Fridge/freezer works fine but when in-door ice maker is switched on a loud "clacking" noise starts within 1 - 30 minutes and doesn't stop. It seems to come from the yellow/orange relay on the main circuit board (lower left back).
The optics seem to pass the diagnostics, there is water in the ice maker, I've been following the current "Whirlpool ice maker woes" thread and my machine looks identical except there is no manual switch on the Infra-red receiver board.
Following a defrost and re-start the ice maker will sometimes make one load of ice before the "clacking" noises start again.
Any ideas gratefully received. Anyone know where I can get a full circuit diagram for this model? Thanks
