Washer heater not working

New control board, new inverter, drain filter clean and drain pump works.
On Test Mode t07 heater does not produce heat. The thermistor has the proper 12 ohms @ 75 degrees. The heater element has the proper 15 ohms resistance. During t07 test the board is sending and the element contacts are receiving 119 to 148 volts and both element wires are reading 9.7 to 10 amps in the clamp meeter. Still the heater element does not heat up. Took element out and examined it. It looks fine. Put it in a pot of water and it still reads 15 ohms and no short to ground. Also tested thermistor again - proper ohms at 75 degrees and they go down as temperature of test water goes up.
If during the test mode the heater is receiving voltage and drawing amperage it has got to be heating but it is not the only thing that can be the problem is the heater itself. If the heater is actually putting out heat but the control fails to indicate that the water temperature is rising then the problem is the control (I know it is new), the thermistor or the wiring in-between.
Since you just replaced the control we will assume for now that it is ok. Check the wiring between the thermistor and the control board and if it is ok replace the thermistor even though it has the correct ohm reading.
Since the heater is has the correct ohm reading, it is not grounded out, it is receiving voltage and drawing current I am almost certain it is heating, so I believe the problem will be the thermistor or the wiring but I cannot be sure. GE Front Load Washer Test Modes
