PC BOARD 5304504070

Hello Mike, thank you for your question. We would suggest checking the connection between the touchpad, part number PS10066267, and the control board, part number PS11731941. The touchpad can be observed visually for physical damage. You may perform a continuity test to detect if the fault is in the control board. Calibrate the multimeter scale between zero and infinity for resistance. Touch the prongs of the multimeter with the terminals of the control board. Generally, when the meter shows a zero reading, it indicates that the path between two test leads has zero resistance. This confirms that the path is continuous and the board is not faulty. We hope this information helps!
