Product review (5 stars): This was a perfect fit for Whirlpool Duet GEW9200LL1 dryer
This was a perfect fit for Whirlpool Duet GEW9200LL1 dryer. The part seems to be OEM. It was stamped "FSP" and the part # "3387747, 5400W, 240V". It's been working fine for the past month. On a side note: The dryer has worked great for the past 10 years. When it did not provide heat, I diagnosed the problem to be the heating element. When I opened the front panel, this was the first time it was opened in 10 years. When I opened it, I could not believe how much lint had accumulated in the bottom of dryer. It was everywhere  in big clumps and sheets. It's amazing how it didn't catch fire. We clean out the lint trap on a regular basis so this was very surprising. Upon discovering this, I made a mental note to clean out this area with a vacuum every year of so.
