power cord is unplugged then press and hold the
button for 30 seconds to reset the control board.
3. Plug the rotisserie back in and test the unit, if you
are still experiencing problems with the control
panel, proceed to section 1.2 on page 2.

Ensure the rotisserie is switched off, unplugged and cool to the touch before
performing this procedure.
Always verify the function of the control panel via the display screen, do not use sounds to
verify their functionality.

however the locations of components and the procedure will remain the same.
The best method for testing the functionality of all the buttons on the control panel can be
found in Section 1.4 at the end of this document.
