Hi everyone. I picked up a used Accentra 2 and there's no control panel on it. There is a screwed door on the back that doesn't seem to want to open on the back but there's just the circuit board in there. Should I have gotten a remote control board with it? I'm finding Harman dealers in my area to be pretty useless. The stove was made in 2006 if it matters. Thanks in advance.
