Wasnt completely sure this would match at first since the control panel stopped responding randomly. Thankfully connector alignment matched better than expected and everything is working again.

Picked this up because the buttons were no longer reacting correctly. Connector alignment matched better than expected. Unit completed a full cycle without issues. Repair turned out easier than expected honestly.
