Check the Compressor connections and wire harness.
If no defect is found replace the Duct assembly as shown.
Note: In our practical experience, a tech that encountered this error code, found the system was empty of refrigerant. As with any other issue with the sealed system on these units the entire system needs to be replaced.

Advance the test mode to step 17. Watch the fan RPM, (should be approximately 4000). And the Compressor RPM should be approximately 50. If the compressor will not reach this RPM then replace the assembly.
Note: If any part of the sealed system or sensors or blower located on the Duct Assembly is defective, you must replace the whole Duct Assembly.
