GE Oven Trips Breaker When Bake Element Screwed To Back of Oven

Question

If I unscrew the bake element from the back of the stove so that the metal plate on the bake element (almost identical to this: https://www.lowes.com/pd/Certified-Appliance-Accessories-Replacement-Oven-Bake-Element-for-GE-and-Hotpoint-WB44K10005/5001581763) does not touch the back of the stove it works fine and does not trip the breaker.

However, if that metal plate touches the back of the stove it trips the breaker if we try and use the bake function.

Model: GE J BP23D R3WW Bake Element is: WB44T10060

This is where the element screws into the oven: I'm reusing the same screws with the new element.

Any idea where to start?

Edit: I double checked the screws in the back of the oven and can confirm that the screws are not coming into contact with anything other than the insulation:

Note: I know my black and red are swapped (i.e. source red does not match oven red), I was doing testing

Answer 1

A breaker with a TEST button means it's a GFCI or AFCI device. Those can't be used on a circuit where the Neutral (white, usually) wire is connected anywhere to ground. It appears from your photo that the green equiment ground wire may be connected to the neutral tab of the range wiring bar. You need to remove the green wire and connect it to the stove chassis - there will likely be a green screw nearby for exactly that purpose. Any connection to the stove chassis from the stove neutral wiring will cause those kind of breakers to trip.

Answer 2

I am assuming it worked as it was connected. It appears you have a shorted element. IE. the resistance element is touching the case. This can be checked with an ohm meter. Power must be off before proceeding. Remove the wires from the element power terminals. Measure resistance between terminals and ground, you should not get a reading, if so you have a bad element. If you get no reading measure between both element terminals and if you get no reading you probably have your meter set incorrectly.
