Our Frigidaire oven wouldn't reach operating temperature. First, I checked to make sure there were 240 volts at the terminal block. Next I found around 16.5 ohms resistance on both the upper and lower elements. Next I found 1,090 ohms on the sensor probe at room temperature, leaving just the Oven Control Board to be the culprit. Appliance Parts Pros got me the part the next day, and it took about 30 minutes start to finish to replace, including installation of the electrical surge filter that was included in the kit. I could have used the old overlay, as it was easily removed. But my wife insisted on a new one, and it does look better.
