Harry J Irving , TX July 13, 2014 Appliance: Frigidaire Frg(V2) / 24 " Built - In Dishwasher FDB949GFS0 Frigidaire Dishwasher Fdb949gfs0: 18 year old dishwasher had used up 3 of the rollers that hold the 'upper rack roller assembly' in place. How to replace Dishwasher Dishrack Roller. I had just got home from having shoulder surgery - so I could not hold a screwdriver or reach inside the washer to remove or install the rollers. So I asked my daughter if she would do the installation. She watched the "appliance pro film' showing steps to be taken in removing old and installing the new rollers - she let me remove the washers from the old rollers. I didn't time her - but I estimate that the whole procedure was less than 30 minutes. Everything fit as it was supposed to and according to my daughter the film was very valuable to her.
