3.If the circuit board is to be replaced, return it in the packaging in which you received your replacement circuit board.
4.Install the circuit board with the component side away from the door. Slide into guides and push firmly until it is seated in the circuit board jack.
5.Apply power to the unit and switch on. If digital panel is blank, it is possible the circuit board is not seated properly. Disconnect power and repeat Step 4.
