I have a five year old Kendal AC- 552 ceiling fan. Itw ill only run on high speed, not med. Or low. It is not the pull cord switch part, we replaced that, but the black box (the transformer) seems to be the problem. Can it be fixed or does it need to be replaced? If so, what stores sell that part?
Many thanks.
