Hello All,
I am currently working on 2 boards that make up the control portion of a hottub heater and am having no luck identifying a component on one of the boards that is blown and creating an open circuit between the pins that power the blower motor.
The component looks like a standard 78xx voltage regulator (same package style, black plastic square, metal heatsink with screw hole, 3 pin)
Upper left corner is marked - A
Upper right corner marked - 8
Across the middle - MA C15
Across the bottom - ON (in a circle, ON Semiconductor?) 0538
Any help identifying this part and/or what may have caused it to fail would be greatly appreciated
