3 Reasons Why Your Furnace Isn’t Staying Lit and How to Repair It
A malfunctioning furnace is frustrating to handle. There are several reasons this can happen, but one of the most frequent is an issue with the burners or relevant components.
Newer models don’t rely on pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition stops working correctly, the burners won’t work like they are supposed to.
When your gas furnace is running correctly, here’s how it should operate:
- The thermostat directs your furnace to activate.
- Your furnace’s draft inducer fan starts to pull fresh air through your furnace.
- The gas valve opens to move gas into the pilot burner.
- An electronic spark starts the pilot light.
- The flame sensor informs your furnace that the pilot has been ignited.
- The gas valve directs gas to the main 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 shut down for safety purposes. Or it might deactivate a few minutes into heating because it’s overheating.
A number of of these issues can be resolved on their own, but others need professional help. When you want the top furnace repair in the U.S., call our furnace Experts at 866-397-3787. We have experience with all brands and our work is ensured by a 100% Satisfaction Guarantee for a year.*
Here are a number of the main reasons why your heating isn’t staying lit and what to do to fix it.
1. Dirty Flame Sensor
Your furnace’s flame sensor is a safety system that notifies your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it might work erratically or not at all. Even if the sensor is running normally, incorrect positioning leaves it unable to identify the flame at all. While you may start troubleshooting and cleaning this sensor on your own, calling a pro like Service Experts Heating, Air Conditioning & Plumbing will ensure the problem is handled swiftly and correctly.
2. Furnace is Too Hot
Your furnace utilizes built-in safety features that shut it off if it gets especially hot. One of the most frequent causes is a dirty filter. We encourage evaluating your air filter every month. If you can’t see light through it, change it.
3. Thermostat Malfunction
Your thermostat commands your furnace when it should heat your home. When it’s not operating correctly, your furnace will struggle to keep your home warm. This can be a battery or electrical malfunction, depending on what kind of thermostat you own. We recommend checking your owner’s manual or manufacturer’s website for required troubleshooting details. If you still can’t get yours working, contact our Experts at 866-397-3787. We’ll find the cause right away and can replace your thermostat, if needed.
Several of these issues, such as a dirty flame sensor or an overheated furnace, are caused by a lack of consistent furnace maintenance. It’s crucial to have this service done yearly, because it could help reduce breakdowns, enhance your furnace’s energy efficiency and can even make it last longer.
