Product review (5 stars): My Frigidaire Gallery FGHD2433KF1 began to stop in the middle ...
My Frigidaire Gallery FGHD2433KF1 began to stop in the middle of the cycle and give the UO or VO (Vent Open) error.  I could open and close the door again and it would go for a few minutes longer but would keep returning the error.  I could get it to finish by cancelling and doing a rinse only.  This part replacement fixed the issue.  Very simple to change out.  Just unscrew the two screws that mount under the countertop, slide the dishwasher out, unscrew the nut on the top right of the inside of the tub and put somewhere safe, unsnap the wire holder and carefully remove the wire harness from the old vent and remove, and reverse the steps to reinstall the new part using the old nut.
