How to Fix a Furnace That Wont Stay Lit

A faulty furnace is frustrating to put up with. There are lots of reasons this may happen, but one of the most common is a problem with the burners or relevant components.

Newer systems don’t rely on pilot lights to keep the furnace lit. Instead, they use electronic ignition. If this ignition malfunctions, the burners can’t perform like they are supposed to.

When your gas furnace is running correctly, here’s how it should run:

  • The thermostat directs your furnace to turn on.
  • Your furnace’s draft inducer fan starts 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 is burning.
  • The gas valve sends gas to the primary burners, which are lit by the pilot light.
  • Your furnace then provides warm air across your residence via ductwork.

If something malfunctions during this process, your furnace will deactivate for safety purposes. Or it might stop a few minutes into heating because it’s getting too hot.

Several of these problems can be repaired on their own, but others require professional assistance. When you want the finest furnace repair in Dallas, contact our furnace Experts at 469-250-0932. We work with all brands and our work is backed by a 100% Satisfaction Guarantee for a year.*

Here are a number of the typical reasons why your heating isn’t staying lit and what to do to fix it.

1. Faulty 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 damaged, it could work erratically or not at all. Even if the sensor is running like it should, incorrect positioning leaves it unable to detect the flame entirely. While you may try troubleshooting and cleaning this sensor on your own, hiring a pro like Levy & Son Service Experts will make sure the problem is resolved quickly and correctly.

2. Furnace is Too Warm

Your furnace contains built-in safety functions that shut it off if it gets especially hot. One of the most common causes is a dirty filter. We recommend reviewing your air filter monthly. If you can’t see light through it, replace it.

3. Thermostat Isn’t Working Right

Your thermostat directs your furnace when it is time to heat your residence. When it’s not functioning correctly, your furnace will require more energy to keep your residence warm. This can be a battery or electrical issue, depending on what type of thermostat you own. We encourage checking your owner’s manual or manufacturer’s website for needed troubleshooting details. If you still can’t get yours working, reach out to our Experts at 469-250-0932. We’ll discover the issue swiftly and can replace your thermostat, if necessary.

Several of these issues, such as a dirty flame sensor or an overheated furnace, are caused by a lack of proper furnace maintenance. It’s crucial to have this service done once a year, because it might help stop breakdowns, increase your furnace’s energy efficiency and can even make it last longer.
