Restoring a Furnace That Wont Stay Lit

A broken furnace is exhausting to put up with. There are multiple reasons this can happen, but one of the most common is something wrong with the burners or related components.

Newer furnaces don’t count on pilot lights to keep the furnace ignited. Instead, they work via electronic ignition. If this ignition stops working correctly, the burners won’t perform like they do normally.

When your gas furnace is performing normally, here’s how it should operate:

  • The thermostat directs your furnace to turn on.
  • Your furnace’s draft inducer fan begins to spin in order to pull fresh air into your furnace.
  • The gas valve opens to send gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor informs your furnace that the pilot has been ignited.
  • The gas valve moves gas to the central burners, which are lit by the pilot light.
  • Your furnace then provides warm air into your residence via ductwork.

If something goes wrong during this process, your furnace will deactivate for safety reasons. Or it might shut down a few minutes into heating because it’s too warm.

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

Here are several of the main reasons why your heating 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 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 working as normal, poor positioning leaves it unable to identify the flame to begin with. While you may try troubleshooting and cleaning this sensor on your own, trusting an expert like Peitz Service Experts will guarantee the problem is fixed quickly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety features that deactivates your furnace if it gets dangerously hot. One of the most frequent causes is a clogged filter. We suggest evaluating your air filter monthly. If you can’t see light through it, swap it out.

3. Thermostat Malfunction

Your thermostat commands your furnace when it is time to heat your residence. When it’s not running correctly, your furnace will require more energy to keep your residence warm. This can be a battery or electrical issue, depending on what kind of thermostat you use. We recommend opening your owner’s manual or manufacturer’s website for necessary troubleshooting details. If you still can’t get yours working, reach out to our Experts at 605-223-0307. We’ll uncover the issue promptly and can replace your thermostat, if that is required.

Some of these issues, including a dirty flame sensor or an overheated furnace, are caused by a lack of proper furnace maintenance. It’s extremely helpful to have this service completed once a year, because it might help prevent breakdowns, boost your furnace’s energy efficiency and can even make it last longer.
