6300/6310 Treadmill Electronics Repair Manual – Testing
Key Operation
Key circuits have continuity when keys are pressed down and don’t have continuity when not pressed down.
Key signals travel from the keypad via the wire connector to the display board. A sign of a possible key
malfunction, (or a wire break or short) occurs when the treadmill acts as if a key has been pressed when no
key was pressed, or the treadmill does not react when a key has been pressed.
