Overload Check; Compressor Check; Capacitor Check - Cornelius WCC 2001 QT-R Service Manual

Continuous Flow Icemaker Service Manual
O C
VERLOAD HECK
Using a volt–ohmmeter check the continuity
across the overload, contact #1 and #3. If none,
wait for unit to cool down and try again. If still no
continuity, the overload protector is defective
and should be replaced.
C C
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.
