## Discrepancy

CREW NOTICED THAT THE CABIN WAS NOT PRESSURIZING AND LEVELED OFF AT 8000 FEET TO TROUBLESHOOT.  CYCLED AUTO/MANUAL SWITCH WITH NO SUCCESS. DID NOT DECLARE AN EMERGENCY AND RETURNED TO LAND WITHOUT INCIDENT.  MAINTENANCE FOUND THE TOP PROXIMITY SENSOR ON DOOR HAD A CUT WIRE WHICH CAUSED THE DOOR TO SHOW OPEN AND NOT ALLOW DOOR SEAL TO PRESSURIZE.  MAINTENANCE R & R THE MAIN CABIN DOOR SENSOR IAW AMM AND OPS CHECKED GOOD.
