This customer had used the oven for about four hours earlier in the day. The oven was off and the bake element shorted out. I know there is always 110v volts to one side of the element. Is it common for an element to short out on it’s own when not in use? Customer is worried that there may be something wrong with the control board. I replaced the bake element and checked for power from the board. The only power present is on the one side coming from the terminal block. Control turns the element on and off with no problems. Control board has no visible problems and is working fine. Is there any concern here? Thank you in advance.
Since the oven control was OFF, this means the L1 through the bake relay was not affected. This my not be the case had the circuit been controlled by the ERC when the event occurred. The fact that the element shorted after it began to cool down means that only the reconnected L2 circuit was involved. This could not have affected the control relay. An element can fail at any time. The light show of the element shorting out would have been much more extreme if it failed with 240 across it.
I would not have concern for the control since it was the L2 side that shorted. The element wire inside probably just warped and touched the outer shield as it was cooling off and contracting back into place.
