6.1.3 OVEN LIGHTS NOT ILLUMINATING -
DOOR OPEN (AUTOMATICALLY ON)
No power to lights
Check the supply voltage across lamp
housing 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.
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.
6.1.4 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.
6.1.5 NO WATER INJECTION / STEAM
Fault with water valve
Check voltage supply across the water valve
solenoid coil with the steam switch depressed.
If there is no power supply then check the
control panel steam switch.
Check voltage to the bottom terminal of the
switch. If there is no voltage, then check
wiring.
With switch depressed, check for voltage at
top terminal. If there is no voltage then
replace switch. If voltage correct, check
wiring to solenoid coil.
If power supply to the coil is correct,
disconnect wiring to coil and check the
resistance of the coil windings.
Correct coil resistance: 3650 ohms
NOTE:
If open circuit / high resistance, then
the coil is faulty—replace.
If coil resistance is correct, rewire and listen
for an audible solenoid click when the steam
switch is depressed.
If solenoid can be heard functioning, and oven
water nozzle is not blocked, then remove
water solenoid and fittings and check for
blockages.
6.1.6 CONTINUOUS WATER OUT OF
OVEN WATER NOZZLE
Water solenoid electrical fault
With control panel steam switch not
depressed, check for power supply across
solenoid coil. If there is power to the coil, then
check wiring and steam switch (refer 6.1.5).
6.1.7 60 MINUTE TIMER NO TIME UP
BUZZER
Buzzer faulty
With timer in ‘zero’ position, check the buzzer
at side 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.
