So I opened the outside access door and the area looks clean. No signs of water, moisture or corrosion. The diagnostic LED is flashing once every 3 seconds which according to the service manual is a bad limit switch or air flow problems.
Where is the limit switch located?
Go to the following link and scroll down to post #6 by MikeandRuth. He describes the process of getting to the limit switch along with photos. His is an 8500-IV but hopefully it's similar to yours.
