Product review (3 stars): 2cnd one in 6 yrs.
Seems the life span of these parts is VERY limited. So far the best I have seen is 3.5 years.  Good thing we are selling the house and the microwave is a built -in so it stays. Good luck to the next owner. Had a GE microwave that lasted 13 years and sold it in garage sale (still working) but this one - not so good! The replacement part works fine presently but I doubt it will last more than 3 years. Installed in a Maytag Microwave.
