Some potters are equipment enthusiasts. Like George Costanza, who always wanted to be a Civil War buff, I always wanted to be a burner nerd. But UGH. In reality, I want a burner that will just quietly keep doing its thing without any attention from me. Note to readers, if you want this kind of burner, use Venturis! These power burners are for the birds. Can't complain about the results, and they are for sure more efficient, but something goes wrong with these friggin' things a couple times a year, which is way more than I want to think about burners. I'm trying to look on the bright side - "I'm learning so much!" - but learning about stuff that bores you is just a slog.
But slog I must.
When I went to light the burner for Sunday's bisque, the baso valve failed. This seemd very odd to me because in my experience, basos can go for decades. This one is barely four years old. With the help of my friend Dennis Chouinard, who takes apart burners for fun, we opened up the valve & discovered one of the wires was interfering with the action if the spring inside - pretty simple fix with a pair of needle nose pliers. It also explained why the button on that valve had always been slow to pop up. Did that fix work? WELL I DON'T KNOW, DO I?? Because in all the transport & handling, we somehow effed up the function of the solenoid valve. If the baso valve is a dandelion, the solenoid is an orchid or a hybrid tea rose - look at it wrong & it gives up the ghost. I know potters who modify their burners not to need a solenoid for this exact reason. I'm not going to do that, because it's a safety feature - its job is to sense if the power goes out, because if the blowers aren't working, the propane could ignite in the plumbing, potentially causing an explosion. If you are the sort of person who hangs out right beside the kiln for the entire firing, this is probably a reasonable thing to do! I am not: I candle overnight, when I'm obviously asleep, and sometimes I take a nap during the long climbing period between ^05 & ^6. So, while I fucking hate the solenoid (pretty sure that feeling is mutual), I wouldn't fire without it.

Solenoids vs basos |
Luckily I have a spare solenoid handy. Repairs are less intimidating to me once the money is already spent! My plan today is to separate the electronic part of the solenoid from the mechanical part, see if I can observe any obvious problems (lol but you never know! See baso valve, above.) If I can see & fix what's wrong, awesome! If I can't, I will replace the old electronic part with the new one. If that doesn't fix it, well, that's why I've got Dennis on speed dial.
It's been kind of a trying couple of weeks. No pressure but if you want to make me smile (for free!) you could subscribe to my patreon page. (Seriously, though, no pressure. I post a lot there so if getting notices in your email is going to annoy you, maybe you shouldn't. Yes I suck at sales.)
