Hi,
Here is an extensive article from appliance express website on F7 error.
https://applianceexpresstx.com/oven-repair/how-to-fix-ge-oven-f7-error-code/
It lists all models that are covered by the article as well.
Just follow the instructions on each section to narrow down the problem part or read the article and decide if you would rather call a technician.
Hope this helps
