The sad state of throw-away electronics really is a bummer. My Frigidaire Professional oven was giving me trouble. It would take an hour to pre-heat and even then it wouldn't get very hot. Long story short I determined it was the Oven Control Board. Seeing as how the oven is almost 18 years old Frigidaire doesn't make/stock that part. I was faced with buying a new $2K oven or trying to fix the OCB. We have an electronics repair place in town that has been in business since forever. Took the the OCB and they had it fixed and back to me in one day, it cost me $150 to have it repaired. The oven works like a champ again.
