Ice maker and crusher works fine. Water does not come out when glass etc activates switch. I pulled off back of frig, pulled line off and no water comes from blue side(red goes to ice maker). Tested the DC voltage. Sometimes 250mv and sometimes 1.5v. My guess is the powersource which might be the control panel on front (about $50).. or the water pump thing in the back (splits the refrig water and ice maker water) (about $35). Question: what is the voltage supposed to be, and is there other possibilites. -brian
