Bought a used 25PDV stove made in 07. getting an E2 code about 10 seconds after pushing the on button. I've reset the mode to d, adjusted the codes to 6-4-1, reset the control board, jumped out both pressure switches, replaced the combustion blower, done diagnostics, can't seem to get anywhere. I've read other threads for about a week and learned alot, but want this thing running. the convection blower starts up when it E2's. Any help would be greatly appreciated
