OEM Replacement Topside Control

Topsides typically do not interfere with the automatic operation of a hot tub. If you lose one buttons function that is usually the fault of the topside. Best method is to test the voltage being applied to the component that is not coming on when you press the button to make sure its not the component.

Historically other than above can be either topside failure or board failure. If you are not sure, call us and we can help.
