Turbofan Convection Oven
Element faulty / blown
NOTE: In bake mode (50—270°C or 100—550°F)
the outer coil only of the top element assembly
operates. The inner coil works only when in grill
or broil mode.
With thermostat on and heating check voltage
across top element terminals at rear of oven. If
voltage is correct then check current draw of the
element. If there is no current draw then the
element is faulty—replace.
If there is no voltage check voltage is being sup-
plied to the top element from terminal two on the
switch block mounted to front of thermostat.
If voltage is correct then check wiring.
NOTE:
Top outer element current draw:
208V :
3.8A ± 5%
220—240V: 3.5A ± 5%
6.1.13 TOP ELEMENT NOT WORKING (IN
BAKE MODE—NOT GRILL / BROIL)
Indicator faulty
Check the voltage across the indicator terminals.
If the voltage is correct then the indicator is
faulty—replace.
If there is no voltage then check wiring.
6.1.14 NO THERMOSTAT HEATING
INDICATOR
Element faulty / blown
With thermostat in grill or broil position (fully
clockwise), check that the grill indicator on the
control panel indicates. If not, then check the
voltage at terminal P5 on the thermostat switch
(fig 6.4.1). If there is no voltage check that the
switch has power on terminal 5. If there is power
at terminal 5, but not at P5 when thermostat is in
grill position, then the switch is faulty—replace
thermostat assembly.
6.1.15 GRILL NOT WORKING
Indicator faulty
Check the voltage across the indicator terminals.
If the voltage is correct then indicator is faulty—
replace.
If there is no voltage then check wiring.
6.1.16 GRILL INDICATOR NOT WORKING
No power to timer
Check the voltage at terminal 5 on underside of
the 180 minute timer.
Check that one lead of timer motor is connected
to terminal 5 of timer and the other lead is
connected to neutral of ‘Roast ’n Hold’ switch.
If voltage at terminal 5 is correct and wiring is
correct then the timer motor is faulty—replace
timer.
If there is no power at terminal 5 check for power
supply at terminal 4 of timer. If there is voltage at
terminal 4 and not at terminal 6 with timer set,
then timer switch is faulty—replace timer.
6.1.17 ROAST TIMER (180 MINUTE) WILL NOT
TIME DOWN
If there is no voltage then check voltage is
being supplied to bottom element from terminal 6
on switch block mounted to the front of the
thermostat (fig 6.4.1). If no voltage at 6 then
check for voltage at terminal P6. If power to P6
(and none to 6), then the thermostat is faulty—
replace.
NOTE:
Correct bottom element current draw:
208 V :
9.6A ± 5%
220—240V: 8.7A ± 5%
From Serial Number 232054:
If no voltage at terminal 4, check the relay
behind the control panel is energised (i.e.
voltage across terminals A and B). If there is
no voltage then check wiring from the hold
switch. If there is voltage then check that
there is voltage at terminal 4 and terminal 7 of
Figure 6.1.7
Terminal 4
Terminal 1
Terminal 2
Terminal 5
Terminal 3
Terminal 6
If grill indicator is illuminated, but the top inner grill
element is not functioning, check the voltage at
the top inner element coils at rear of oven. If the
voltage is correct then check current draw of
element. If there is no current draw then element
is faulty—replace.
NOTE:
Top inner element current draw:
208 V:
8.7A ± 5%
220—240 V: 7.8A ± 5%
