6.1.8 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 6.1.7).
6.1.9 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.
Timer not switching on buzzer
With timer in zero position, check voltage to
top connection (terminal one) and bottom
connection (terminal two) of timer. If there is
no voltage at terminal one then check wiring.
If no voltage at terminal two then timer is
faulty—replace.
NOTE:
Timer will continue to run
approximately three minutes below zero.
Buzzer and time up indicator will continue until
the timer is manually switched off (to vertical
position).
6.1.10 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.
6.1.11 NO TEMPERATURE CONTROL
(TEMPERATURE OVERRUN)
Thermostat faulty
With thermostat in off (vertical) position, the
heating indicator should be off. If not then the
thermostat is faulty—replace.
6.1.12 SLOW RECOVERY
Thermostat out of calibration
Place an accurate digital thermometer probe
in centre of oven. Set thermostat to 180°C or
355°F. Close the oven door and allow oven
thermostat to cycle on and off twice. Record
oven centre temperature for the next
thermostat on and off cycle. The thermostat
should cycle on and off between 165°C and
195°C or 330°F and 385°F when set to the
above temperature. If oven temperature is
outside these ranges, then the thermostat
requires recalibration.
NOTE:
Thermostat cycling span should be
±15°C or 27°F
Indicator faulty
Check the voltage across the indicator termi-
nals. If the voltage is correct then the indica-
tor is faulty—replace.
If there is no voltage then check wiring.
6.1.13 NO THERMOSTAT HEATING
INDICATOR
Buzzer
Buzzer Terminals
Figure 6.1.4
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 wir-
ing 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:
208 - 240V
3650 ohms
110V
1085
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.
