The water dispenser on my refridgerator does not work. I can't figure out how to access the switch and/or pump behind the front panel (at least that's where I assume it is located).

There is a clicking sound that makes me think the switch is OK. I assume there is a pump that the switch activates to presurize the water flow but that is only a guess. It quit abruptly so I think it is electrical/mecahnical vs. a plugged supply line or something.

Help! Thanks
