How to Repair a Furnace That Wont Stay Lit

A malfunctioning furnace is frustrating to handle. There are lots of reasons this might happen, but one of the most frequent is an issue with the burners or related systems.

Newer models don’t depend on pilot lights to keep the furnace going. Instead, they utilize electronic ignition. If this ignition stops working correctly, the burners will not perform like they are supposed to.

When your gas furnace is running 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 through your furnace.
  • The gas valve opens to send gas into the pilot burner.
  • An electronic spark lights the pilot light.
  • The flame sensor directs your furnace that the pilot has been lit.
  • The gas valve moves gas to the principal burners, which are lit by the pilot light.
  • Your furnace then transports warm air throughout your home via ductwork.

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

A number of of these issues can be handled on their own, but others require professional assistance.

Here are a few of the top reasons why your heater isn’t staying lit and what to do to fix it.

1. Dirty 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 faulty, it could work inconsistently or not at all. Even if the sensor is running normally, misaligned positioning leaves it unable to identify the flame entirely. While you can attempt troubleshooting and cleaning this sensor right away, contacting a professional like Rob's Albertan Service Experts will guarantee the problem is fixed swiftly and correctly.

2. Furnace is Too Warm

Your furnace utilizes built-in safety procedures that deactivates your furnace if it gets dangerously hot. One of the most common causes is a clogged filter. We encourage checking your air filter every month. If you can’t see light through it, replace it.

3. Thermostat Malfunction

Your thermostat tells your furnace when it needs to heat your residence. When it’s not working correctly, your furnace will struggle to keep your house warm. This can be a battery or electrical problem, depending on what type of thermostat you own. We suggest referring to your owner’s manual or manufacturer’s website for needed troubleshooting instructions. If you still can’t get yours working, contact our Experts at 780-800-9047. We’ll identify the issue swiftly and can replace your thermostat, if necessary.

Some of these issues, such as a dirty flame sensor or an overheated furnace, are caused by a lack of routine furnace maintenance. It’s vital to have this service done annually, because it may help minimize breakdowns, enhance your furnace’s energy efficiency and may even make it live longer.
