Red light on on PCB...manual says indicates replace pcb (there is only one light on the pcb). If so, I need another pcb sent to me. My issue with machine was/is not drying clothes...gets hot, new blower works but clothes stays wet - cleaned out condensing duct, replaced blower, new dry duct thermistor, but checked pcb and saw red light - again. So shouldn't I replace pcb and run diagnostics? Can I run diagnostics with a red lit pcb?
