1984 Airstream Trailer Service Manual page H-16. Control Panel Removal 1- Remove main 50 amp fuses from 12 Volt
Distribution Panel. 2- Using care not to damage the surrounding cabinet, gently pry the control panel out. It is hald in place with spring clips that snap into position. 3- Disconnect main harness. 4- Reverse procedures to reinstall. There you go also elsewhere in the manual the pink wire is the one that powers the panel. My 86 has the same stuff the 84 manual calls for. Hope this helps you somewhat. Could be the thermo breaker is faulty. loose wires etc.
