Frigidaire FFHD2250TS1:

All of a sudden I cannot select the water "button" no matter how I try to touch it, it is not responsive same for the cubed ice option, though this will sometimes work, just with no consistency.

I've checked to make sure it isn't locked etc. All cooling/freezing works, ice dispense correctly (just only crushed). Water filter and hookups are fine and functioning properly.

I'm assuming I need to replace the control board? Any other parts that will be needed?

Many thanks to anyone who can help!
