Peggy for Model Number jvm1790owk01 The knob turns freely but doesn't do anything. Can I replace the (Pwb(pcb) Asm Sub Part Number: AP3883436 Made by GE) part by myself or is it something a professional has to do?
Answer Hello Peggy. These are not hard to replace. Unplug the unit and remove the two screws in the top of the microwave securing the grill. Remove the grill and open the door and remove the screw securing the control panel in place. Pull out the control panel and remove the control board from the panel. Reinstall with the new control board WB27X10866 in reverse order. Make sure the wires are installed on the new control board the way they come off the old one. Hope this helps. Read More...
