Customer Questions and Answers for Icemaker by Frigidaire

Peter, You do not need to remove the ice maker, to adjust the water level, and yes the " little translucent knob" has to be removed. here are the instructions " The water fill can be adjusted without removing the ice maker cover. To adjust the fill size, remove the small round plug next to the On/Off Switch. Insert a #2 Phillips screwdriver into the hole about an inch or until it engages the Water Fill Adjustment Screw. Turn the screw clockwise to reduce the fill size; turn the screw counterclockwise to increase the fill size. One turn equals approx 20cc (0.68 oz). The correct fill is 85 to 95cc (2.75 to 3.25 oz). When a water valve is replaced, check the fill volume. " Be careful with the adjustments, a 1/2, and no more than 1 complete turn of the adjustment screw at a time, you can cause the icemaker to overflow if you're not careful.
