After rotation we received a Landing Gear Air/Ground Fail message on the EICAS. The First Officer called positive climb and I called for gear up. The gear would not come up so I told him to push the down lock release button and pull the gear up. The gear retracted and the Landing Gear Air/Ground message went away. We performed the after takeoff checklist followed by the QRH for Landing Gear Air/Ground Fail message. The QRH told us to continue the flight; avoid ice and contact Maintenance. We contacted maintenance and informed them that we had the message appear but it went away. They told us to continue to destination. On approach we put the gear down and the message reappeared about a minute later and stayed on the rest of the flight. On our next flight during cruise I again reviewed the QRH for the Landing Gear Air/Ground Fail message. I found three pages before a checklist for gear lever cannot be moved to up after takeoff. I reviewed this checklist and found we had not complied with it. This is when we determined that the event occurred. During climb out I decided to retract the gear believing it was an air ground failure issue. I recalled the button was to be pressed when the gear would not come up so we did. Using the MENA checklist order we performed the after takeoff checklist first then went to the QRH for the abnormal checklist. Please add a link between the Landing Gear Air/Ground Fail Checklist and the Gear Lever Cannot Be Moved To Up After Takeoff Checklist in the QRH.
After rotation we received a Landing Gear Air/Ground Fail EICAS message. I called positive rate. The Captain replied; 'Gear up'. When it wouldn't go into the gear up position I told the Captain. He replied push the downlock release button and select the gear to the up position. There after the landing gear retracted and the Landing Gear Air/Ground Fail message went away. After the gear up After Takeoff Checklist we did the QRH Checklist for the Landing Gear Air/Ground Fail message; contacted Maintenance and were instructed to continue on to destination.During the next flight the Captain was reviewing the QRH and discovered the checklist for the gear not retracting checklist. I was instructed to push the downlock release button. Following the After Takeoff Checklist I continued on to the Landing Gear Air/Ground Fail message checklist and focused on the instructions to contact Maintenance.
EMB145 flight crew receives a LG AIR/GND FAIL EICAS message after rotation and the gear lever will not move to the up position. The Captain asks the First Officer to push the down lock release button and select the gear to the up position; which is successful and the LG AIR/GND FAIL message goes away. The crew later discovers that a QRH procedure exists for the gear handle will not move to the up position and that pushing the down lock release button is not part of it.
