Welcome to Just Answer.
Sorry to hear about your problem.
F1 - E2 fault code means you have UL A/D error(s). You need to perform the following test:
1. Disconnect power for at least 30 seconds.2. Re-apply power and observe for at least one minute.3. If code re-appears, replace the control board (also called ERC or clock).
If you need further help or clarification on this answer, please do not hesitate to reply to this post.
Thanks for asking your question at Just Answer.
Best of Luck, Brian
Please leave feedback at your convenience.
Can you tell me the part number for the control board?
Thanks again, Lee
