Restoring a Furnace That Wont Stay Lit

A broken furnace is tedious to put up with. There are several reasons this may happen, but one of the most frequent is a problem with the burners or associated components.

Newer models don’t depend on pilot lights to keep the furnace ignited. Instead, they utilize electronic ignition. If this ignition fails, the burners can’t function like they do normally.

When your gas furnace is functioning correctly, here’s how it should operate:

  • The thermostat tells your furnace to turn on.
  • Your furnace’s draft inducer fan starts to pull fresh air through your furnace.
  • The gas valve opens to send gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor informs your furnace that the pilot has been lit.
  • The gas valve sends gas to the primary burners, which are lit by the pilot light.
  • Your furnace then distributes warm air throughout your house via ductwork.

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

Some of these issues can be resolved on their own, but others require professional servicing. When you need the finest furnace repair in Waldorf, reach out to our furnace Experts at 301-747-3140.

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

1. Malfunctioning 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 damaged, it could work intermittently or not at all. Even if the sensor is operating normally, misaligned positioning leaves it unable to recognize the flame entirely. While you can attempt troubleshooting and cleaning this sensor on your own, contacting a pro like A-PLUS Service Experts will ensure the problem is taken care of quickly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety procedures that shut it off if it gets especially hot. One of the most typical causes is a filthy filter. We suggest inspecting your air filter each month. If you can’t see light through it, swap it out.

3. Thermostat Isn’t Working Right

Your thermostat directs your furnace when it is time to heat your home. When it’s not operating as it’s supposed to, your furnace will struggle to keep your residence warm. This can be a battery or electrical problem, depending on what model of thermostat you have. We recommend referring to your owner’s manual or manufacturer’s website for relevant troubleshooting info. If you still can’t get yours working, get in touch with our Experts at 301-747-3140. We’ll pinpoint the cause promptly and can replace your thermostat, if needed.

Some of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of routine furnace maintenance. It’s highly beneficial to have this service performed once a year, because it can help reduce breakdowns, boost your furnace’s energy efficiency and might even make it last longer.
