I checked each element terminal to the casing and there is no short. I checked the heater relay between N.O.Black and COM Red and that circuit is open.(The N.O.Black connector shows signs of overheating.) I checked the inlet thermistor at P4 pin 1 and P4 pin 2 and found 48800 ohms. I also found a Service Tech Sheet when I opened the Machine Control Electronics. Under "Heat will not shut off" troubleshooting, it refers to P4 pin 3 and P4 pin 6 at the connector.(disconnected.) My reading is 9k to 10k ohms. It suggest that I replace the machine control electronics with a reading between 5k and 15k ohms. Do You agree?

ANSWER Ron, Yes, I agree, all your heater circuit components check OK, Problem would have to be in the control board circuit or components. Good Luck.
