I noticed that a 3/8 amp 250v slow blow fuse had a 1/4 amp 250v slow blow fuse in its place. I will hopefully buy a replacement fuse for it tomorrow. This fuse was located in the bottom of the cabinet next to the power supply and was one of two fuses that related to the DMD. What happens when you put a fuse with an amp de******ion that doesn't match?

Thanks,

Usually bad things happen!!

But in this case the the fuse is underrated and so I imagine it is OK, just more likely to blow than the properly specced part.
