The Moducontrol starts the outdoor fans a few seconds after the compressor starts and allows the fans to run to the end of the cooling or heating caller. The compressor stops and the fans continue to run for a few seconds afterword. Check the wiring connections at the MTA, Moducontrol ( M1S-1, M1-1), fan run capacitor and motor lead connections. Check fan, run capacitor with capacitor tester All fans are 230 volt single phase. Check the fan windings for short, open, or grounded conditions.
