Repairing a Furnace That Wont Stay Lit

A malfunctioning furnace is a hassle to deal with. There are lots of reasons this might happen, but one of the most common is something wrong with the burners or relevant parts.

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

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

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

If something breaks down during this process, your furnace will stop for safety concerns. Or it might shut down a few minutes into heating because it’s overheating.

Some of these malfunctions can be resolved on their own, but others are best handled by professional assistance.

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

1. Faulty Flame Sensor

Your furnace’s flame sensor is a safety component that notifies your furnace when gas is ignited. If the sensor is dirty or faulty, it may work erratically or not at all. Even if the sensor is working as normal, misaligned positioning leaves it unable to recognize the flame entirely. While you can start troubleshooting and cleaning this sensor on your own, trusting a professional like TML Service Experts will make sure the problem is taken care of swiftly and correctly.

2. Furnace is Too Hot

Your furnace has built-in safety features that shut it off if it gets especially hot. One of the most frequent causes is a filthy filter. We encourage inspecting your air filter each month. If you can’t see light through it, change it.

3. Thermostat Isn’t Working Right

Your thermostat tells your furnace when it is time to heat your house. When it’s not working as it’s supposed to, your furnace will require more energy to keep your residence warm. This can be a battery or electrical problem, depending on what kind of thermostat you use. We recommend reviewing your owner’s manual or manufacturer’s website for needed troubleshooting procedures. If you still can’t get yours working, reach out to our Experts at 208-488-4892. We’ll uncover the cause right away and can replace your thermostat, if that is required.

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