I have the basic Leisure Bay (Balboa) 4 button spa side control (blower, light, pump, temp). It is working just fine, but the LED temperature display, as well as the heater light indicator have gone out. I noticed a small cut in the 8-connector phone line cord, that has gone half way through 1 connector, so i assume this is the culprit. Repairing this cut doesnt seem to have done the trick. Is it possible to just replace the cord to solve this problem, or do i need to order a new spa side controller? Also, if i need to order a new spa side controller, are the newer models with seperate up and down temp buttons compatable? (Specifically I am thinking about the Balboa 51057)

Thanks for the input!
