Repairing a Furnace That Wont Stay Lit

A broken furnace is a hassle to put up with. There are multiple reasons this may happen, but one of the most frequent is a problem with the burners or relevant systems.

Newer models don’t count on pilot lights to keep the furnace going. Instead, they use electronic ignition. If this ignition malfunctions, the burners will not function like they should.

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

  • The thermostat tells your furnace to activate.
  • Your furnace’s draft inducer fan starts to draw fresh air toward your furnace.
  • The gas valve opens to send gas into the pilot burner.
  • An electronic spark lights the pilot light.
  • The flame sensor tells your furnace that the pilot has been ignited.
  • The gas valve sends gas to the primary burners, which are lit by the pilot light.
  • Your furnace then pushes warm air across your home via ductwork.

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

Several of these problems can be handled on their own, but others need professional help. When you are looking for the best furnace repair in Fort Worth, contact our heating Experts at 817-380-5647. We repair all brands and our service is ensured by a 100% Satisfaction Guarantee for a year.*

Here are several of the most common reasons why your furnace isn’t staying lit and what to do to fix it.

1. Dirty Flame Sensor

Your furnace’s flame sensor is a safety feature that tells your furnace when gas is ignited. If the sensor is dirty or faulty, it might work intermittently or not at all. Even if the sensor is running as normal, misaligned positioning leaves it unable to recognize the flame at all. While you can attempt troubleshooting and cleaning this sensor on your own, calling a professional like Calverley Service Experts will guarantee the problem is resolved swiftly and correctly.

2. Furnace is Too Warm

Your furnace has built-in safety procedures that deactivates your furnace if it gets especially hot. One of the most frequent causes is a clogged filter. We encourage inspecting your air filter every month. If you can’t see light through it, swap it out.

3. Thermostat is Malfunctioning

Your thermostat commands your furnace when it needs to heat your residence. When it’s not running properly, your furnace will have trouble keeping your residence warm. This can be a battery or electrical issue, depending on what type of thermostat you use. We suggest opening your owner’s manual or manufacturer’s website for useful troubleshooting details. If you still can’t get yours working, contact our Experts at 817-380-5647. We’ll discover the issue swiftly and can replace your thermostat, if needed.

Some of these issues, such as a dirty flame sensor or an overheated furnace, are due to a lack of consistent furnace maintenance. It’s highly beneficial to have this service done annually, because it might help minimize breakdowns, increase your furnace’s energy efficiency and could even make it survive longer.
