WARNING
To avoid risk of electrical shock, personal injury or death; disconnect power to oven and discharge capacitor
before servicing, unless testing requires power.

Convection Temperature Test
NOTE:
It is absolutely necessary to own and use a
thermocouple type oven tester to accurately
measure oven temperature. No other type of
thermometer can take its place.
NOTE:
Before testing an oven to check calibration,
inspect the RTD for proper mounting.
1. Place one wire rack in center position. Remove
any other racks and utensils.
2. Clip thermocouple to the center rack and run lead
outside oven door, or wrap thermocouple around
rack and have the tip of thermocouple extend
upward towards top of cavity approximately 1
inch.
3. Press
PREHEAT ON/OFF
pad.
4. Press
PROGRAM SAVE
pad.
5. Press
TEMP
pad.
6. Enter 230° C (450° F).
7. Allow oven to cycle one time.
8. Record high and low peaks from next two cycles.
NOTE:
Display
does not
indicate if heating elements
are on or off.
Fahrenheit Example:
LOW
HIGH
Cycle 1
440° F
460° F
Cycle 2
439° F
461° F
879° F +
921° F = 1800° F
1800° F / 4 = 450° F average temperature
Celsius Example:
LOW
HIGH
Cycle 1
230° C
240° C
Cycle 2
230° C
240° C
460° C +
480° C = 940° C
940° C / 4 = 230° C average temperature
If the average temperature is too high or too low the
oven temperature offset needs to be calibrated.
Convection Temperature Calibration
NOTE:
It is normal for the average oven temperature
to vary from the oven setting by as much as
14° C (25° F). Difference will not effect
cooking since recipes are written with this
difference in mind.
Calibration
NOTE:
Door must be closed and unit must be in
STANDBY mode.
1. Press
HIDDEN PAD
.
2. Press pads
1,3,5,7, 9
.
3. Press
"0"
pad.
NOTE:
Display will show the current offset setting.
4. Press the
"0"
pad to change the offset.
Fahrenheit
NOTE:
Offset temperature range is +40° F to -40° F
and advances in 2° and 3° increments.
Celsius
NOTE:
Offset temperature range is +22° C to -22° C
and advances in 1° and 2° increments.
5. Press
STOP/RESET
pad to save offset changes.
NOTE:
Retest the oven after any offset changes are
made.
Fahrenheit Example:
• Oven temperature is set for 450° F.
• Average of temperature test is 475° F.
• Offset setting must be reduced by 25° F.
• If offset is shown as 10°F, press the
"0"
pad.
until -15 is shown in the display (10 – 25 = –15).
Celsius Example:
• Oven temperature is set for 230° C.
• Average of temperature test is 240° C.
• Offset setting must be reduced by 10° C.
• If offset is shown as 5°C, press the
"0"
pad
until -5 is shown in the display (5 – 10 = –5).
