I'm assuming it's a thermostat failure - the JumpStarts are decent but cheap. I'd be surprised if it is a probe placement issue - I check probes every day, as I'm just paranoid that way.
And you're right, thank goodness! Many of my Ultratherms (I have no heat tape - just Ultratherms) do have the typical striped heat tape appearance - but in checking photos on the Bean Farm website, it looks like some of the Ultratherms are 'striped', while others are black. I don't know why this would be; I don't know the inner workings of heat tape/UTH. Obviously I didn't take note of that when I ordered this one, which was one of their larger models and meant to be shared between the two baby Boa tubs.
I was thrown off balance by the thermostat failure this morning, and once I was sure the baby Boas were OK, I was a bit upset thinking that one of my bigger, more expensive Ultratherms was ruined. Plus I didn't look forward to the enclosure juggling I'd have to do to make sure that the snakes still in tubs were all taken care of in terms of UTH.
Thanks for so patiently pointing out my silliness, lol. Though I am going to pull the trigger today on replacing those last couple of JumpStarts with Herpstats!
Here's a stripey Ultratherm. I'm not totally crazy!![]()
