This error is pretty rare, but it can potentially be fixed quickly by double checking the screws on the "Compressor Control Module" or "Controller" (same part) shown below. There are five screws, they're typically 8mm. To check the Contoller, you'll need to disconnect power and remove the top shell from the unit. Do this by removing any straps, and wiggling one side at a time, starting from the middle, horizontal seam in the foam shell. After checking the screws, replace the control module, and verify the fans are seated fully/spin freely. Replace the top lid and wait 20 minutes before reconnecting power and testing the unit again. Contact support if the issue persists.
