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 (37.8°C ± 1.7°C). Power is permanently supplied through a 10 amp oven fuse to the normally open double pole oven fan switch. Closing the oven fan switch supplies line voltage to the main fan motor. Closing the main fan switch also supplies voltage to the cooling fan through the EMI Filter to the primary of the control transformer, the conveyor motor, and the burner system.

terminals C and NO. If voltage is present on one side
only, check for air tube blockage or misalignment. If
these are okay, adjust air pressure switch or replace if
necessary.
Terminals are normally closed, opens at 350°C (660°F).
If open, reset and test oven for proper operation. If
thermostat will not hold for maximum oven temperature,
and oven is not exceeding control setting, check for
proper location of capillary bulb in its spring holder. If
above checks are okay, replace hi-limit thermostat.
Check for proper voltage to the burner blower motor.
This can be checked at motor connecting plug terminal
7
2 and Neutral. If voltage is present, proceed with next
step, if not, wait 30 seconds, push reset button and try
to restart. If this fails, check wires from burner blower
motor to the ignition control. If the above checks okay,
replace ignition control. Burner blower motor Chec k for supply voltage to motor. WITH POWER OFF:
Turn blower wheel to check for locked rotor. If supply
voltage is present at motor connecting plug terminal 2

blower motor. Air pressure switch
(burner blower)
Check for proper supply voltage switching from “NC” to
“NO” on ignition control. Check for air pressure switch
adjustment, air tube blockage or misalignment. If these
adjustments fail, replace air pressure switch. Ignition control A pre-purge time of 30 to 60 seconds occurs after
burner blower motor starts. Check for high voltage
spark output from the ignition control. If there is no high
voltage spark output, check reset button for ignition
control. If there is still no high voltage output, replace
the ignition control. Igniter/sensor assembly Check this a s sembly for visible damage. Replace as
needed. If there is no visible damage, check for voltage
supply to igniter/sensor assembly. If there is voltage
supplied to the igniter/sensor, but there is no spark,
replace igniter/sensor assembly. Gas valve Gas valve should open as the ignition control generates
the high voltage spark. Place manometer on the
pressure tap fitting (located in the gas piping just prior
to the burner manifold) and check for gas pressure. If
valve does not open, check reset button on ignition
control, and all connections for tightness. If there is still
no gas pressure, remove the ignition control from the
gas valve. Check the coils of the gas valve for opens or
shorts. Readings should be as follows, V1 – 2.9K ohms
approx., V2 – 1.3K ohms approx. If these readings are
not achieved, replace gas valve. If these readings are
achieved, replace ignition control. Flame will not stay on Flame sensor To check for flame sensor operation, connect a digital
multimeter (capable of measuring DC microamps)
between the flame sensor wire and the flame sensor
connection on the ignition control. Sensor current is to
be 0.9 microamps, minimum. If these readings are not
achieved, replace igniter/sensor assembly. Also check
for any type of damage to flame sensor wire and
connections.
NOTE: The DC microamp test must be conducted with
the oven in low flame (bypass) operation. Power supply Set the temperature to the lowest temperature setting.
If there is sufficient microamp current, but the flame will
not stay lit, check for proper polarity of the power
supply. Ignition control If there is sufficient microamp current, and there is
proper polarity of the power supply, but the burner will
not stay lit, check the reset button on the ignition
control. If the above test is okay, replace the ignition
control. NOTE: Flame should be on at
this time Low flame is on, but no main flame
Control transformer Check for supply voltage to the primary of control
transformer. If no voltage is present, trace wiring back to oven fan switch. If voltage is present, check for

24VAC at transformer secondary. If there is primary voltage, but no secondary voltage, replace control transformer.
Conveyor motor Check for supply voltage to the conveyor motor at wire
#6 to neutral. If no voltage is present, trace wiring back to the oven fan switch. If voltage is present, but the motor will not run, check the motor windings for opens or shorts. If any of the above fail, replace the conveyor motor.
Capacitor, conveyor motor Check for shorts or grounds. Replace capacitor as
needed. WARNING: Capacitor has a stored charge, discharge before testing.
Switch, conveyor reversing Check continuity between switch terminals. Replace
switch as needed.
Oven control If there is voltage supplied to the motor, and the motor,
capacitor and reversing switch check good, replace the
oven control. Conveyor motor runs, but there is no speed display Oven control Check for output voltage from oven control to hall effect

check for a frequency output from the hall effect
sensor. Measure frequency across the yellow and white
wires in the motor connector. Frequency reading

transformer. If no voltage is present, trace wiring back
to oven fan switch. If voltage is present, check for
24VAC at transformer secondary. If there is primary
voltage, but no secondary voltage, replace control
transformer. Air pressure switch Check air switch terminals for supply voltage to
terminals “NO” and “COM”. If voltage is present on one
side only, check for air tube blockage or misalignment.
If these are okay, adjust air pressure switch or replace if
necessary. 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 oven fan switch. If voltage
is present, check for a read-out on the display. If there
is no read-out on the oven display, replace oven
display. If there is a read-out on the oven control, set
the control to maximum temperature (see Installation
operation manual for temperature adjustment). With the
control at maximum temperature, check for supply
voltage to the mercury contactor. If there is voltage at
the contactors, proceed to “Mercury contactor” for next
check. If there is no voltage at the mercury 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
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 contactor, replace the oven
control. If there is supply voltage output to the
contactor, proceed. S.S. Relays Check for supply voltage to the contactor coil. If voltage
is present and the contactor will not activate, replace
the contactor Also check each contactor for high
voltage input and output. Heating element(s) Check the Amp draw on each power leg for proper
load. Check the specification plate for rating
information. If the Amp draw is high or low, check the
