OMPRESSOR HECK
The resistance readings on the windings will be
between 0.25 to 10.00 ohms, a meter capable of these
low readings must be used.
1. Check between "C" and "R." Replace the compres-
sor if there is no continuity as the run windings are
open.
2. Check between "C" and "S." Replace the compres-
sor if there is no continuity as the start windings
are open.
3. Check between "C" and "R" or "S" and the shell of
the compressor. If there is continuity, replace the
compressor as the motor is grounded.
4. Check between screw terminal on the overload
and "C" on the compressor. Check and repair the
lead or connections if there is no continuity.

APACITOR HECK
1. Check or replace start capacitor, disconnect bleed resistor before checking for shorted capacitor.
2. Check or replace run capacitor (if supplied) check for shorted capacitor or either terminal grounded to case.

Your icemaker unit has several safety and control devices incorporated into its design.
!
WARNING:
None of the below described devices should ever be "bypassed" to allow the unit to function.
The safety and control system shut–off devices are:
1. Low water shut off reed switch located in icemaker float assembly. (Automatic reset type.)
2. Gearmotor thermal overload, manual reset type (red button on motor).
3. Compressor thermal overload, automatic reset type.
4. Anti–freeze relay and associated circuit. See wiring diagrams.
5. Main service switch located on top of the control box.
6. Bin Control.
7. High pressure cut out (water cooled only).
