Oven temperature getting hotter as the cooker gets older

If turning the temperature down using the oven control 

knob has not worked, or has only worked for a short 

time, then you may need a new thermostat. This should 

be fitted by a service person.

An oven light is not working

The bulb has probably burnt out. You can buy a 

replacement bulb (which is not covered under the 

warranty) from a good electrical shop. Ask for a 15 W – 

230 V lamp, FOR OVENS. It must be a special bulb, heat 

resistant to 300 °C 

(Fig.6-1)

.

Turn off the power at the circuit breaker.
Before removing the existing bulb, turn off the power 

supply and make sure that the oven is cool. Open the 

oven door and remove the oven shelves.
Unscrew the bulb cover by turning counter-clockwise. It 

may be very stiff 

(Fig.6-2)

.

Taking care to protect your fingers with a glove in case 

the bulb should shatter, unscrew the old bulb.
Screw in the new bulb; screw back the bulb cover. Turn 

on the circuit breaker and check that the bulb now 

lights.

The oven door is misaligned

The bottom hinge of either oven door can be adjusted 

to alter the angle of the door 

(Fig.6-3)

. Loosen the 

bottom hinge fixing screws and use the notch and a flat 

bladed screwdriver to move the position of the hinge to 

set the hinge position 

(Fig.6-4)

.

Retighten the hinge screws.
