Victor 884 Issues

[BHS Bucs]

Hi everyone -

We're a rookie team from Massachusetts - just the other day, we started having issues with one of our Victors. The students replaced it and things were fine for a bit - then the replacement stopped working. After quizzing the students working on electrical, what they can tell me is:

1. It didn't smell like burnt plastic.
2. None of the parts look melted.
3. The light no longer turns on.
4. The fan works fine.

We're puzzled (lack of experience is playing a role here!) - we've read about burning out Victors and shorting Victors on other threads... But we're not sure if that's what is happening here.

We did find some exposed wire that they have now taped, but I'm leery about putting in our last working one right now unless we can figure out what is wrong.

Thanks in advance for any thoughts!
