BURNER REPLACEMENT
To replace either main burner or the pilot cross tube burner follow steps listed under
GAS
CONVERSION
until the point is reached when the burner can be replaced.
Always ensure burners are correctly fitted over injectors.
ELECTRICAL
Always ensure oven is disconnected from mains supply
MOTOR AND FAN ASSEMBLY REPLACEMENT
Ensure the oven is disconnected from the mains.
Unscrew the four knurled head screws and remove the fan baffle. Remove the eight
screws retaining the fan and motor mounting plate situated on the oven back. The fan
and motor assembly can now be pulled into the oven sufficiently to disconnect the wiring.
The fan motor unit can then be removed from the oven.
To remove the fan, slacken the two socket head grub screws spaced at 90
o
on the fan
boss. The fan can now be removed. If trouble is experienced, use of a fan puller is
recommended. Reassembly is the reversal of the above procedure. No lubrication of
either the fan or motor is required as they are both self-lubricating.
OVEN LIGHT REPLACEMENT
Unscrew the four knurled head screws and remove the fan baffle. To replace a blown
bulb, unscrew the glass covers anti-clockwise. The bulb is a 40 watt Minature Edison
Screw bulb. Screw on lamp glass cover clockwise. Access to the light wiring is by
removing the back panel. To access the light switch, remove the screw holding the
control panel closed and open the control panel.
IGNITION CONTROL BOX REPLACEMENT
Ensure power is off to the oven. Remove the side service panel from the RH side panel.
The ignition pack and wiring will now be exposed. Replace the faulty components as
required, ensuring correct rewiring to the schematic at the back page. When servicing is
completed, replace the service panel securely.
IGNITION ELECTRODES
If ignition of the gas burners is unreliable or delayed, it could be because there is a fault
with the ignition electrodes found next to the R/H main burner under the oven base. To
observe correct operation of the ignition system firstly remove the oven internals,
including the ceramic tiles, as described under
GAS CONVERSION
. Remove R/H
exterior panel. Turn on the electrical supply. (Gas supply off). Turn on the oven
thermostat. A sparking cycle should be observed at the end of the spark (kinked) and
earth (centre) electrodes.
If not, check electrode gapping and adjust if necessary.
Between SPARK (kinked) and EARTH (centre) 3-5mm
Between EARTH and main burner 7-10mm
Between SENSOR and EARTH 10-12mm
Between SENSOR and main burner 7-10mm
If gapping is correct but there is no spark at electrodes then the H.T. electrical circuit
should be checked for shorts, providing the ignition control box is functioning correctly. If
there are any shorts in the electrode assy, i.e. in the electrode insulators or terminal block
then it is suggested that the assy be replaced rather than repaired to guarantee faultless
repair.
