Check to ensure the temperature at the ice maker is below 8°f. The icemaker will not cycle until it reaches below that temperature.

The ice maker temp is at 27°. I have also replaced the main control board and now my lower freezer fan won’t stop running. I also don’t get water to the ice maker. I have replace the water inlet valve, water filter and ice tray assembly. I have ran both diagnostics on this and everything passes except for the ice maker temperature
