Narrative:

One of the display cooling fans was deferred. The write-up was very vague as to which one was deferred. Also the circuit breaker was supposed to be pulled and collared. It was not. We then had a problem with the other fan and had to call maintenance to find out the problem because the proper circuit breaker was not pulled. After we found that out, we then did the abnormal procedure and continued to our destination as filed. The problem was maintenance did not do the first deferral properly.
