Comment on ultrasonic cleaner -- should I try to fix it?

Does it have heat? Might still be useful as a soaking only bath for things that just need to soak. But you might wanna crack it open and see of its just a bad capacitor that popped.

No, in fact the cheap thing is allergic to heat. The manual says it’s important to fill with /cold/ water. And the running time is restricted to like 4 min. If I run two cycles, the water gets a little warm despite (apparently) having no heating element. The manual also says not to run more than 2 cycles. So it seems the thing is sensitive to heat and the water functions to keep the ultrasonic generator cool, which makes it a bit sucky. I know pro jewelers who have industrial cleaners that have heating elements to deliberately make the liquid very hot.

My cheap vevor sonic cleaner has heat. This thing sounds like trash, time for a upgrade.

I saw a video at some point on how to build an ultrasonic by epoxying an u/s generator to the bottom of a metal tub. Many adhesives fail when a surface gets sufficiently hot. I haven’t opened it up yet but I imagine they used some kind of adhesive, as opposed to welding it. It would be interesting to know if your cleaner uses glue or welding to fasten the u/s generator.
