Fixing a Furnace That Wont Stay Lit

A faulty furnace is a hassle to handle. There are multiple reasons this might happen, but one of the most likely is a problem with the burners or related components.

Newer models don’t use pilot lights to keep the furnace lit. 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 running normally, here’s how it should run:

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

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

Some of these issues can be resolved on their own, but others need professional help. When you want the top furnace repair in Fort Wayne, contact our heat Experts at 260-557-1275. We have experience with all brands and our work is backed by a 100% Satisfaction Guarantee for a year.*

Here are several of the typical reasons why your furnace isn’t staying lit and what to do moving forward.

1. Faulty Flame Sensor

Your furnace’s flame sensor is a safety system that tells your furnace when gas is ignited. If the sensor is dirty or damaged, it may work inconsistently or not at all. Even if the sensor is working like it should, incorrect positioning leaves it unable to identify the flame to begin with. While you may attempt troubleshooting and cleaning this sensor by yourself, hiring an expert like Rolf Griffin Service Experts will make sure the problem is fixed promptly and correctly.

2. Furnace is Too Hot

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

3. Thermostat Malfunction

Your thermostat tells your furnace when it should heat your home. When it’s not functioning like it should, your furnace will require more energy to keep your house warm. This can be a battery or electrical issue, depending on what kind of thermostat you own. We recommend referring to your owner’s manual or manufacturer’s website for specific troubleshooting procedures. If you still can’t get yours working, call our Experts at 260-557-1275. We’ll find the cause swiftly and can replace your thermostat, if necessary.

Several of these issues, including 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 completed every year, because it may help reduce breakdowns, increase your furnace’s energy efficiency and could even make it survive longer.
