Blower not operating upon arrival. At air handler control board coded “blower motor communication error”. High and low voltage both good at control board. Tried reset board couple time but would immediately code again. All signs indicating blower motor has failed. I replaced blower motor, board still giving same fault code. We then had to replace board. After installing new board, got code for “no data network “. Which means board had to be reprogrammed for unit using memory chip. I had to go to Goodman purchase memory chip and return to home again. I programmed board. System now operating. Monitored system operation for a while to ensure air handler or condenser did not go in to lockout mode again. System operating at time of departure.
