Removing control unit or display on Thermador RDF30...instructions say to remove the maintop; this is a pain and NOT necessary.

1. Remove the 4 screws under the top front panel and slide the front outer panel assembly (trim panels with end caps) down and toward the front to remove (there's a pressure spring (hold down clip) which makes this difficult);

2. Carefully rotate the glass panel up and away over the buttons, taking care not to break panel or buttons;

3. Remove screws from metal control mounting plate/panel;

4. This is the hard part: pull/rotate/cajole metal panel out from under the maintop. It's a tight fit between the burner valve stems and the maintop -- I used a nylon blade putty knife between the maintop and the panel to coax it out. After that it's easy: mark your connections and remove display.

TO MAKE THE REINSTALL EASIER (POSSIBLE) I used aviator snips to enlarge the holes for the burner stems in the metal control plate/panel (made them "taller"), and bent the top panel ("control cover") up a bit so it won't hang on the spark switch connections on the burner valves. Poor design IMO. But this method beats breaking your venturis by trying to take off the maintop.
