Review on Ultra Durable 131965300 Dryer Timer Knob Replacement Part By BlueStars - Exact Fit For Frigidaire Electrolux Dryers - Replaces 131666601 131666604 131666606 - Pack Of 4 by Kyle Earley

Unlike the stores' response that this would not work, i took the posted measurements and per my extrapolated calculations down to the mm of the D shaft, viola this item worked with my FRIGIDAIRE FWS777GFS0 WASHER DRYER which needed KNOB-Part Number 131858004. The knobs seem to match the original knobs material and size and included the internal metal ring that holds the shaft. Note the design flaw in the original and this is not having a reinforcing metal ring on the outside of the plastic shaft bore to support the plastic pressure point. I cannot yet state how durable this is as yet per the manufacturer's claim but will update how long these last.
