Kenmore Elite Electric Range 790.99012100
Right Front Burner heats only barely as it turns on and then off quickly.
This is a large burner element with outer and inner elements that are controlled with the same potentiometer.
I have checked continuity and short cut on both elements (inner = 45 ohms, outer = 35 ohms, not short cut detected).
Cables seem fine. As measured between ends of each element when the control is turned on, the voltage jumped to 245 volt and then goes back to about 12v instantly or few seconds later. It does stay rarely at 245 volts for even few seconds; I am not sure what makes the duration changes once in a while (range reset or hot surface switch activated does not seem to impact the behavior).
The hot surface switch seems to be working as well as the temperature limit switch (I did shortcut the temperature limit switch and it did not change the behavior).
I suspected the power board relays to be bad and even change one of the relay, but no success.
Any other specific test recommended to determine the power board need replacement?
Thanks.
