## Discrepancy

AT 36000 CABIN ALTITUDE BEGAN TO CLIMB AFTER CONTROLLER WAS WORKING FOR ONE + HOURS.  RATE OF CLIMB SUCH THAT HABITUAL LEVELS COULD NOT BE MAINTAINED W/O DESCENT TO LOWER ALT, AUTO SYSTEM WORKED GOOD AND SCHEDULED DIFFERENTIALS AND ALTS MAINTAINED AS DESIGNED.  REMOVED AND REPLACED DIGITAL CONTROLLER AS PER EMB AMM 21-31-01.  OPS GOOD.  AIRCRAFT RETURNED TO SERVICE.
