Repairing 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 a problem with the burners or relevant systems.

Newer furnaces don’t require pilot lights to keep the furnace ignited. Instead, they use electronic ignition. If this ignition stops working correctly, the burners will not function like they should.

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

  • The thermostat informs your furnace to run.
  • Your furnace’s draft inducer fan starts to pull fresh air into your furnace.
  • The gas valve opens to move gas into the pilot burner.
  • An electronic spark ignites the pilot light.
  • The flame sensor directs your furnace that the pilot is burning.
  • The gas valve transports gas to the main burners, which are lit by the pilot light.
  • Your furnace then pushes warm air across your home via ductwork.

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

A number of of these malfunctions can be repaired on their own, but others are best handled by professional assistance.

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

1. Faulty Flame Sensor

Your furnace’s flame sensor is a safety system that notifies your furnace when gas is ignited. If the sensor is dirty or malfunctioning, it could work erratically or not at all. Even if the sensor is functioning like it should, poor positioning leaves it unable to recognize the flame entirely. While you can start troubleshooting and cleaning this sensor on your own, contacting an expert like Golden Seal Service Experts will guarantee the problem is handled swiftly and correctly.

2. Furnace is Too Hot

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

3. Thermostat is Malfunctioning

Your thermostat directs your furnace when it is time to heat your house. When it’s not working like it should, your furnace will have trouble keeping your home warm. This can be a battery or electrical issue, depending on what kind of thermostat you own. We recommend opening your owner’s manual or manufacturer’s website for needed troubleshooting instructions. If you still can’t get yours working, call our Experts at 630-246-2698. We’ll uncover the issue swiftly and can replace your thermostat, if that is required.

A number of these issues, like a dirty flame sensor or an overheated furnace, are a result of a lack of consistent furnace maintenance. It’s important to have this service done yearly, because it could help stop breakdowns, improve your furnace’s energy efficiency and can even make it last longer.
