Ice Dispenser Rear Helix

Unplugged refrigerator. Removed cardboard cover, vacuumed lint from coils and equipment area. Removed dual valves and labeled the four electrical leads with masking tape. Cut off the end of water lines to dispenser and ice maker to remove threaded connections (New are simply push on). The water leads are of different diameters, so there is no confusion.
Decided to replace water line at the same time so bought a plastic replacement for less than $10, removed old copper line and replaced it with new. (Original plumber used a custom made line with a smaller diameter and this may have contributed to the low flow).
Connected all lines and wires (had to use adapter supplied with valve for two of the leads which are of different connector widths than original) and secured valve and back panel. Had to bedn the valve mounting plate somewhat to allow it to fit (this is also a little different from the original).
After installation, it takes a little time to refill the lines until proper flow is established both at the dispenser and the icemaker.
Replacing the Helix took completely disassembling the ice drawer, Take your tiime in doing this as there are many parts that fit in only one precise way. This helix replacement took about 20 minutes total.
