I have the fridge cited above; it has an icemaker IM115 Ad-18. Started making less ice over last week. I just blew out the water supply line, it was clear. Re-connected the line, disconnected plastic line that feeds icemaker at top. Turned water on, nothing. What looks like 2 plastic devices between water supply and icemaker. Checked voltage from fridge...nothing; arm is down so it should be "calling" for water?
