I have a brand new (10 days old)JennAire induction cooktop model JIC4430XB. I broke the corner of the glass top. I am looking into replacing the glass. How complicated is it to replace the glass? is it as easy as removing the six torx screws holding the glass to the frame or is there something more involved? Is the user interface attached to the underside of the glass? Is there anything else stuck to the bottom of the glass on this model. I tried to get some info from a tech sheet on this model but it is not entirely clear. Is a service manual available? I have changed several cooktops in the past and I am comfortable with the basic appliance wiring and electrical safety issues. Thanks for the help.
