Maybe I shouldn't ask questions here..
Don't mean to be rude, but you are correct.
Repair questions should be asked in one of the repair boards.
This board "Service Calls" is a place for technicians to share information on repairs they have already made.
I also don't have any experience with sub zero so I left the topic for someone else with some experience with the brand to answer.
Anyway we don't alway have all the answers, so feel free to help us out by posting a update as to how the repair goes.
Maybe you will have some tips to share with us.
Thanks for posting.
