TL;DR
A control board is the printed circuit board that sequences an appliance's operation, reading sensors and switching power to motors, valves, heaters, and displays. In modern washers, ranges, refrigerators, and dishwashers it has replaced most mechanical timers, which means a single board failure can mimic a bad pump, igniter, or sensor.
What it means
A control board is the printed circuit board that sequences an appliance's operation, reading sensors and switching power to motors, valves, heaters, and displays. In modern washers, ranges, refrigerators, and dishwashers it has replaced most mechanical timers, which means a single board failure can mimic a bad pump, igniter, or sensor. Techs diagnose it last, by reading fault codes and verifying outputs with a meter, because boards are among the priciest parts and are frequently replaced on guesswork they did not deserve.
