Black conductor is hot. Red conductor is hot. Orange conductor is hot. Green conductor is ground. When the temperature in the control box reaches 120°F ± 3°F (48.9°C ± 1.7°C), the cooling fan thermostat will switch power to the control box cooling fan. The thermostat will interrupt power to the cooling fan when the control box temperature falls to 100°F ± 3°F (37°C ± 1.7°C). Electrical power is permanently supplied through six 50 A fuses to the normally open contacts of the heat relay. Power is also supplied, through the 10 Amp motor and control fuse, through the normally closed control box hi-limit thermostat, to the normally open oven power switch. Power is also supplied to the control box cooling fan thermostat. Closing the oven power switch supplies line voltage to the main fan motor. Closing the oven power switch also supplies line voltage to the heat circuit and to the primary of the oven control transformer. Closing the oven power switch supplies line voltage through the main fan air pressure switch, through the normally closed oven cavity hi-limit thermostat, to the oven control. Closing the oven power switch supplies line voltage to the primary of the control transformer and through the air pressure switch and oven cavity hi-limit, to the oven control. Secondary voltage, 24VAC, is supplied to the oven control. The oven control is set to desired temperature. The thermocouple will provide varying millivolts to the oven control. The oven control supplies line voltage to the heat contactor at intermittent intervals to maintain desired temperature. The display on the oven control will indicate when the heat contactor is energized. NOTE: The display also indicates oven temperature. Closing the oven power switch supplies line voltage to the conveyor motor and to the primary of the control transformer. Secondary voltage, 24VAC, is supplied to the oven control. Setting the oven control to the desired time outputs voltage, through a reversing switch, to the conveyor motor. NOTE: The conveyor system uses a hall effect sensor and magnet to prove operation of the conveyor motor. If the motor is not running, “BELT JAM” is indicated on the display.

If no voltage is present, trace wiring back to oven power switch. If voltage is present, check for 24VAC at transformer secondary. If there is primary voltage, but no secondary voltage, replace control transformer. Oven control Check for 24VAC supply to oven control. If no voltage is present, trace wiring back to control transformer. Check for supply voltage to oven control. If no voltage is present, trace wiring back to hi-limit thermostat. If voltage is present, check for a read-out on the display. If there is no read-out on the display, replace oven control. If there is a read-out on the display, set the oven control to maximum temperature (see installation operations manual for temperature adjustment). With the oven control at maximum temperature, check for supply voltage to the heat contactor. If there is voltage at the heat contactor, proceed to “Heat contactor “. If there is no voltage at the heat contactor, trace wiring back to the oven control. If there is no voltage output at the oven control, check the read-out on the oven control. If the oven control reads “PROBE FAIL” this indicates that the thermocouple has failed or become disconnected from the oven control Thermocouple Check to see that the thermocouple is securely connected to the oven control. If the thermocouple is connected to the oven control, and the display indicates “PROBE FAIL”, disconnect the thermocouple from the oven control and measure the resistance of the thermocouple. The thermocouple should read approx. 11Ω. If these readings are not achieved, replace the thermocouple. If these readings are correct, proceed. Oven control If the thermocouple checks good, but the oven control display indicates that there is a thermocouple failure, replace the oven control. If the oven control indicates a temperature reading, but the oven will not heat, proceed. Thermocouple WITH POWER ON AND THERMOCOUPLE ATTACHED TO THE OVEN CONTROL: Measure the DC millivolt output of the thermocouple. Refer to the thermocouple chart (located in the “Removal” section of the manual) for proper millivolt readings. If these readings are not achieved, replace thermocouple. Oven control If the thermocouple checks good, but there is no supply voltage output to the heat contactor, replace the oven control. If there is supply voltage output to the heat contactor, proceed. Heat contactor(s) Check for supply voltage to the heat contactor. If voltage is present, listen for contacts to open and close. Also check for opens or shorts in the operating coil. Replace heat contactor as needed. Thermal/overload of main fan The main fan motor is equipped with internal thermal motor protection and will cease to operate if overheating occurs. As the motor overheats and cool, this will cause the heating system to cycle on and off intermittently. Improper ventilation or lack of preventive maintenance may cause this problem. Also most of the problems listed under “Oven will not heat” can cause intermittent failure. Incoming power supply Check circuit breaker, reset if required. Check power plug to be sure it is firmly in receptacle. Measure incoming power, call power co. if required. Fuse, 10 Amp Check, replace if necessary.
