Customer Questions and Answers for Control Board by Whirlpool

Jay, it is recommended that the end of cycle signal button is pressed for at least 5 seconds or until it beeps. If the control lock will not disengage, the user interface WP8558756 would need to be tested for proper operation. With the appliance unplugged, the end of cycle signal button can be tested for resistance at connection P3 from the wire at pin 12 (with red probe of meter) to the wire at pin 2 (with the black probe of meter). When the button is pressed, the resistance should start showing infinity and then move down to reading between 1 to 3.5MO. If this tests properly, the main control WP8546219 has failed. Unfortunately, the main control has been discontinued by the manufacturer and is no longer available.
