No, the 621988 doesn't fit the "V" models, so it won't work on the N811VF. The original N811V board runs LP and AC automatically, and the V boards are discontinued. If the new power board didn't fix the switch to electric, the optical board is likely the cause, and the Norcold N8X is the replacement fridge.
