Thermocouple issues, pilot light problems, blocked venting systems, safety features, and gas supply issues are common reasons why gas fireplaces shut off. Regular maintenance, cleaning, and professional servicing are essential to prevent unexpected shut-offs.
This is a safety mechanism which prevents the gas from coming out and spilling when filling up the tank. Typically, this indicates that the tank is full. However, you may experience an instance where your tank is not full, yet the gas pump is still clicking off.
The first thing I would look at is the heat sensor on the flame source. It is designed to detect high heat from the flame and shut gas off if that flame goes out. It could become defective and stop sensing the heat from the flame, caused the gas to shut off. Those heat sensors, I believe, can usually be replaced.
Oh, ok. If it keeps clicking even after you turn the unit off, the first and most likely culprit is a clogged ignition system. Food scraps and even grease can sometimes wedge themselves in these systems and cause the stove to continuously click. You will have to get that cleaned out.

Ticking or Popping Sounds
These noises often occur as your fireplace cools down. Metal components contract as they cool, causing those distinct ticks and pops. While usually harmless, excessive noise might indicate warped metal parts that need replacing.
The most common cause of this is dirty or blocked burners, which is the part that you can easily take off to clean.
Fireplace thermocouple replacement costs $150 to $350 total.
A worn-out igniter can periodically fail, and if it keeps trying to light the gas, your furnace will make a clicking sound. The noise may last until the flame ignites or the gas valve closes. This failure and its corresponding clicking noise can also result from the igniter's wiring coming undone.
If your gas stove keeps clicking even after you turn the unit off, the first and most likely culprit is a clogged ignition system. Food scraps and even grease can sometimes wedge themselves in these systems and cause the stove to continuously click. Solution: Clean your ignition system!
The off-cycle clicking noise that a furnace makes when it is off is usually normal and nothing to be concerned about. It is caused by the contraction and expansion of the metal parts as the furnace cools down or heats up.
Gas fireplaces installed in tight, energy-efficient homes might suffer from insufficient oxygen levels to sustain the flame. Many units come with oxygen depletion sensors that monitor oxygen levels in the room. The sensor will automatically turn the fireplace off if the oxygen level drops below a safe threshold.
A gas fireplace that won't stay lit is often caused by a faulty thermocouple, an insufficient gas supply, or a blocked pilot light. Regular cleaning and inspections can often help.
Once you've located the thermocouple, do a visual inspection. You're looking for a few things. The first is signs of contamination on the tube, which can include discoloration, cracks, or pinholes. Next, check the wiring for any signs of wear or corrosion like missing insulation or bare wire.
Check the gas and gas line: One of the first and simplest things to check is the gas line. If there is damage to the line, not only could it be unsafe and should be addressed immediately, but it may simply be the lack of gas to your unit that's causing the shut off. Also take this time to ensure you're not out of gas.
Clean the thermocouple - using the emery cloth sandpaper, sand the ends of the thermocouple and then give it a finishing touch with the lint-free cloth. Hopefully, you can get to the ends of the thermocouple without having to detach it from the assembly, but you may have to do that.
A dirty or corroded flame sensor can cause your furnace to keep shutting off unexpectedly. The flame sensor detects if the furnace's burner is lit, and if it doesn't register the flame, it will shut off the gas valve to prevent a gas leak.
So you've checked your pilot light and even reset it, but still, it wont stay lit. This can be an indication that your fireplace thermocouple is either bad or worn out. However, if your pilot is lit but the gas fireplace isn't, then there's probably a problem with your thermopile.
Any issues with the gas valve that supplies that gas to the flame, whether it be dirty or malfunctioning, can result in that flame going out. It's also possible that your gas supply has run low or out entirely, which will also cause the flame to blow out.
An igniter is one of the most critical parts of any gas stove because this is what switches on the fire on a stove. However, when the igniter gets damaged, it makes different sounds, and a popping sound is one of them. In addition to the damaged igniter, the damaged igniter wire could also be the reason behind it.
A malfunctioning fan within the motor could result in vibrations and clicks while running. Another possibility is that the back panel of the fireplace has become damaged. Check for dents or other forms of damage that might be affecting the blower motor's function.
A thermo couple is a sensor device that detects heat and permits the pilot light to stay lit. One of these devices could have gone bad or may have shorted out, causing your fireplace to turn shut down or turn back on at random.
