Hi Matt,
Sorry to hear you are having these issues – from the description of the causes leading up to it this sounds like there may have been some significant hardware faults in that reactor. Whatever was wrong with it eventually led to a short in the circuit controlling the Blue LED (which incidentally is the most powerful of them) and now it is permanently on at maximum power (higher than intended by the software!)
I’d recommend getting in touch with Labmaker to tell them it came with a hardware fault and ask if they can replace it…
