Betty K Cherokee , IA August 06, 2014 Appliance: Frigidaire Freezer LFFU14F5HWF Frigidaire Freezer Lffu14f5hwf: The freezer would stop running the touchpad didn't work and it showed non numbers in that area the only thing that would start it again was to unplug and plug it back in. How to replace User Control Board. After reading the trouble that other people had that were similar, I ordered the part and when it arrived my freezer is back to normal!! Thank you very much! 32 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
