Update Norcold 1201LRIM jumpered thermostatic switch

Fridge has been "on" since October, except that we usually turn it off when driving because we don't usually drive with the propane on. parked here for three months with fridge on except for a couple of hours last week when I de=iced one side of the freezer.

We can usually hear the fans when seated at the dinette and hear them turn off and on when opening and closing the doors. Now no change in sound.
