I have a legacy 1999 era Frigidaire Dual Fuel Stove/Oven (model FCS388WHCB) that I've kept alive thanks to good parts supply and a willingness to troubleshoot. I replaced the control board years ago due to a fading display, but that replacement board eventually failed as the electric oven did not come up to temperature. Now the original faded board shows a F3 fault code on cool down. The oven probe shows proper resistance at about 1100 ohms. Looks like I have two control boards with different failure modes! The control board is no longer available, but can be repaired. Replacing this range with a current 2022 era dual fuel stove is $2400 at a minimum. Single fuel (gas) would be considerably cheaper at ~ $950 but would involve rewiring a 220 to 110 circuit... My best option would be to get one of those control boards rebuilt. This is the disassembly procedure. Looking forward to an UPfix final solution!
