163. Sequence of Electrical Circuit[a] When power switch is moved to “ON” position and flush switch to “ICE” position, water starts to be supplied
17[b] When reservoir has been filled, gear motor starts immediately.
18[c] Compressor starts about 60 sec. after gear motor starts.
19[d] Bin control operates, and about 6 sec. later, compressor and gear motor stopsimultaneously.
