two screws on control panel holding
thermostat.
5) Carefully remove two screws holding fan
switch to thermostat.
HINT: Tape fan switch assembly together
before removal to prevent it from spring-
ing apart.
6) Adjust the calibration nut located at the
base of the thermostat shaft.
To increase oven temperature, turn
calibration nut anticlockwise.
To decrease oven temperature, turn
calibration nut clockwise.
Adjustment of the calibration nut by 1°
angular will alter oven temperature by
approximately 2°C (3.6°F).

CALIBRATION - UK UNITS ONLY
1) Place a digital thermometer inside the
oven.
2) Set the thermostat to maximum setting.
3) When thermostat cycles off check oven
temperature against dial setting. If
overtemp has tripped (as indicated by
power loss to unit) before oven has
reached set temperature then the
overtemp is out of calibration - replace,
refer section 6.3.16.
4) If overtemp trips but oven temperature
has exceeded 330°C, then the thermostat
is out of calibration - re-calibrate - refer
section 6.4.2.
7) Reassemble fan switch onto thermostat
and fit assembly back onto control panel.
8) Turn on power and then recheck oven
thermostat calibration.
9) Repeat procedure if necessary.
NOTE: Thermostat cycling span should be
±15°C or 27°F.
