Re: whirlpool S20B RWW20-A/G ICE MAKER
Lift the flap up where the actual ice maker is, feel to see if that black rubber pipe on the roof is frozen, if the waters only just been connected and the ice maker has never worked since you conencted it, i doubt this would be the case.
Is the little red light flashing on the left hand side?
Is the ice maker switched on (silly question!)
