JBP84TOHWW GE Electric Range Large Dual Element Not Working

Either the knob has gone out or the burner element. I would test the knob first to see if there is current when turned to the large zone. If the knob is working, next would be to test the burner to see if the outer ring has burned out. I would guess more likely the control has gone out. Burners have less failure (typically).

You have to access the underside of the cook top. Does the back right work correctly? If so switch the wires on the back left to match the right burner.

Most probable cause is a failed element

Does yours have the (small large burner switch)? If so, try switching it back and forth. It could be defective or your small burner element is bad.

It is the burner control (behind the knob). The triac in the control has failed. $50 item, 10 minute change. Just make note which wire goes to which terminal.

I doubt that it is the control board, as the board has little to do with the stove top, but rather controls the display and the oven temperature/feedback monitoring.

Hope this helps.

If the burner is scorched or pitted, go ahead and replace it. New burners can cost anywhere from $10 to $40. Otherwise, check the burner's electrical connections to make sure there is solid contact. Jiggle the burner in its socket. If it is loose, then remove the burner—most just pull out of the electrical socket, although some are mounted with a screw. (Always unplug the range before removing a burner.) Slightly spread the two terminals apart for a tighter connection. If it still doesn't work, then replace the faulty burner with a functioning burner of the same size. If that burner works, then replace the bad burner with a new one. If it doesn't, then inspect the electrical socket for damage. If it's charred, replace the socket. To do so, remove the screws that secure the socket to the range and then unscrew the range wires. Attach the wire connections of the new socket to the range wires and reassemble the burner.

you need a new switch that is in the control panel

What holds the spring assembly onto the bar assembly is just two small prongs. Use a pliers on the end that protrudes through the bar, squeezing the prongs together, and it should come out fairly easily.
