Product review (1 stars): WARNING: do NOT buy this product!  It has a known manufacturing defect.
This oven series (this model and many others like it) made by Whirlpool has a well-known and documented manufacturer's defect.

When you attempt to use the self-clean feature, the oven fails afterwards and the repair requires a technician's visit and a new part.  This happens EVERY time you use the oven's self clean feature.

See this lengthy thread to read about just a few of the problems evident over YEARS of the product's availability.

Do NOT buy this product UNTIL this well-known manufacturer's defect has been corrected.
