A gas fireplace with a failed valve or sensor will challenge you to keep it lit for 20 minutes or an hour. On most occasions, this implies that either your thermopile or oxypilot needs cleanliness.  The oxypilot plays a vital role in monitoring the oxygen of your fireplace.

On the other hand, the thermopile monitors the temperature of your fireplace. So, check the two components; if they aren’t dirty, you must replace them. Rarely, a fireplace that keeps going out can be due to a gas leak. But, this situation is highly unusual that comes with multiple problems.

Lighting up a gas fireplace starts by adjusting the pilot light towards the on position. Sometimes you may be forced to hold it for a few seconds to allow the fire to pick up. Be careful while starting up the fire to observe the progress.

Once the fire is lit, you will see two flames, i.e., one above the burner while the other over the thermopile. If the fireplace has a dirty pilot, cleaning can be a better solution; else, the flame will be feeble. This will lead to dropped temperature, shut off gas, and lifted away flame from the thermocouple.

Additionally, about the nature of the flame, the outer flame should be dark blue and sky blue in the center. A yellow pilot light can imply excess air, dust, oil, dirt, and grime in the system.

This sensor is designed to put out a gas fire under an insufficient oxygen supply in the room. Yeah, it’s a safety technology that spares you from carbon poisoning.

The first thing to do will be to check the status of the thermocouple before diagnosing other issues. Inspect for a stick that resembles a thermometer; that’s the thermocouple.

You want to ensure the component is in the pilot direction. After spotting the part, the next thing will be to grab sandpaper to scarp down the dust, grime, or whatever from the tip of your thermocouple. Remember, doing so will remove any oxidation or soot, retaining the workability of the device.

Step 3: Testing your fireplace

In most cases, the thermopile touch-up can be an excellent solution to retain your fireplace in good working condition. Here, you need to turn on the gas and light it. If it keeps on going off, it is now time to switch the gas and move to the next step.

Step 7: Sensor and oxypilot replacement

If the fireplace keeps showing the initial problem, maybe it’s time to go for a replacement. Replacing the oxypilot or sensor can be an excellent solution to your fireplace that keeps going out. Under this stage, I recommend seeking the help of an expert because it involves part replacements.

But, if you have the necessary skills and knowledge of replacement, go on and do it yourself. It would help if you were careful about replacing the existing parts with the right ones and doing the job correctly. Any mess can ruin the need for a replacement.
