Lights in fridge and control unit LEDs are out, now icemaker has stopped working. Ordered and replaced fridge control unit without any change in problems listed.

Found your website yesterday and have completed the following checks:
All "3" bulbs are good.
Power to all "3" light sockets when all bulbs are removed.
Light switch has power and appears good.
Inspected control board in the white box at the lower back of fridge. Looks ok don't see burn or bad spot on either side of the board.
If I remove all "3" bulbs the control unit LEDs light up and displays temp number setting.
Add any "1" of the "3" bulbs back LED lights go out and no power to the other "2" light sockets.

Should I just replace the control board?
If the control board is bad could that be the reason for the icemaker not working or should we test the icemaker with a jump wire?

Thank you in advance for your help:)

Outlet is good. Fridge and freezer (light works in freezer) work good other than stated problems. Good power coming to the icemaker at connection but when we checked the module voltage with a meter (Test points L-N) there was 0 volts....no power.

Now thinking it must be a bad control board causing the problems with the lights in the fridge and control unit LEDs.

Plus now looks like the icemaker is bad unless the control board has anything to do with the icemaker too.
