How to replace Electronic Pc Board. Unplug unit first be careful there are sharp edges. not a bad repair had to pull unit half way out of window to access the board. took longer to get to the part because of all the screws but they are all the same size witch makes it easy to put it back together. just have to plug a bunch of wires in took them off one at a time so as not to mix them up some had glue around them i used a small soldering iron to carefully remove it and they came off easy. took about an hour but well worth the time and a lot cheaper than buying a new unit. great part fits perfect works better than original. 7 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
