leaves it unable to identify the flame entirely. While you could attempt troubleshooting and cleaning this sensor on your own, trusting an expert like Service Experts Heating, Air Conditioning & Plumbing will ensure the problem is handled promptly and correctly.
2. Overheated Furnace
Your furnace uses built-in safety procedures that deactivates your furnace if it gets dangerously hot. One of the most typical causes is a dirty filter. We recommend reviewing your air filter monthly. If you can’t see light through it, change it.
3. Thermostat Malfunction
Your thermostat informs your furnace when it is time to heat your home. When it’s not running like it should, your furnace will require more energy to keep your house warm. This can be a battery or electrical problem, depending on what type of thermostat you use. We suggest checking your owner’s manual or manufacturer’s website for necessary troubleshooting procedures. If you still can’t get yours working, get in touch with our Experts at 866-397-3787. We’ll uncover the problem promptly and can replace your thermostat, if necessary.
Some of these issues, including 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 every year, because it could help minimize breakdowns, improve your furnace’s energy efficiency and could even make it live longer.
