SP300 - Heaters Not Working? HELP?!?!?!

[StickyLizard]

Hello all, I have a SP300 that has been working great. Last night I printed 2 jobs and on the third the machine panel says, "NOW HEATING...." the heaters are set ot 94 on both and both of them only get to 68?

I am not sure what happened. Has anyone else seen this? Could both of the heaters gone out? I have powered off and on the machine, I am at a loose, any help would be great.

Thanks,
Craig

OK, so it turned out to be a $ .38 fuse. The fuse is located on the main power supply board. It was seven screws on the back of the main unit and it was a simply tube fuse.

I agree, that is why I wanted to post a reply to my own posting.

I am glad it might help someone in the future.

Later
