Very hot heated bed MOFSET
I'm new to the necessities of maintaining my Prusa and have recently done a lot of overdue work on it. One problem I kept having was the heated bed would simply refuse to come on. I found that the positive wire that attache to the heated bed MOFSET seemed to have some melted plastic on it which I cleaned off and after the the bed heated normally for awhile. Then I started having the same problem and I noticed that the wire had come loose again. I secured it once more but then noticed how hot the MOFSET was getting and I'm wondering if this is normal or has something happened that I need to fix. The MOFSET was too hot to touch.
Any insight or advice is appreciated.
Cheers,
James
