Greg C Cincinnati , OH March 20, 2015 Appliance: Frigidaire Electric Range PLES389DCC Frigidaire Range Ples389dcc: We had an f1 error on our frigadare stove. How to replace Clock Timer. Ordered a new clock/timer control. This was very easy to install the real trick was removing about 8 wires and 4 plug in connectors from the board and then reinstalling them back in the same location as the were before. I took a photo of the board with my IPhone before taking all the wires off, this made it very easy to reinstall the wires on the same terminals as before. There are 2 additional connectors on the board that a flat ribbon cable from the touch button panel attaches to. Do not just pull the ribbon cable out of these connectors. On the ends of the connectors there are very small tabs that slide up to release the ribbon cable. They may be hard for some to see, but they are there, simply slide the tab up on both sides and the ribbon will release. When reinstalling the ribbon cable, make sure it is pushed all the way down in the connector before pushing the tabs down to lock it in place. The total time to do this job is about 10 to 15 minutes and the F1 error is long gone! 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
