My Whirlpool under counter ice maker is 8 years old. About once very year for most of this time it begins to have problems. The symptom is a surging sound which is caused by the pump trying to circulate water over the freezing plate but there is insufficient water in the reservoir. If I turn the machine off and immediately back on, the water fill function works and the ice maker will freeze and harvest ice normally and then dump the remaining water from the reservoir to begin the next cycle; however, it does not refill the reservoir so I must turn it off and back on to get it to continue working. If I just let the machine surge (i.e. pump run without water in the reservoir) for an extended period, it will eventually go on to the water fill portion of the cycle and produce and harvest some ice but this is so intermittent that it cannot keep up with ice demand (not to mention the annoyance of the continuous surging sound). When the machine was previously under an extended warrantee, technicians always had problems diagnosing and fixing the problem (although the symptoms were always the same) and just kept swapping parts until the problem was fixed. This included changing out the control board, water valve, thermister, thermostat, transformer and pump. More often than not the water valve seemed to be the final solution. I have recently purchased and replaced two water valves from you but this did not solve the problem. Since the machine will pump water from the reservoir and produce ice, it seems that the problem is the sequencing of the cycle to refill the reservoir so I am guessing the control board is most likely the faulty part but as these parts are all quite expensive, I am reluctant to "experiment" by swapping parts the way past technicians have done. What do you recommend?
ANSWER Hello William. Make sure the bin float is worrking properly. If so, you will need to replace the control board 2304016 in the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
