I have a Englander PAH 25 and am having dirty burn issues. I have torn the stove apart as well as venting system and cleaned it well. I have checked all gaskets and they are in great shape. I checked the burn settings of the control board and they are set at 1-1-1 which I know are incorrect. I believe the default setting should be 1-4-1. I have tried changing them but they wont change. I have tried rebooting by unpluging and pluging back in and holding all 3 lower buttons. It says 1-1-1 as still wont change and of course its saturday and no tech support. BTW the stove is about 2 months old. Please help.
