I have a Janome machine. My thread cutter is not cutting thread at all and I wondered if you can replace those. Are there blades in there that can be replaced?

I have a 2 wk old Janome and I love the thread cutter, I'm sure it's a replaceable blade but probably a service tech will have to change it.

I would think that it would be replaceable.

My instruction booklet doesn't mention that part at all....!!!! Probably something they have to do in the shop.

I have a viking and mine can be replaced. It had to send it out to be serviced though.

You can call the Janome headquarters and ask them. Their contact numbers link is:

Yes, but I think they have to be done when you have it serviced.

It could be there is a piece of lint or thread caught up in there causing the cutter not to work. Clean it out really good and see if that works. That is what was causing mine not to work.

Yes your local Janome dealer will have the replacement cutters. Its not all that expensive to replace. Before doing that run some waxed dental floss through yours and make sure its just not a piece of lint that is clogging it.

Excellent tip!
