Product review (5 stars): Not a Whirlpool FSP Element
From the description, the buyer is led to believe this is an actual Whirlpool part. The box it comes in has  label that has " DRH10" then below that you see "Whirlpool Dryer Heater 3387747". This label also has a logo that says "Quickpartsdelivery.com". Other than this label, there are a couple of others with a barcode and numbers. I could not find anything about the manufacturer and there was no included paperwork. The element plate itself is not stamped with the number or anything as was found on the original part. With all this being said, this part does appear to be well made a fit perfectly. It took maybe 10 minutes to slide it in place and tighten down the side screw and 2 bracket screws. I flipped the breakers back on and had heat within just a few seconds. I then went outside to the dryer vent outlet and felt the heat blowing through with a minimal of the "burnt" smell that usually comes with the first run of a new element. This smell was gone within a few seconds and by the time I got back inside to open the dryer, there was no smell at all. I do plan to keep a close eye on it though for the first few loads that I dry. If this element fails, I will write an update, but for now, I'm keeping my fingers crossed and hope to get a few years service from it.
