Replacement Parts Sought for 5 yr old PA-II Classic

Our venerable PA-II unit has died in our coastal zone, but I’d like to try to give it a second life, if possible.

Symptoms:

  • Red LED on; 3.3 v present on control board; board looks clean
  • no WiFi present
  • one fan spinning - other spins 0.5 rotation, then stops
  • no serial port connection when using Utility … I added the drivers … PC not detecting the PA-II port

The MAC address is : 40:F5:20:16:F5:BA + Order: PA17601

Would you concur with a likely board & sensor failure?
If parts available, can you please advise on pricing. Thanks!
