Customer Questions and Answers for Electric Range Electronic Oven Control Board by Frigidaire

Hello Lewis, Sounds like an infinite switch is starting to fail. If not, there could be an issue with the wiring harness. I would first remove the back and raise the top and check all of the places where the harness is tied together. There was an issue where the assembly line individual putting on the wire ties got too strong and was crimping wires together by tightening the wire ties too tight. Still a higher probability of an infinite switch going into failure but this is impossible to correct until the problem is every time. That is unless you replace all of the infinite switches.
