## Discrepancy

MOTOR MOUNT STUDS PULLED OUT ENABLING FAN TO JAM.  MOTOR OVERHEATED AND PRODUCED ELECTRICAL SMOKE IN CABIN.  CIRCUIT BREAKER FINALLY POPPED.  PROBABLE CAUSE WAS EITHER OVERTORQUE OF MOTOR ATTACH NUTS OR DEFECTIVE CASE ON EVAPORATOR ASSEMBLY.  THIS WAS AN ORIGINAL INSTALLATION NO PREVIOUS WORK HAS BEEN DONE ON THIS SYSTEM.
