Product review (1 stars): Don't trust the model to part look-up
I ordered this after accepting Amazon's model to part number look-up recommendation.  Unfortunately, it was not correct.  Would have been better to see the electrical connection side of the timer on the Amazon photo and then I would have known.

 Amazon, for future reference, the actual part for GE model DDE7900SBLWW dryer timer is WE4X791.

Not a huge deal -- but the dryer is in a rental property halfway across the country and my renters now have to wait while the second part arrives and I can arrange installation...

Next time I will take extra care to shop by part number.
