You should see a new display on the machine now. It’s a three-pin locking connector with two very short loopbacks. On the back of the control panel, there’s a connector labelled “AA1”. Once those are off, usually pushing up will loosen the entire control panel assembly. Unscrew them, and remove trim and display cover. You will need, usually, a T-25 security bit, easily obtainable in a set for a few bucks at most hardware stores At the top of the Maytag machine you’ll see four screws holding the control panel on. Maytag Washers and dryers are essentially the same, card operated and coin-op are identical in their hardware and programming. The identifying features are green vacuum florescent display with a four-digit numerical display and six rectangular black buttons.
