Product review (2 stars): Sizing is Off
I purchased this to repair my dryer, used the correct model number and color-code guide, but it was about 2 inches too big.  Luckily, I'm handy with a sewing machine and took it down so it would fit.  It was easy enough to glue in place and it seems to be doing its job just fine.  Just be aware that it may not be the diameter you actually need.
