Repairing a Furnace That Wont Stay Lit

A broken furnace is tedious to handle. There are many reasons this can happen, but one of the most likely is a problem with the burners or associated systems.

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

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

  • The thermostat informs your furnace to activate.
  • Your furnace’s draft inducer fan starts to bring fresh air into your furnace.
  • The gas valve opens to send 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 primary burners, which are lit by the pilot light.
  • Your furnace then moves warm air throughout your residence via ductwork.

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

A number of of these malfunctions can be fixed on their own, but others require professional help.

Here are several of the most common 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 notifies your furnace when gas is ignited. If the sensor is dirty or faulty, it may work intermittently or not at all. Even if the sensor is operating normally, incorrect positioning leaves it unable to sense the flame at all. While you may attempt troubleshooting and cleaning this sensor right away, hiring an expert like Becht/Givens Service Experts will make sure the problem is fixed swiftly and correctly.

2. Overheated Furnace

Your furnace contains built-in safety procedures that shut it off if it gets too hot. One of the most frequent causes is a filthy filter. We encourage checking your air filter every month. If you can’t see light through it, replace it.

3. Thermostat is Malfunctioning

Your thermostat tells your furnace when it is time to heat your home. When it’s not working normally, your furnace will struggle to keep your residence warm. This can be a battery or electrical malfunction, depending on what type of thermostat you have. We recommend opening your owner’s manual or manufacturer’s website for necessary troubleshooting info. If you still can’t get yours working, call our Experts at 502-785-8230. We’ll discover the cause promptly and can replace your thermostat, if necessary.

A number of these issues, including a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s highly beneficial to have this service done every year, because it may help prevent breakdowns, increase your furnace’s energy efficiency and may even make it survive longer.
