## Discrepancy

RTFL DUE TO CREW REPORT OF SMOKE IN THE CABIN.  [SUP 05-04-07]  SOURCE OF SMOKE WAS TRACED BACK TO A DEFECTIVE COFFEEMAKER IN THE AFT GALLEY. IT WAS DETERMINED THAT A FAULTY HEATER POWER RELAY CONTINUED TO SUPPLY POWER TO THE TANK HEATER ELEMENTS EVEN THOUGH THE CONTROL CIRCUITRY COMMANDED THE HEATERS TO BE TURNED OFF. PRIOR TO THE TRIPPING OF A SAFETY THERMOSTAT, THE SMOKE POINT OF THE POTTING COMPOUND ENCASING THE WIRING WAS EXCEEDED CAUSING SMOKE TO BE RELEASED INTO THE CABIN.
