If you get dust in the pilot assembly and the pilot needs to be cleaned out, it produces a “lazy” flame, which will be disturbed by the draught of the main burners. The flame lifts away from the thermocouple and causes the temperature on the tip of the thermocouple to drop. This, in turn, makes the gas valve shut off.
Why does my fire pit keep going out?
Another common reason why campfires go out is because the wood is wet. In order for wood to light — and stay lit — it needs to be dry. If it’s too dry, combustion won’t happen; thus, the campfire will likely go out. If you’re camping in an area where there’s little-to-no dry wood, consider bringing your own.
Why does my fire table won’t stay lit?
When the pilot won’t light, you can often trace the problem to a lack of propane, either because the tank is empty or a valve is closed. If the pilot won’t stay lit, the problem is usually related to the thermocouple, a heat-sensitive electrode that signals the gas valve to stay open when the pilot is on.
How do you bypass a thermocouple on a fire pit?
To bypass the thermocouple:
- Move the tilts switch wire aside.
- Remove your thermocouple from the heater using an 8mm wrench.
- Pull the valve housing aside using your 13mm socket wrench. …
- Remove the valve using your pliers. …
- Put your thermocouple back into position.
What is a thermocouple on a fire pit?
Thermocouple. Some fire pits have a thermocouple which senses the heat from the pilot light flame. That signals the gas valve to stay open when the pilot is on. Tighten all connections at the thermocouple and gas valve.
How do you tighten a thermocouple on a nut?
To adjust the thermocouple, you must tighten the thermocouple nut with a wrench. Take care not to apply too much pressure to the nut — just tighten it slightly. Then try lighting the pilot. If the pilot won’t stay lit, replace the thermocouple with a new one of the same type.
How long do fire pits last?
The average gas fire pit will last from 3 to 6 hours on a 20 lb. propane tank. Depending on your fire pit BTU rating a tank can last you as long as 9 hours, or as little as 1-1/2 hours. A 20 pound propane tank contains approximately 430,000 BTU’s.
How much does it cost to replace thermocouple?
The thermocouple is an apparatus that senses whether the pilot light is lit and triggers the gas control valve. Repairs typically cost about $150 to have it done professionally, though a new thermocouple itself only costs about $20 on average.
Can you clean a thermocouple?
The best way to clean your thermocouple is to use either a piece of steel wool or the coarse side of a sponge to gently clean off any soot or other remnants. You can use a pencil eraser to clean between the threads of the screw that connects the thermocouple to the control valve of your system.
