Customer Questions and Answers for Electronic Control Board by Whirlpool

Hello Eddy, You should first check voltage to the board through the fuse WPW10291948. If there is no voltage going to the board from the fuse, the fuse will be all you need to correct the issue. If the voltage is going to the board, you need to check for 120Vac going into the low voltage transformer at terminals P16-5 to terminal P16-7. If testing between these two terminals shows you the 120Vac, you need to read the output voltage from this low voltage transformer. This will be i the neighborhood of 20Vdc voltage. Note the dc voltage has to be read on the dc scale of the meter. This reading will be taken from terminal P16-2 to terminal P16-3. If this voltage isn't present, you will need to replace the low voltage transformer. If it is present, you will need to replace the main control board WPW10438751. The sister board WP8301848, as the manufacturer calls it, has nothing to do with the issue you are experiencing. It is the self-clean board responsible for sending voltage to the door lock assemblies. This is its' only function, so you should just be careful with it and move it to the new assembly if need be.
