Rheem P-M337A Front Panel Removal

[SeaBear]

I need to replace the power switch on this Rheem P-M337A header, since the switch has seized up. Wondering if anyone can advise me on how to get the front cover off. Online manuals suggest I should first remove a knurled knob in the center (which isn't present). Guessing I just pull the entire panel out, or up - but it seems very tight and i'm not wanting to damage anything. I can see that when I have the panel off, it should just be four screws to let me drop the display panel, but obviously can't do that until I can figure out how to get the main front panel off.

If anyone can point me in the right direction, would be most grateful!

@1poolman1 may have ideas.

This portion is the removable face. Pull the top right and left portion of the face horizontally toward the photographer. Check that there are no screws on the sides or top of the U face. No knurled knob on earlier versions.

Thanks @PoolStored. I figured it would be something like this. I'll give it a shot in a couple of days when the new switch arrives, the rest should hopefully be straightforward (famous last words).
Your assistance is much appreciated!

Once again @PoolStored, thanks for your guidance. The cover is off. There were two screws (well hidden) in the recess of the faceplate that had to be removed first. Adding an updated picture showing the location for anyone who needs this information in the future. Approximate screw locations are highlighted.
