This is normal operation for current coil heating elements and is not an indication of problems with the coils. As of June 1, 2018, changes have been made to the standards for all electric coil elements. Ranges and cook-tops using this type of burner are now equipped with temperature-limiting coils to further reduce the risk of unattended cooking fires. The elements should not be replaced unless it is confirmed they are malfunctioning for other reasons. See the training pointer attachment for complete details. I do not think you need a control board or element.

See the technician sheet and wiring diagram. Yes, there is a delay on the variable speed compressor starting along with the condenser fan motor. Once they are running, do they stay on ? I am assuming the evaporator fan motor is running . If all fan motors and compressor is running , I would look at the frost pattern on the evaporator for a possible sealed system issue.

Hello, the next step would be to check the ( magnetic Reed switch ) . The complete step by step diagnostics are on page #86 in the manual link in this post.
