I have a Maytag dishwasher, which suddenly stopped working and found out the power supply wire nut connection came loose. Reconnected the loose cable but now there is power to just the right side of the membrane control panel. I tested the two micro switches that are activated when the door is closed, but the left side switch is not getting any power. The right side switch has power to it.

I looked at all of the wires and none look damaged. Could a quick fix be as simple as feeding power to the micro switch from another source. I presume something is wrong with the printed circuit board that is failing to provide power to the switch?
