If my brain is working properly.I think the slow spin speed prior to the Rapidry is 640 RPMs.I think the Rapidry is 880.Don't quote me on that.The timer selects the spin speed on the Permanent Press cycle only so the user doesnt make there Permanent press get permanently wrinkled.I had these in coppertone when I lived in Fells point where Devine from John Waters campy movies would come over and use them as we'd returned from our trip down the alyways in Baltimore's Highlandtown on the southeast side of the city, got high and talked true trash.I got mine from an add for a used washer dryer from "Refrigidaire" for $75.I replaced the original washer lid with a glass one and had to use a wire brush to scrape off all the carbin residue that had built up on the gas burner glow bar.Those were the hay days of FRIGIDAIRE and as we all know and miss tremendously,the 70's were the very last decade of FRIGIDAIRE Appliances as we knew and loved them.I must have sold hundreds of them and know they were made to last.They were not only extreamly effective in getting out ground in dirt but,they were the hugest capacity of any other washer and dryer. The capacity and the FRIGIDAIRE Rapidry spin made them gain the number two spot in Consumer REPORTS the following year second only to Maytag.However,Their dryers and electric range(Model RSE36S) were rated number one.In 1973,the Touch N Cook range was introduced and a new line of their Super Surge dishwashers with a new polipropeline tub were also unvailed.They also released the "GMini" compact washer and dryer.Similar to a "Skini-Mini" stacked compact washer and dryer but seperate instead of together.Amana made FRIGIDAIRE's microwave ovens(the open down door and three button controls gave that away imediately)and Poppy red was also unvailed but was only available on select models but became very popular.Moere so than avacado or coppertone.I feel like I'm venting but nobody has made anything near what FRIGIDAIRE (a division of General Motors)had designed,pionered,developed and tested non stop prior to introduction to the consumers did.Yes,I'll admit, some of the newer ceramic top ranges,bottom mount freezer refrigerators,dishwashers and all the front loading washers far exceed the performance and some the quality of the old line of true FRIGIDAIRE appliances but none of us will ever know how well or how horibly FRIGIDAIRE's version of the current major appliances made today would have scored.My own opinion would be a more positive one.Yes,another admision of mine,the current line Frigidaire (Electrolux)has available now has excelled in sales,quality and performance.Now farther ahead in their quest for success than they ever were after the take over from GM to WCI.I wonder if they would be where they are today had Electrolux not bailed them out.There are pros and cons here,However,I would buy a new Frigidaire front loading washer over a GE,Sears Kenmore,Amana,Samsung,Maytag,Whirlpool,or KitchenAid.The only front loaders I prefer over them are L.g. and Speed Queen.I know there are many others here who are not that sold on L.g. but I sold thousands of them and had very few disatisfied customers. My customers who bought the L.g.dishwashers,refrigerators and electric ranges and had issues were the ones that were disatisfied ones.Not because of the problem at hand but the extreamly poor service they received. I haven't been selling L.G for a few years now so I am not aware of the improvements,if any that L.G has made in their previously unexceptible poor customer repair service.hopefuly,L.G. has improved that and moved forward.
