C24EO SERIES STEAMER - SERVICE PROCEDURES AND ADJUSTMENTS
HEATING ELEMENT TEST
The heating element assembly contains elements
molded into a cast aluminum block. 3 pan units have
6 elements and 5 pan units have 3 elements. See
wiring diagrams.
1. Turn cooking mode switch to constant.
2. Measure voltage at heating element terminals on
contactors and verify it against data plate
voltage.
NOTE: For 480V units, element voltage is 277V.
A. If voltage is incorrect, find the source of the
problem.
B. If voltage is correct, check current draw
(amps) through the heating element lead
wires.
NOTE: This method is preferred over a
resistance check when a clamp on type amp
meter is available.
1) If current draw is correct then heating
element is functioning properly. See
table below for proper values.
2) If current draw is not correct, turn
cooking mode switch to OFF and
disconnect the electrical supply.
a. Replace heating element assembly
then proceed to step 3.
C. If unable to check current draw, a resistance
check may indicate a malfunctioning
element.
1) Turn the cooking mode switch to OFF
and disconnect the electrical supply.
2) Remove the lead wires from the heating
element and check resistance (ohms).
See table below for proper values.
3. Check for proper operation.

NOTES:
1. Values in the table are nominal. Tolerance
is +5/-10%.
2. 3 pan 208V units use three 2003W
elements and three 664W elements.
3. 3 pan 208/240V units share the same
element assembly block. 240V units use
only the three 2003W-marked elements
(2667W actual).
4. Resistance values (ohms) are @ 77
