Alpay for Model Number MDC4650AWW sorry it took me long to respond to your answer. I checked the continuity for #26 and #14. I upload the bottom image here http://tinypic.com/r/20b1h5z/6 . i put letters on the connections. a and b are from thermostat which is AP4114820 and c , d are for AP4452252, heater. I checked a-c,a-d even a-b and getting buzz so does it mean all working? then i plugged in but as before no lights no power. i see the power comes to board, door latch, if i open the door latch voltage drops to 6-7 volts on board if i lock it comes up to 120V. that means door latch is also working. i replaced the board before with AP4114077. what else do you guys suggest,could it be the front display where the buttons and lights? , could there be something wrong with the belt cable comes from the board to front panel? how can I overwrite or test the front panel? i don't want to take it to service because i am sure it will cost same as a new dishwasher. :) So i really appreciate if you give me more points to troubleshoot. Thanks.
Answer Hello Alpay. If the control board is new, and the unit still does not work, it sounds like the control panel 6-919090 is bad and will need to be replaced on the unit. Read More... Answered by AppliancePartsPros.com | Tuesday, June 12, 2012
