3 Explanations Why Your Furnace Isnt Staying Lit and How to Solve It

A damaged furnace is a hassle to handle. There are several reasons this may happen, but one of the most likely is an issue with the burners or relevant components.

Newer systems don’t count on pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition stops working correctly, the burners will not function like they should.

When your gas furnace is functioning properly, here’s how it should operate:

  • The thermostat directs your furnace to run.
  • Your furnace’s draft inducer fan begins to spin in order to draw fresh air toward your furnace.
  • The gas valve opens to move gas into the pilot burner.
  • An electronic spark lights the pilot light.
  • The flame sensor informs your furnace that the pilot is burning.
  • The gas valve directs gas to the principal burners, which are lit by the pilot light.
  • Your furnace then distributes warm air across your house via ductwork.

If something malfunctions during this sequence, your furnace will deactivate for safety reasons. Or it might deactivate a few minutes into heating because it’s too warm.

Several of these issues can be resolved on their own, but others are best handled by professional servicing.

Here are a number of the top reasons why your heater 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 informs your furnace when gas is ignited. If the sensor is dirty or damaged, it could work inconsistently or not at all. Even if the sensor is functioning as normal, poor positioning leaves it unable to sense the flame to begin with. While you may start troubleshooting and cleaning this sensor by yourself, calling a professional like Orangutan Home Services will guarantee the problem is fixed promptly and correctly.

2. Overheated Furnace

Your furnace utilizes built-in safety procedures that shut it off if it gets dangerously hot. One of the most common causes is a dirty filter. We suggest checking your air filter each month. If you can’t see light through it, change it.

3. Thermostat Isn’t Working Right

Your thermostat directs your furnace when it needs to heat your home. When it’s not running normally, your furnace will struggle to keep your residence warm. This can be a battery or electrical issue, depending on what type of thermostat you use. We suggest reviewing your owner’s manual or manufacturer’s website for useful troubleshooting info. If you still can’t get yours working, call our Experts at 602-906-0111. We’ll pinpoint the issue quickly and can replace your thermostat, if that is required.

A number of these issues, including a dirty flame sensor or an overheated furnace, are a result of a lack of proper furnace maintenance. It’s vital to have this service done yearly, because it might help minimize breakdowns, enhance your furnace’s energy efficiency and could even make it live longer.
