No frost at all. noise started last night - eventually stopped after lifted ice maker lever . not sure this is related - had suspected the water valve but as I noted the noise/vibration is not coming from the bottom of the refrigerator where I believe the water valve/solenoid is.
okay since you lifted the arm on the ice maker it stopped and hasn't come back ?
So far - no more noise. The noise is really loud when it happens - like a fan with a bad bearing -but it starts suddenly. I am thinking it may be realated to the ice maker water fill because when I was moving the refirgerator out to check the location of the noise and subsequently opened the freezer, there was water dripping from the fill area indicating that it had just refilled? Note the automatic ice dispenser in the door stopped working a year ago or so - we just open the freezer and retrieve ice from the bucket
Okay then if the noise goes away with the ice maker off its the ice maker. Inside there are gears, The main gear is most likely stripped. this does happen but before replacing the ice maker remove it and see if the fingers are jammed with ice . could be a cube stuck in it. if not replace the ice maker.

Ice maker. click that blue link to order.
okay as I said the noise seems to stop when i lift the IM lever but when I pulled the refirigerator out, the noise and vibration was distinctly coming from an area not really close to the ice maker - the location was roughly 3 feet off the ground and all the way to the rigth as viewed from the back of the unit. Also the noise is much louder with the freezer door open than the refrigerator - but again does not seem to be coming from the ice maker itself. I really don't have time to take everything apart tonight - was hoping to get some idea of a possible part to replace - and order/pick up prior to taking everything apart :) Am I right in thinking the water valve/solenoid would be toward the bottom of the unit?
OK - I was really thinking the ice maker was coincidental. We have a couple pretty good appliance parts places here in Charleston I'll check with to see if I can get it locally - if not the link you sent looks great and a pretty simple repair. Thanks
