Woke up in the middle of the night with the stove beeping..... code F-11.... pushed cancel and it would just start up again.... the number 3 stopped working... would be hard to get cancel to work. Unplugged and plugged back in..... checked all connections in the back and all were tight. This happened all in the same day not over time!!!! Got online and researched Frigidaire FGEF3055MFF F-11 error code..... Ordered the OEC and the cheapest place was AppliancePartsPros.com!! Simple to install and better yet it fixed the problem!! Even called customer service just to confirm I was installing filter correctly and they were very helpful!! Thanks AppliancePartsPros.com you saved me lots of money!!! As far as my Frigidaire appliances I can't say too much good about them!
