Why does the Radiant surface element (15b- on diagram) outer layer heats up but the not the inner or middle part. Why is that? Do I need to replace the whole radiant surface or is there something minor I can reset to make it work again?
Answer Sonny, If the issue is in the radiant heater in the burner, yes, you'd have to replace the complete burner assembly 316418400. But you would want to test and verify the dual infinite switch circuits 318120521 The switch has separate circuits for power to the inner element and the outer element. If the P2 to 4 circuits on the switch have failed, the inner element will not operate. You may want to test or replace the infinite switch first.
Is there a video or YouTube for replacing the Dual element with part number 316224300 or 316418400?
There is not a video showing how to replace the Dual element for your unit. To get lift the top you will remove 3 screws from the door opening that hold the main top in place and lift the main top and pulling forward slightly. Disconnect the wires and flip the top over. Remove the bracket holding the burner in place and remove the burner and install the new one. The wires should be the same connections.
Can I use 316418400 to replace the dual radiant element on a Frigidaire GLEF378ASE?
