Kirk for Model Number MER5875RAS I determine whether the reason my inner burner on my triple burner (front right) is due to the element itself or the infinite switch. Upon inspection of the burners I notice several cracks in the ceramic dish that the element is mounted in. Is this customary? The other burners have no cracks. How can I check to determine which is the faulty part. The outside 2 elements work fine it is just the innermost element that is not coming on. There are two or three cracks....one going across the entire element ceramic pan.
Answer Kirk, You'll probably find that the triple burner is the burner you use the most, and the insulation material does react to heat and usage, but doesn't usually cause any effect on the operation. You can test the element ribbons with a VOM meter, using the common terminal, (closest to the sensor box) and checking from that terminal to the remaining three(3) terminals on the side of the burner housing, you should read a "closed" circuit on all three tests, if all's OK the element(s) are good. You'll most likely find that you have a faulty triple burner rocker switch 7403P985-60 circuit or a damaged wire. You can also check the rocker switch circuit with a meter as well. Read More...
