Jd for Model Number mer5755qaw why don't the parts lasts longer anymore .we had this part replace about two years. the part is the hidden bake element
Answer JD, I really can't explain the life expectancy of parts, I'm sure there have been changes over the years, but thats proprietary information for the manufacturers. As for the element, to the best of my knowledge, they are still produced by the same manufacturers the product builder has always used. and most failed elements are due to some type of usage issue. 2 years is a bit short for a hidden bake element,in my opinion.
