Diode
Used to drop the 240v input to a 115v supply voltage to the mould heater.
TCO – Thermal Cut-Out
The thermal cut-out is a one time, limit fuse used as a safety device. It is located under the mounting
plate, in the head of the ice maker, between the thermostat and the wire connector. If the thermal
cut-out opens, the cause of failure must be found and corrected before replacing the TCO.
Timing Cam and Coupler
Three separate cams are combined in one moulded Delrin part.
• Inner cam-not used.
• Centre cam operates the holding switch.
• Outer cam operates the water valve switch.
One cam end is attached to a large timing gear. The other cam end is coupled to the ejector.
Timing Gear
This large moulded plastic gear is driven by the motor and, in turn, rotates the cam and ejector. A
“D” shaped hole in the gear fits over the timing cam hub. Spacer tabs on the backside of the gear
prevent the gear from binding on the mounting plate.
Motor
A low wattage, stall-type motor drives the timing gear. This gear turns the timing cam and ejector
blades approximately one revolution every three minutes (1/3 rpm)
Fill Trough
The fill trough is moulded Nylon. It supports the inlet tube and directs the water into the mould.
Wiring
A four pin connector connects the ice maker wiring to the cabinet wiring harness. The ice maker
assembly is wired across active and will harvest in either the refrigeration or defrost cycles. (See
Figure D3)
