Despite being advertised as “low-maintenance” appliances, gas log fireplaces require regular inspections and cleanings to keep them working properly. When these fire features break down, they can be difficult to fix, but there are a few handyman techniques for quick repairs that you can use to get your fireplace back up and running.
The first thing to check is the obvious: Is the gas turned on? If the flames won’t light, there could be a problem with the burner orifice (an opening in the tubes that supply the fuel that mixes with air to produce a flame). This can be caused by dirt and sediment from burning materials, so it is important to have your fireplace serviced regularly.
Another issue that is sometimes encountered with gas fireplaces is a lack of heat. This can be due to a number of things, including the burner not getting enough fuel to ignite, a lack of oxygen from clogged logs or a defective thermocouple. The latter is especially dangerous, because it means there is a leak or blockage in the combustion chamber and that carbon monoxide could be entering your home.
If you are able to get the flames to turn on, but they aren’t producing much heat, it might be time for a replacement or upgrade of the burner and/or logs. Also, if your logs are showing signs of fading and discoloration, it might be time to replace them with newer models.
It is always best to consult your owner’s manual for gas log fireplace repair and maintenance tips before you attempt any fixes yourself. This will help you locate the proper tools and parts, so you can perform your repairs properly and efficiently.
Before beginning any work, it is essential to shut off the gas, using the valve located on the front of the fireplace or in the basement or garage. Once the gas is off, remove the fireplace doors. Some may be held in place with screws, while others are secured by spring clips. Once the glass is removed, place it on a clean surface so that it doesn’t get scratched or damaged during the cleaning process. Next, remove the lava rocks and logs. Place them on an old towel to prevent them from getting dirty or scratched during the removal process.
Once you’ve gathered the tools and supplies, it is time to begin your repairs. Start by shutting off the gas again, if necessary. This is usually done by turning the valve to the “Off” position and then reversing it to the “On” position. This will prevent any accidental gas flow while you’re working on your fireplace.
Once the valve is closed, you can now begin working on your fireplace. The first thing you’ll want to do is to ensure that the pilot light is still lit. If it isn’t, you should follow the manufacturer’s instructions for relighting it. This includes making sure the flame is blue and that it is burning steadily. Then, you can also inspect the thermopile to make sure it’s in good condition and positioned correctly over the pilot light.
