Repairing a Furnace That Wont Stay Lit

A malfunctioning furnace is tedious to put up with. There are many reasons this may happen, but one of the most likely is an issue with the burners or associated systems.

Newer furnaces don’t require pilot lights to keep the furnace lit. Instead, they utilize electronic ignition. If this ignition is damaged, 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 run.
  • Your furnace’s draft inducer fan turns on to bring fresh air into your furnace.
  • The gas valve opens to move gas into the pilot burner.
  • An electronic spark starts the pilot light.
  • The flame sensor tells your furnace that the pilot has been ignited.
  • The gas valve transports gas to the main burners, which are lit by the pilot light.
  • Your furnace then moves warm air throughout your home via ductwork.

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

Several of these issues can be fixed on their own, but others require professional help. When you need the finest furnace repair in Charleston, call our heat Experts at 843-410-6103. We work with all brands and our service is supported by a 100% Satisfaction Guarantee for a year.*

Here are a few 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 system that tells 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 like it should, poor positioning leaves it unable to recognize the flame entirely. While you may try troubleshooting and cleaning this sensor right away, hiring an expert like Pardee Service Experts will ensure the problem is handled promptly and correctly.

2. Furnace is Too Hot

Your furnace uses built-in safety procedures that deactivates your furnace if it gets dangerously hot. One of the most frequent causes is a filthy filter. We suggest reviewing your air filter monthly. If you can’t see light through it, swap it out.

3. Thermostat Isn’t Working Right

Your thermostat tells your furnace when it should heat your house. When it’s not running normally, your furnace will have trouble keeping your home warm. This can be a battery or electrical malfunction, depending on what type of thermostat you use. We suggest checking your owner’s manual or manufacturer’s website for needed troubleshooting info. If you still can’t get yours working, contact our Experts at 843-410-6103. We’ll pinpoint the cause promptly and can replace your thermostat, if needed.

A number of these issues, such as a dirty flame sensor or an overheated furnace, are caused by a lack of proper furnace maintenance. It’s extremely helpful to have this service performed once a year, because it could help prevent breakdowns, improve your furnace’s energy efficiency and may even make it survive longer.
