Narrative:

Climbing out of lga; noticed aircraft pressurization problems. (Excessive pain in ears; looked over and saw the cabin pressure was climbing rapidly and excessively. Then cabin ceased to climb anymore). Coordinated with ATC to level at a safe altitude of 10000 ft and vectored in terminal area to problem solve. I contacted dispatch and maintenance control to work through the abnormal pressurization problem since there were no messages or specific QRH procedures for the condition. I contacted maintenance control so they could help problem solve with us and direct a course of action. All they asked was: do you have any messages or door open indications? None were indicated. I asked for their recommendations/thoughts and they directed me to perform the QRH. I told them given the circumstances there wasn't a clear QRH procedure to perform. The closest procedure was 'unpressurized flight with packs on.' they directed me to perform the unpressurized flight with packs on QRH procedure. I asked them several times to make sure that is absolutely what they wanted us to do. They said 'perform the QRH.' I did as directed by maintenance control specialists. I contacted maintenance control to problem solve and feel they led us down an incorrect path by insisting I perform the QRH procedure without ever trying to problem solve or diagnose the problem. This ultimately resulted in the cabin climbing excessively and having to initiate a descent and return to lga. No assistance was required. It was a safe; normal and uneventful landing at lga. Maintenance was performed and we later flew the aircraft with revenue as planned.

Title: CRJ200 FAILED TO PRESSURIZE AFTER TKOF. FLT CREW RETURNED TO DEP ARPT.

Narrative: CLBING OUT OF LGA; NOTICED ACFT PRESSURIZATION PROBS. (EXCESSIVE PAIN IN EARS; LOOKED OVER AND SAW THE CABIN PRESSURE WAS CLBING RAPIDLY AND EXCESSIVELY. THEN CABIN CEASED TO CLB ANYMORE). COORDINATED WITH ATC TO LEVEL AT A SAFE ALT OF 10000 FT AND VECTORED IN TERMINAL AREA TO PROB SOLVE. I CONTACTED DISPATCH AND MAINT CTL TO WORK THROUGH THE ABNORMAL PRESSURIZATION PROB SINCE THERE WERE NO MESSAGES OR SPECIFIC QRH PROCS FOR THE CONDITION. I CONTACTED MAINT CTL SO THEY COULD HELP PROB SOLVE WITH US AND DIRECT A COURSE OF ACTION. ALL THEY ASKED WAS: DO YOU HAVE ANY MESSAGES OR DOOR OPEN INDICATIONS? NONE WERE INDICATED. I ASKED FOR THEIR RECOMMENDATIONS/THOUGHTS AND THEY DIRECTED ME TO PERFORM THE QRH. I TOLD THEM GIVEN THE CIRCUMSTANCES THERE WASN'T A CLR QRH PROC TO PERFORM. THE CLOSEST PROC WAS 'UNPRESSURIZED FLT WITH PACKS ON.' THEY DIRECTED ME TO PERFORM THE UNPRESSURIZED FLT WITH PACKS ON QRH PROC. I ASKED THEM SEVERAL TIMES TO MAKE SURE THAT IS ABSOLUTELY WHAT THEY WANTED US TO DO. THEY SAID 'PERFORM THE QRH.' I DID AS DIRECTED BY MAINT CTL SPECIALISTS. I CONTACTED MAINT CTL TO PROB SOLVE AND FEEL THEY LED US DOWN AN INCORRECT PATH BY INSISTING I PERFORM THE QRH PROC WITHOUT EVER TRYING TO PROB SOLVE OR DIAGNOSE THE PROB. THIS ULTIMATELY RESULTED IN THE CABIN CLBING EXCESSIVELY AND HAVING TO INITIATE A DSCNT AND RETURN TO LGA. NO ASSISTANCE WAS REQUIRED. IT WAS A SAFE; NORMAL AND UNEVENTFUL LNDG AT LGA. MAINT WAS PERFORMED AND WE LATER FLEW THE ACFT WITH REVENUE AS PLANNED.
