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.
    1. 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.

3 HEAT SWITCH TEST (480V)

 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 AI4008 in WIRING DIAGRAMS for switch terminal locations.

  1. Lower the FRONT CONTROL PANEL to access 3 heat switch for a French Plate.

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:
    1. Standard oven – top and bottom elements.
    2. Hot Top element.
    3. French Plate element.
    4. Griddle element.
  2. Measure voltage at the heating element terminals and verify it against data plate voltage.
    1. 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.

2. 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.

3. 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

4. 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.

5. 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.

Controls power to the French Plates on 480V units. Provides approximately 100% of total available power per French Plate section with switch set to HI position, 50% at MED position, 25% at LO position, and 0% at the OFF position. The switch settings are: OFF, 1, 2 and 3.

Heating Elements Provides heat for the oven and Hot Top sections.

Infinite Switch Controls power to French Plate heaters and the top oven element for browning.

Depending on switch setting, provides a range of ON time from 7% to 100%. The switch settings are: HI, MED, LO, MED-LO and VERY-LO. On 480V units, the top oven element along with the bottom oven element are both controlled by the oven thermostat.

Indicator Lights
