I have a Pelpro PPC90 / TSC90 pellet stove. It will start up, blower come on, show bios version 0.00, then throw an error code for the control board not communicating with the control panel. I tested the ethernet cable between the two and every conductor has continuity, so that's not the issue. Is this the infamous control board failure? Is a new board the only option, or can this one be re-flashed if it has lost its firmware, or are there any other known components on the board that could be causing this?

Thanks!
