UNIT WON'T SPIN OR AGITATE

THE LED ON THE INVERTER IS BLINKING, IN A SEQUENCE, WHICH INDICATES NORMAL OPERATION. THE UNIT WON’T AGITATE OR SPIN IN THE TEST MODE EITHER. WE HAVE CHANGED THE LID SWITH, MOTOR AND THE MAIN BOARD WITH NO CHANGE. THERE ARE NO ERROR CODES LISTED IN THE TEST MODE. I’M THINKING THAT, ALTHOUGH THE INVERTER IS INDICATING NORMAL OPERATION, THE INVERTER IS THE ROOT. I ALSO SWAPPED THAT OUT WITH NO CHANGE. WE BUY THE APPLIANCES WHOLESALE AND REFURBISH THEM SO I’M DEALING WITH NEW PARTS. ANY IDEAS OR SUGGESTIONS WOULD BE APPRECIATED.
