Bill L. for Model Number MER5770AAA I have had to replace the 8 inch left rear burner and the dual 8 inch right front burner, because the elements had no continuity and could see the breaks. The two 6 inch burners and the dual 8 inch right front burner work just fine now.The problem is the left rear 8 inch burner does not come on at all and checked at terminal and do not have full voltage. I suspect the infinite swicth for that burner is bad?? Can you help ? I do think the infinte swicth is bad. Thank you
Answer HI Bill. Check the corresponding infinite switch L1 and L2 input voltage for 240vac. If it is there,then you will need to see if you have 240vac output at H1 and H2. If you turn the sw. on mid point, you should get this output. Then you will need to go to the burner and check for 240vac at the purple wires. Then disconnect the power and ohm the wires from the switch to the element to insure continuity of the wires. The infinite switch is part # WP7403P239-60. Thank you. Read More...
