Hello all I thank you for your advanced help. My brother in law gave me an older unit. It is an englander model # 25-pvd/55-shp22. The serial number is whi-012803 and the manufacturing date says 07101? I received this thing not working properly. I went to pick it up and could see obviously it was improperly cared for. He had a reducer on the vent pipe that went from the 3" pipe to a 7" pipe. When we pulled the flue off there was literally 50 pounds of ash inside the flue. Horrible care. He said he cleaned it once a year cause it was so big. I didn't say anything but I knew that wasn't right. Anyways the reason he gave it to me is when you plugged it in and turned it on the heat setting has a dim colored 9 lit and a bright looking 1 on the heat side and the blower setting was stuck on 9. It would read that for about 30 seconds and then both setting would go to dashes. The buttons don't do anything. It's like frozen. Also when you 1st Turn it on the low fuel feed light is lit and the air on temp is lit. After the 30 seconds everything turns off except the power on light and the dashes on the screen. The board is the pucb98. My 1st thought was to replace the board, but I seen someone talking about resetting the board. I can't find any information on resetting the 98. I see resetting the pucb04 but not the 98. I would like to try that before I replace it. I may also change out some resistors 1st. A few aren't reading correctly. Please help me
