Abstract: An icemaker including an icemaker control module comprises components including an insert molded circuit board assembly, a motor assembly, an ice level sensing system using a bail arm or a paddle, and a water fill system. Lance features in the circuit board connect switch and motor leads. The thermostat, ground member, and heater of the icemaker electrically couple to the insert molded circuit board when the icemaker control module is joined to the ice maker. Energy may be conserved by pausing rotation and turning off the heater.

Abstract: A wrist pin for use with a piston of a refrigeration compressor unit, wherein the wrist pin is to be mounted on a piston and non-rotatively affixed thereto, the pin having a longitudinal axis, a round cross-section and a uniform diameter over substantially its entire length to provide a peripheral journal surface adapted to be mounted within and juxtaposed the bearing surface of a wrist pin bore of a connecting rod for rocking motion within the bore, one or more oil transport grooves in the journal surface circumscribing the same within a longitudinally central region thereof, a generally longitudinally extending recess in the journal surface extending across the one or more grooves and to either side thereof within the region, the region of the journal surface being dimensioned to lie totally within the wrist pin bore of the connecting rod, the recess laterally encompassing an arc angle of from about 6.degree. to about 30.degree..
