## Discrepancy

DURING FLIGHT, SMOKE EMITTED FROM THE 2-7 OVEN AS IT OPERATED HOTTER THAN THE MEDIUM SETTING CAUSING THE SMOKE ALARM TO ACTIVATE. THE OVEN WAS TURNED OFF AND THE CIRCUIT BREAKERS PULLED AND THE SMOKE DISSIPATED SILENCING THE SMOKE ALARM. AIRCRAFT CONTINUED TO DESTINATION AND LANDED WITHOUT INCIDENT. REPLACED THE OVEN AND OVEN CONTROLLER. OPERATIONAL CHECK GOOD.
