SUB–123P SERVICE AND REPAIR MANUAL
1) Place a thermocouple or a reliable thermometer on a pan in the center of each cavity.
2) Turn on the oven and proofer cavities of the unit by pressing the buttons labeled power
3) Allow the temperature in the oven and proofer to stabilize.
Important Note: Allow the oven to cycle at least twice before attempting to
4) Note the maximum temperature readings of the thermocouple or thermometer and the
corresponding temperature display.
5) Subtract the maximum temperature of the display from the maximum value of the thermocouple
or thermometer. For example; the maximum temperature on the display was 356 and the
maximum temperature of the thermocouple or thermometer was 351. (351 - 356= -5) The offset
for the oven would be negative five.
6) Press and hold the enter key for approximately 15 seconds until a beep is heard.
7) The offset screen will now be displayed. The recipe buttons (labeled button 1 – button 6 in the
above drawing). Button 1 will decrease the humidity offset by one, button 4 will increase the
humidity offset by one. Button 2 will decrease the proofer temperature offset by one, button 5
will increase the proofer temperature offset by one. Button 3 will decrease the oven temperature
offset by one, button 6 will increase the oven temperature offset by one. Using the above
example; press button 3 five times.
8) After entering the desired offsets press the enter key to exit the offset screen.
9) Allow the temperature to cycle again and observe the maximum temperature as describe in
step 4. If the temperatures are the same the unit is properly calibrated and ready for use. If the
temperatures are not the same, repeat the calibration process beginning with step 4.
