Nostalgia ric-100 retro series portable ice maker freezing system doesn't work.

Water line may be frozen, heat it with a hair dryer, see if water then flows.This can happen if aair flow to bottom of frig is blocked.

I have cleaned Manitowoc ice makers and their company specifically made an ice maker cleaner and sanitizer. Try a google search for this product.

Don't know if this will help: http://nostalgiaelectrics.com/product/ric100-retro-series-50s-style-automatic-ice-maker/

My Nostalgia Ice maker shows low water, but there is water up to the fill line.

Sounds like the intake line at the entrance to the refrigerator is plugged with lime residue. It has a needle valve in the center and will clog with foreign material, this can be cleaned out by forcing compressed air pressure backwards thru this connection to remove tiny particles inside.

Try to google for it but if unsuccessful you may have to resort to some sort of repair that will do the trick. May not look great but if it works, then.............................

Problem solved...
