I repled the inlet wate valve; cheked that water coming in thru the tubes & water is coming in; dispenser thru door is dispensing water but no ice is being made. Found that that black wired part with a fan next to it is not turning on. Does this part affet the making of ice cubes? Cost to replace is high and I don't found on you online a video to repalce part?
Not sure the exact part that you are referring to as far as black wired piece next to the fan but if this is in the compressor area and the piece you are referring to is the compressor then yes if it is not coming on it would affect the operation of the icemaker and the unit itself would not work. Any other component would not cause the icemaker to not work if in the compressor area. You will want to let the icemaker cycle and if the icemaker is not making ice and the fill tube is clear then the issue would be a faulty icemaker.
