I have a 2000w, 240 -> 120v transformer. It's a Bronson++ AVT 2000, with a continuous max wattage of 1200w, meaning if running for over 30 minutes it should be under 1200. I ran a 1500w blender on it for roughly 5 minutes at a time which I was told has a soft start on it to avoid initial power surges so I figured it would be fine to use with.
Whatever the case, the transformer doesn't turn on anymore. It has a fuse, and I checked the fuse for continuity and it seems ok. It came with replacement fuses, I threw in one of those and still no go. The transformer worked fine the last time I used it and then the next time it just wouldn't turn on. I have reason to believe the connection I was using it on at the time may not have been grounded properly.
So what happened? I thought transformers were pretty simple things and if something were to blow it would be the fuse. How would you debug what created the problem, and is it possible to fix them as an amateur or is it not worth the risk?

Well, the rule with all things electrical is, they work right up until they don't. With a small transformer like that, it is likely if it overloaded it could burn a wire in half thus failing open.
Apparently, you have a basic voltage tester so you can test for continuity (or resistance) on the primary side (240v) of the transformer, and test the secondary side (120v). It is possible some part of the external wiring has opened and could be repaired. If either the primary or secondary are open, internal to the transformer, then you could replace the transformer. If this is cost prohibitive then, unfortunately, you may have to buy a new one.
Good luck!
