Same question. Different answers.
Ask both: "F720 on my GE range JGB735"
ChatGPT
The F720 error code on a GE range typically indicates a stuck relay on the oven control board. This usually means the control board needs to be replaced. You can try unplugging the range for a few minutes to reset it. If the error comes back, the control board is likely faulty. Replacement control boards can be found through GE parts retailers or Amazon. Make sure to get the correct part for your specific model.

In the example above, ChatGPT told you to replace a $200 control board. MyPros+ told you to check a relay first, a 2-minute test with a multimeter. That is the difference between guessing and diagnosing. One costs you a board. The other costs you nothing.
