General Maintenance Action
Aircraft; Procedure
We completed a normal preflight and pushed back off the gate. After push back and engine start I noticed that the cabin pressurization display was showing all amber dashes on the cabin rate display. I called Maintenance Control from my cell phone. I was directed to pull out and reset 2 circuit breakers. The circuit breaker reset brought back the missing indications. I told the Maintenance Controller that the reset worked and asked him if he wanted to put the reset in the logbook. I probably should have asked if doing that reset was a 'required' logbook entry; because his answer was not definitive. I'm never sure what maintenance items require a logbook entry or not; so I always ask what ever mechanic responds if there needs to be a logbook entry. I get mixed results on the subject that keeps me asking. So when asked if I wanted to log it; I replied by saying it doesn't matter to me. It's a maintenance item. In hindsight the subsequent flight had a pressurization failure that required an emergency descent with a declared emergency. Now I'm second guessing if the reset required a logbook entry. Though I'm still not sure.
EMB145 Captain reports a pressurization display anomaly after pushback which is corrected by pulling two circuit breakers at the direction of Maintenance Control with no logbook entry. A loss of cabin pressurization event occurs on the subsequent flight requiring an emergency descent.                                  See ACN 1125914
