Question

I have a combi which I have had for some years model carousel1 and the turn table has become slow and at times stops I have purchased another sharp--delivered yesterday modelR-959M-but if the old model can be repaired I would like to keep it as well. I have tried to contact a repairer without success and wondered if you can help me ? I live in Tyne and Wear region post code NE34 8PA
