Product review (5 stars): Fits dryer DPSB620EC3WW as well.
This actually will fit a GE model DPSB620EC3WW dryer although it is not listed for it nor does it show up in any parts lists for that dryer.  Turns out it IS listed for a DPSB620EC2WW which as far as this is concerned is the same dryer.  Fits perfectly.  The alternative was to buy the inside door that had the gasket attached - for over $70.
