Refrigerator Ice Maker

My refrigerator also has as a through the door water dispenser like yours. Inside the refrigerator behind the bottom produce drawer there is a large coil of plastic tubing that is designed to pre-cool the water that is delivered to the door spigot.

You should check your refrigerator to see if it also has this same tubing arrangement. It is entirely possible that the previous owner of the refrigerator had left vegetables in the drawer for such a long time that they became severely spoiled and contaminated this tubing. Contamination could also have happened if spoiled food was on a shelf and decay liquids ran down the back wall into the tubing area. If the lower drawer was cracked and leaked out into the bottom of the refrigerator this problem could have been even worse.

If your refrigerator has this system I would highly recommend that you simply replace this coil of tubing with new.

Comment converted to answer ^{_{as per this suggestion}}

this GE document specifies a water pressure of 40-120 psi, for the ice maker to function properly.

• The water pressure must be between 40 and 120 psi.
• Pressures below 40 psi may cause a malfunction of the icemaker (i.e. producing hollow cubes or no ice production).

Which as BMitch points out in chat would mean the 1-2 gallon container would have to be about 100 ft. above the fridge.

Tester101: How tall would a 1/4" tube have to be, to produce 40 psi at the bottom if it was filled with water?

BMitch: if the link I found is correct, 93 feet
