6.1.4 FAN DOESN’T OPERATE
Fan motor faulty
Check the supply voltage across motor termi-
nals. If there is no voltage then check the
electrical connections of wiring.
If voltage is correct then check the oven fan
for free rotation. Remove any obstruction.
If fan is free to spin and the voltage at motor
terminals is correct, then the motor is faulty—
replace.
Fan switch faulty
Check that the thermostat has power to
terminal 5 on switch body on the front of the
thermostat when power switch is ON. If no
voltage check wiring, check that terminal P5
has power switched to it when the thermostat
is turned on. If no power to P5 then switch is
faulty and thermostat complete with switch
needs to be replaced.
6.1.5 OVEN LIGHTS NOT ILLUMINATING—
DOOR OPEN (AUTOMATICALLY ON)
No power to lights
Check the supply voltage across lamp hous-
ing terminals at RH side rear of oven. If the
voltage is correct, replace the bulb (if faulty).
If the bulb is OK, check lamp housing.
Replace if faulty.
6.1.6 OVEN LIGHTS NOT ILLUMINATING—
DOOR CLOSED (MANUALLY SWITCHED
ON)
Light switch faulty
Check voltage to the bottom terminal of the
switch. If there is no voltage, then check
wiring.
With switch depressed, check voltage at top
terminal. If there is no voltage, then replace
the switch.
If voltage is correct, then check wiring to light.
NOTE:
Alternately, perform a continuity test
across the terminals with the light
switch depressed.
6.1.7 NO WATER INJECTION / STEAM
Steam switch faulty
Check voltage to the bottom terminal of the
switch. If there is no voltage, then check
wiring.
With switch depressed, check voltage at top
terminal. If there is no voltage, then replace
the switch.
If voltage is correct, then check wiring to the
solenoid.
NOTE:
Alternately, perform a continuity test
across the terminals with the steam switch
depressed.
Fault with water valve
Check voltage supply across the water valve
Thermostat faulty
Set thermostat to 200°C or 400°F. Check the
voltage out of terminal 1 on the thermostat. If
there is no voltage then the thermostat is
faulty—replace.
If the voltage is correct and the heating light is
on then check all wiring to heating contactor.

Burner faulty
With burner removed (refer 6.3.22), inspect
burner for leak holes in construction and
deterioration in mesh surfaces. Tears or
corrosion holes in mesh will be evidence of
faulty burner condition. Replace burner if
faulty.
NOTE:
Minor mesh surface buckling is
normal, and will not necessitate burner
replacement.
6.1.3 BURNER NOISY
these terminals when ‘Roast ‘n Hold’ is not
selected.
If there is no voltage, open oven door and
manually depress door microswitch actuator
at bottom right of oven. If this activates the
lights, then the microswitch actuator arm
behind the control panel requires adjustment.
Check voltage across micro-switch terminals
to neutral.
With the door open there should be power to
the com terminal and the n.c. terminal.
If not, microswitch is faulty—replace.
