3 Explanations Why Your Furnace Isnt Staying Lit and How to Solve It

A damaged furnace is exhausting to put up with. There are multiple reasons this might happen, but one of the most common is a problem with the burners or related parts.

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

When your gas furnace is functioning properly, here’s how it should work:

  • The thermostat tells your furnace to activate.
  • Your furnace’s draft inducer fan starts to draw 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 informs your furnace that the pilot is burning.
  • The gas valve transports gas to the central burners, which are lit by the pilot light.
  • Your furnace then transports warm air throughout your home via ductwork.

If something fails during this procedure, your furnace will stop for safety reasons. Or it might deactivate a few minutes into heating because it’s overheating.

Some of these issues can be fixed on their own, but others need professional help. When you want the top furnace repair in Voorhees, get in touch with our furnace Experts at 856-310-4824. We service all brands and our work is supported by a 100% Satisfaction Guarantee for a year.*

Here are some of the most common reasons why your furnace isn’t staying lit and what to do about it.

1. Malfunctioning 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 could work intermittently or not at all. Even if the sensor is running as normal, misaligned positioning leaves it unable to identify the flame at all. While you can try troubleshooting and cleaning this sensor right away, calling a pro like Atmostemp Service Experts will guarantee the problem is handled quickly and correctly.

2. Furnace is Too Warm

Your furnace uses built-in safety procedures that force a shutdown if it gets especially hot. One of the most typical causes is a filthy filter. We recommend checking your air filter monthly. If you can’t see light through it, swap it out.

3. Thermostat is Malfunctioning

Your thermostat directs your furnace when it is time to heat your residence. When it’s not working normally, your furnace will have trouble keeping your home warm. This can be a battery or electrical issue, depending on what kind of thermostat you own. We suggest opening your owner’s manual or manufacturer’s website for needed troubleshooting info. If you still can’t get yours working, contact our Experts at 856-310-4824. We’ll uncover the cause right away and can replace your thermostat, if that is required.

Some of these issues, like a dirty flame sensor or an overheated furnace, are a result of a lack of consistent furnace maintenance. It’s vital to have this service completed yearly, because it can help prevent breakdowns, enhance your furnace’s energy efficiency and could even make it live longer.
