DIAGNOSTIC SERVICE MANUAL

DOMETIC® RM7030/RM7732 Refrigerators

11.8 ICE MAKER ASSEMBLY

It may be necessary to replace the entire ice maker assembly.

Disconnect power to the appliance. Disconnect the leads inside the ice maker unit. Check each wire for continuity to make sure the wiring is good before replacing the ice maker unit. If there is no continuity on any of these wires, replace or repair them as necessary and recheck the ice maker unit to determine whether the problem was in the wiring or the unit itself.

OPERATION

While the operation of the ice maker is fairly simple, an understanding of its cycle is necessary for the service technician to diagnose specific problems.

The following series of electrical schematics (on the following pages) will show a typical cycle, and the positions of various components during the cycle: the mold and its contents, the ejector, the shutoff arm and the storage bin.

NOTE: If you have difficulty in reading schematics and circuit diagrams, please enroll in a basic electrical course at your local school or college.
