Yes, there are actually three fuses in the Janome 6600. They are very small and probably 3/4" in length. The one that went was for the step motor, therefore I got many error messages and no movement. I got it fixed for free because I had purchased the Sapphire 875 from the shop, otherwise, it would have been $150.00. Needless to say, I will definitely take both my machines there for servicing.
