Revision 1/F3563
Fan motor faulty
At rear of oven, check that there is supply
voltage from neutral to both of the phase
terminals on the motor terminal block.
6.1.3 OVEN LIGHT NOT ILLUMINATING—
DOOR OPEN
No power to light
Check the supply voltage across lamp
housing terminals at rear of oven. If the
voltage is correct, replace the bulb (if faulty).
If the bulb is OK, check lamp housing.
Replace if faulty.
If there is no voltage, check voltage across
micro-switch terminals to neutral.
With the door closed there should be power to
the com terminal and the n.o. terminal.
With the door open there should be power to
the com terminal and the n.c. terminal.
If not, microswitch is faulty—replace.
Light switch faulty
Check voltage to the top terminal of the
switch. If there is no voltage, then check
wiring.
With switch depressed, check voltage at
Timer not switching on buzzer
With timer in zero position, check voltage to
terminal 1 and terminal 2 of timer. If there is
no voltage at terminal 1 then check wiring.
If no voltage at terminal 2 then timer is
faulty—replace.
NOTE:
Buzzer and time up indicator will con-
tinue until the timer manually switched off (to
vertical position).
6.1.7 NO HEAT
No power to thermostat
With door closed, check voltage to terminal P
of the oven thermostat. If there is no voltage
then check voltage to terminal NO of door
microswitch. If there is no voltage then refer
6.1.2, microswitch out of adjustment / faulty.
If there is voltage then check wiring to the
thermostat.
6.1.6 60 MINUTE TIMER NO TIME UP
INDICATOR
Indicator faulty
With the timer in the zero position, check for
voltage across the indicator light. If correct,
then the indicator light is faulty—replace.
If there is no voltage then check wiring.
6.1.5 60 MINUTE TIMER NO TIME UP
BUZZER
Buzzer faulty
With timer in ‘zero’ position, check the buzzer
at bottom of control panel (inside) for voltage
across terminals. If voltage is correct then
buzzer is faulty—replace.
If there is no voltage, then check wiring.

The resistance should start low and quickly
increase to infinity within 5-10 seconds. If the
resistance does not increase at all, then the
capacitor is shorted - replace. If the capacitor
is infinite resistance straight away then it is
open-circuit - replace. If the resistance never
goes very high then the capacitor is leaky -
replace.
6.1.4 OVEN LIGHT NOT ILLUMINATING—
DOOR CLOSED
If the voltage to the motor terminal block is
correct, and the capacitor is not faulty, then
check the oven fan for free rotation. Remove
any obstruction.
If fan is free to spin and the voltage supply is
correct, then the motor is faulty—replace.
bottom 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.
