Frigidaire oven temp off. Tried calibration...unable model BGGF3042KFT

[AWSHandy]

This oven is 25 degrees lower than set temp.  I tried to calibrate (hold "bake" for 8 seconds then adjust) but control would not do this.  After holding bake for 8 seconds it only goes back to the clock.  I tried many times.  Sounds like a control board issue.  Should I replace temp sensor and control board?

Try calibrate first, then check oven probe or replace, last be module replacement. 

Calibrate directions:

1. Set EOC to bake at 550°F.

2. Within 5 seconds of setting 550°F, press and hold the bake pad for approximately 15 seconds until a single beep is heard (longer may cause F11 shorted keypad alarm).

3. Calibration offset should appear in the display.

4. Use the slew keys to adjust the oven temperature up or down 35°F in 5°F increments.

5. Once the desired (-35° to 35°) offset has been applied, press Press Stop/ Clear or Cancel. Note: Changing calibration affects normal Bake mode.
