Fixing a Furnace That Wont Stay Lit

A malfunctioning furnace is exhausting to handle. There are several reasons this may happen, but one of the most common is an issue with the burners or related systems.

Newer furnaces don’t require pilot lights to keep the furnace going. Instead, they use electronic ignition. If this ignition malfunctions, the burners can’t perform like they do normally.

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

  • The thermostat directs your furnace to turn on.
  • Your furnace’s draft inducer fan begins to spin in order to bring fresh air toward your furnace.
  • The gas valve opens to direct 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 moves gas to the primary burners, which are lit by the pilot light.
  • Your furnace then sends warm air into your residence via ductwork.

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

Some of these problems can be repaired on their own, but others need professional assistance. When you need the best furnace repair in Orlando, contact our furnace Experts at 407-329-7661. We have experience with all brands and our work is backed by a 100% Satisfaction Guarantee for a year.*

Here are a few of the typical reasons why your heater isn’t staying lit and what to do to fix it.

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 erratically or not at all. Even if the sensor is running as normal, incorrect positioning leaves it unable to detect the flame entirely. While you could start troubleshooting and cleaning this sensor on your own, calling a professional like Service Experts Heating & Air Conditioning will guarantee the problem is resolved swiftly and correctly.

2. Overheated Furnace

Your furnace utilizes built-in safety functions that force a shutdown if it gets especially hot. One of the most common causes is a dirty filter. We encourage inspecting your air filter each month. If you can’t see light through it, swap it out.

3. Thermostat Malfunction

Your thermostat commands your furnace when it should heat your home. When it’s not running like it should, your furnace will require more energy to keep your residence warm. This can be a battery or electrical issue, depending on what type of thermostat you have. We encourage opening your owner’s manual or manufacturer’s website for useful troubleshooting information. If you still can’t get yours working, call our Experts at 407-329-7661. We’ll identify the problem quickly and can replace your thermostat, if necessary.

Several of these issues, including a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s important to have this service completed annually, because it can help reduce breakdowns, improve your furnace’s energy efficiency and may even make it last longer.
