Why does my gas fire pit flame keep going out?
A gas fire pit that keeps going out usually traces to one of a few causes — wind blowing the flame off the burner, a dirty or spider-clogged burner, low gas pressure or a nearly-empty propane tank, or a failing thermocouple that stops proving the flame. On electronic-ignition pits, a weak igniter or flame sensor can do the same thing.
Start with the obvious
Before anything else, rule out the simple stuff you can check safely: is the propane tank low, is the supply valve fully open, and is wind knocking the flame around? A tank running toward empty — or a cold one on a winter night — can't push enough pressure to hold a steady flame. If it drops out every time a breeze picks up, that's a wind problem a glass guard solves, not a fault in the pit.
The spiders-and-dust classic
The one we see most, especially on a pit that sat quiet all summer, is a clogged burner. Spiders love to nest in burner tubes and orifices over the off-season, and dust and debris block the ports. The flame starves for gas, burns weak, and drops out. It's the same thing that clogs the pilot on an indoor fireplace every fall here in the mountains — and it's exactly why an annual cleaning before the season keeps a pit reliable.
When it's a job for us
If the fuel and wind check out, the cause is usually inside the gas train — a thermocouple or flame sensor that's no longer proving the flame, a pressure or regulator issue, or a burner that needs cleaning and re-tuning. That's licensed gas work, not a DIY fix; we'll diagnose it and quote any repair upfront before we touch it, and most of the time it's an inexpensive part or a cleaning. The diagnostic visit is $125.
