Norcold N621 fridge has no 12V power to board or panel

Believe my box was built before the recall. Checked the recall site this morning. Did not see a red LED light - will look again.

Checked DC panel fuses, as well as the 3 amp fuse in control box - all good. Was able to pull the cover without disconnecting wires

One thing I checked was the 12V leads going to the box - nothing on my meter. Did have AC power to the outlet on generator power.

Checked both batteries - full charge.
