LED Display

The Temperature display for my oven is very faint. I can only see the temperature of the ovens if I put my hands around it very close. The time looks just fine. But for some reason the LED display for oven temp is almost not even there?

I have already replace the following parts to no avail:

AP3043893 (8300440) Control panel assy w/membrane, switch blk
AP3598617 (8301848) Cntrl-elec

Any recommendations would be greatly appreciated!

Thanks in advance!

Looks like the parts listing is screwed up.
The Control board you list looks more like a relay board than a control board.
Did the control board you received have the display on it?

This may help if you do not already have it

If not then I would say that is what you need.

Sounds like it could be the transformer (Item 6 in Section 7) is no good.
The problem here is that the display is OK when it shows the time.
We cannot get actual board schematics but I would have thought that the drive for the display would be the same for time and temp.

I could not see the tag in the picture of the part very good but it looks like it should be putting out 24 volts AC.
