- That particular motorhome did have a 3 way fridge as original equipment from the factory. Also, the wiring diagram in the 1984 Airstream Motorhome Owners Manual shows a 25 amp fuse on the chassis fuse block that powers the wipers
and the refrigerator
- First thing I'd do is confirm that the fridge is actually receiving power from the chassis fuse pannel. To do this first check to see if the wipers are working (as I mentioned above the fridge and the wipers are on the same fuse). If they are then you know the fuse isn't blown. Next I'd check the wires at the fridge to see if you are getting power from the chassis fuse block (seperate from the ignitor run) which should come from the coach battery. If you have power on the chassis wires then you know it's the fridge.
Let us know what you find. If power is confirmed someone else on the forum will need to jump in and help with diagnosing the actual refrigerator 12V
