Hello, I have a 25PDVC built in 6/06. Top auger stopped feeding. runs fine in diagnostics mode. jumpered out both sensors Replaced temp sensor, same issue, replaced IC chip, no avail. in diagnostics mode i get an 8 for temp in any mode, with the temp sensor plugged in or not. is it my board? or is it me? or is it something simple? thank you for you time, Edwin R.
