My control panel display disappeared after water got into it. After taking it apart and drying it out the display is still not showing anything. The controller board (AP4343818) behind the display doesn't seem to get power. Does it get power from another controller board (AP4340863) or from the transformer? Which part should I try to replace?
The transformer feeds the user interface W10181439 so you will want to check for 24 vdc coming from the transformer to the control board. If there is 24 vac then the control board is bad and if not then check to make sure that the transformer is getting 120 vac to it. If not then check the thermal fuse to make sure that it is not blown. If thermal fuse is good but still no power then the control board EV9330-42 would be bad.

Answer Hello Steve. 1. Unplug range or disconnect power.
2. Pull the range forward so you can access
the two end cap screws.
3. To remove the electronic oven control
(EOC) assembly on slide-in models:
a) Remove the two screws from the sides
of the left and right end caps. b) Open the oven door and remove the
screws from the bottom of the
control panel. c) Pull out on the bottom of the control
panel, unclip the top edge from the
bracket, and rotate the control panel
forward so you can access the components. d) Disconnect the wire connectors from
the electronic oven control board at P1
and P2, and the ribbon cable connector
e) Remove the four screws from the electronic
oven control housing, and remove
the assembly from the control
panel. NOTE: The EOC boards and the
housing are replaced as an assembly. 1. Unplug range or disconnect power.
2. Pull the range out of its mounting location
so that you can access the rear of the unit.
3. Remove the control panel and rotate it
forward. 4. Remove the screws from the left and right
side trim, and then from the rear trim.
Remove the trim pieces from around the
cooktop glass. 5. Remove the cooktop glass brackets from
the left and right sides of the range. 6. Lift the rear of the cooktop glass off the
range, slide it out from under the front
control bracket, and remove it. REASSEMBLY NOTE: When you reinstall the
cooktop glass, be sure to keep the edges of the
glass against the rear and side support tabs.
