Great Forum and lots of great info!

I used this forum to troubleshoot and partially repair my micro but I've run into a snag with the UIB being unavailable. Wondering if there are any circuit board repair facilities for the UIB board: WPW10391271. The part number on the board itself is: 4619-646-99001.

I got the dreaded F9.Q code and replaced the door control assembly (WP8206635). After replacing, then I get the super dreaded F2.Q1. The fan/lights don't work after the F2.Q1 so think next step is replace the UIB. That part is unavailable from every place I contacted, ~10 of them and no one can get one. I've check connections, wire integrity, clean connections, etc.

I've done a bit of searching and can't seem to find a facility that lists the UIB for repair. I've sent an email to fixyourboard.com with no results back yet.

Any assistance/ideas would be terrific!

I don’t see any available either. Being mostly surface mount parts, there are unlikely any board level repairs.

Oh geez ... I'm unfortunately motivated because the granite backsplash is cut to accommodate this micro.

I can already see the progression ... micro dies and must replace, now backsplash will have to be replaced. Since new backsplash, why not get new counter tops. If new counter tops, then cabinets probably should be updated. New cabinets won't look right without new flooring. Full kitchen remodel because a board in micro can't be repaired! Oh my ...

Hail Mary time ... anyone with an option for the UIB?

Short update - found a company in Austin Texas that repaired the circuit boards: FixYourBoard.com!!!

I sent in my keypad, UIB, and relay board. They did their magic and it now works as it did when new! It's been only 5 days of it being installed and working so I'll post again in a few months or so. Hoping for the best as there are no other options that I could come up with.

Jessica at fixyourboard.com was terrific to work with. I happen to be passing through Austin so I got to see their facility and meet people in person for a change.

Hope this helps folks who may run into the same issue.
