Hi all I have a 2005 englander 25-EPI and the lower 3 settings LFF, LBA and AOT will not allow me to change any of them for some reason? I recently swapped boards with the original one as my brother in law had got another stove and took the board from mine due to wiring and solder issues, long story short the PDVC board would allow me to change all the settings, When I installed MY board back into my unit I no longer have the capability to adjust the Low fuel feed. Any help would be great! Thanks all
