Scott B Grand Rapids , MI November 24, 2015 Appliance: Frigidaire Range PLEFMZ99ECA Frigidaire Range Plefmz99eca: F5 00 error on frigidaire pro series range. How to replace Clock Timer. Nothing on the display was working, only the F5 00 error code when I tried to turn on any of the burners. After much research at this site and other random sites, I determined I needed to replace the EOC. It was a very simple job. I was able to re-use the button display from the old EOC after carefully peeling it off. The shipping was as advertised! Ordered it late Thursday night, had it on my doorstep on Saturday morning, and that was using "ground" shipping. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
