1) Remove thermostat knob. Maintain
thermostat setting during removal.
Fig. 35
3) Turn adjustment screw clockwise to
increase and counterclockwise to
decrease temperature.
NOTE: A 1/4 turn equals 35°F change.
6. Replace knob and repeat steps 3 to 5 until

INFINITE SWITCH TEST (208V/
240V)
Certain procedures in
this section require electrical test or
measurements while power is applied
to the machine. Exercise extreme
caution at all times and follow Arc Flash
procedures. If test points are not easily
accessible, disconnect power and
follow Lockout/Tagout procedures,
attach test equipment and reapply
power to test.
NOTE: Refer to AI4007 in WIRING DIAGRAMS for
switch terminal locations.
1. Lower the FRONT CONTROL PANEL to access
infinite switch for a French Plate.
A. If checking infinite switch for the oven,
remove OVEN CONTROL PANEL.
2. Connect a voltmeter to the output terminals H1
and H2.
3. Reconnect power to machine.
4. Turn knob to the desired setting.
5. Compare the percentage of ON time to OFF time.
NOTE: ±7.5% tolerance allowable.

HEATING ELEMENT TEST
Certain procedures in this section require electrical test or measurements while
power is applied to the machine. Exercise extreme caution at all times and follow Arc Flash
procedures. If test points are not easily accessible, disconnect power and follow Lockout/Tagout
procedures, attach test equipment and reapply power to test.
NOTE: 208/240V - The standard oven uses and infinite switch to control the top element for browning and a
thermostat to control the bottom element for oven heating. The thermostat supplies power to the infinite switch and
must be ON for the top element to heat.
NOTE: 480V only - The standard oven uses a single thermostat to control the top element for browning and the
bottom element for oven heating.
1. Set temperature control to the highest setting for the heating element to test:
A. Standard oven - top and bottom elements.
B. Hot Top element.
C. French Plate element.
D. Griddle element.
2. Measure voltage at the heating element terminals and verify it against data plate voltage.
A. If voltage is incorrect, see TROUBLESHOOTING to help determine the possible cause. If voltage is
correct, check current draw (amps) through the heating element lead wires.
NOTE: Checking current draw is preferred over a resistance check when a clamp on type amp meter is
available.
B. If current draw is correct then heating element is functioning properly. See HEATING ELEMENT
TABLE for proper values. If current draw is not correct, turn temperature control OFF and disconnect the
electrical supply to the range. On ranges with two ovens, each section will have its own supply power
connection.
C. Replace heating element for the range as outlined under the appropriate procedure listed below then
proceed to step 3:
1) OVEN HEATING ELEMENTS
2) HOT TOP
3) FRENCH PLATE
4) GRIDDLE HEATING ELEMENT
D. If unable to check current draw, a resistance check may indicate a malfunctioning element.
1) Disconnect electrical supply to the range. On ranges with two ovens, each section will have its own
supply power connection.
2) Remove lead wires from the heating element and check resistance (ohms). See HEATING
ELEMENT TABLE for proper values.
E. If resistance is not correct, replace heating element for the range as outlined under the appropriate
procedure listed in step 2C.
3. Check for proper operation.
