3 Causes Why Your Furnace Isnt Staying Lit and How to Fix It

A damaged furnace is a hassle to handle. There are several reasons this may happen, but one of the most likely is an issue with the burners or related components.

Newer furnaces don’t use pilot lights to keep the furnace lit. Instead, they work via electronic ignition. If this ignition malfunctions, the burners can’t work like they should.

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

  • The thermostat directs your furnace to turn on.
  • Your furnace’s draft inducer fan begins to spin in order to pull fresh air toward your furnace.
  • The gas valve opens to direct gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor directs your furnace that the pilot is burning.
  • The gas valve moves gas to the primary burners, which are lit by the pilot light.
  • Your furnace then moves warm air into your house via ductwork.

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

Several of these issues can be resolved on their own, but others need professional help. When you need the best furnace repair in Savannah, get in touch with our furnace Experts at 912-208-2399. We repair all brands and our service is supported by a 100% Satisfaction Guarantee for a year.*

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

1. Dirty Flame Sensor

Your furnace’s flame sensor is a safety feature that notifies your furnace when gas is ignited. If the sensor is dirty or faulty, it might work inconsistently or not at all. Even if the sensor is working like it should, poor positioning leaves it unable to recognize the flame entirely. While you could try troubleshooting and cleaning this sensor right away, hiring a pro like Coastal Service Experts will ensure the problem is resolved promptly and correctly.

2. Furnace is Too Warm

Your furnace has built-in safety functions that deactivates your furnace if it gets dangerously hot. One of the most common causes is a filthy filter. We suggest evaluating your air filter monthly. If you can’t see light through it, change it.

3. Thermostat Malfunction

Your thermostat tells your furnace when it should heat your home. When it’s not functioning as it’s supposed to, your furnace will have trouble keeping your residence warm. This can be a battery or electrical problem, depending on what type of thermostat you have. We recommend referring to your owner’s manual or manufacturer’s website for specific troubleshooting procedures. If you still can’t get yours working, call our Experts at 912-208-2399. We’ll identify the problem swiftly and can replace your thermostat, if necessary.

Several of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of routine furnace maintenance. It’s extremely helpful to have this service performed once a year, because it may help stop breakdowns, enhance your furnace’s energy efficiency and could even make it last longer.
