Hi Carrie,
this is not a machine knitting forum to post such questions.
However I will help you out.
You don’t have to buy a new carriage for your knitter.
If the MC button blocks, just take a piece of cotton, some alcohol and use it like dental floss to clean around all the buttons. Try the MC button again if it moves. You can also drop one or two drops oil under the MC button and between the metal part. Try moving the button many times till it works again. In most of the cases this is an easy solution.
However it could be that the carriage is full of fluff. In that case remove the handle and the plastic cover to clean it inside. You can find service manuals here for the information how to remove the parts;

If you look for another carriage try to find a KH860 or higher number. There are slight differences between the carriages, some have the option to knit intarsia with the K-carriage.
Hope it will help
Lydia
