Smart Soldering Iron cools down immediately after reaching target temperature with no error codes

Thanks for the detailed rundown. You've already worked through a lot here, firmware, factory reset, power sources, the switch, and the idle and sleep timers, so you've covered the usual suspects.

The one thing I don't see on your list is trying a different tip. You've reseated the same tip a few times, but since the tip carries the heater and temperature sensor, swapping in a different one is the cleanest way to figure out where the problem actually is. If a known-good tip works fine, the original tip was the issue. If the cooldown still happens with a different tip, that points away from the tip and toward the iron itself.

So the easiest next step, given everything you've already tried: do you have a spare or second tip you can test with?

If you want something to reference while you're at it, we've got a guide on checking the tip and its connection. Heads up that it's framed around a disconnect error you're not getting, so feel free to skip past that part and just use the tip-checking steps.

If you don't have another tip on hand to test with, the best next step is to reach out to our Customer Support team, so they can take a closer look and walk you through the options from there.

Give the tip swap a shot and let me know what you find.
