Macerator Toilet Relay P/N: 602302-04
Here is the part number for the macerator toilet relay. In particular this is the one in the FC 26U (RBQ/RBT), I assume they use the same macerator in all Airstream but not sure on that, again, that is an assumption on my part. Trust me if you have the macerator you will want to get a spare relay. Ask me how I know...We lost ours at the Urban Air - Logan, OH rally. If it goes out you cannot use/flush the toilet. You can get them from your Airstream dealer and they're around $20 dollars. Money well spent.
