On my model 95 U-Line Ice Maker, it NEVER makes ice the 1st I turn it on, NEVER!!!! The solution is buried deep in the manual trouble shooting. It says to turn the thermostat UP slightly. Once you hear the tinkle of ice cube making, turn it back down to where it was. Kind of counter intuitive but works every time for me.
It is a replacement ice-maker compressor. The original U-Line was an R12 Gas model and is no longer available. The new compressor assembly is available from Air & Water, Inc., at $369. The unit is model A1-500SS. Phone 1.800.734-0405 or 714.421.4328. FAX 714.200.0665. Their address is 100 South Linwood Ave., Building B, Santa Ana, CA 92705. One has to shave off approximately 1/4" on one of the vertical frames.
