Restoring a Furnace That Wont Stay Lit

A damaged furnace is exhausting to deal with. There are lots of reasons this may happen, but one of the most likely is something wrong with the burners or relevant systems.

Newer systems don’t use pilot lights to keep the furnace ignited. Instead, they utilize electronic ignition. If this ignition stops working correctly, the burners can’t work like they do normally.

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

  • The thermostat tells your furnace to turn on.
  • Your furnace’s draft inducer fan starts to draw fresh air toward your furnace.
  • The gas valve opens to direct gas into the pilot burner.
  • An electronic spark lights the pilot light.
  • The flame sensor directs 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 provides warm air throughout your house via ductwork.

If something malfunctions during this sequence, your furnace will turn off for safety reasons. Or it might stop a few minutes into heating because it’s getting too hot.

A number of of these problems can be fixed on their own, but others need professional assistance. When you need the fastest furnace repair in Buffalo, contact our furnace Experts at 716-427-6807.

Here are a number of the most common 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 component that tells your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it might work inconsistently or not at all. Even if the sensor is operating normally, poor positioning leaves it unable to identify the flame entirely. While you may start troubleshooting and cleaning this sensor right away, trusting a professional like Sunbeam Service Experts will guarantee the problem is handled quickly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety functions that deactivates your furnace if it gets too hot. One of the most common causes is a filthy filter. We suggest evaluating your air filter each month. If you can’t see light through it, swap it out.

3. Thermostat is Malfunctioning

Your thermostat informs your furnace when it should heat your residence. When it’s not functioning normally, your furnace will require more energy to keep your home warm. This can be a battery or electrical problem, depending on what kind of thermostat you own. We recommend checking your owner’s manual or manufacturer’s website for required troubleshooting information. If you still can’t get yours working, contact our Experts at 716-427-6807. We’ll identify the issue right away and can replace your thermostat, if that is required.

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 vital to have this service completed every year, because it could help minimize breakdowns, enhance your furnace’s energy efficiency and could even make it last longer.
