Goodman GMPN080 Rapidly Flashing Light on Control Panel

Goodman gmpn080-4 Rev. B has a rapid flash on the control board. The compressor turns on and runs but the GMPN runs then shuts off, runs then shuts off continuously. The flash code problem names these as issues (INCORRECT TWINNING INCORRECT PRIMARY POLARITY) and to check these (REVERSE TRANSFORMER STICKING GAS VALVE SECONDARY LEADS REVERSE PRIMARY WIRES) . The drain pan was holding a little water and the whole area was damp. I shut the unit off over night and I removed the water and tried it a little while ago and the same quick flashing light on the panel. Any suggestions. Thanks.
