AP 900 Dec frozen

thefamily90 Phillips

Hello all,
Much to my dismay, after getting up at 4:00 AM to view Jupiter I found the Dec gear was frozen. When using the keypad the scope moved just fine in RA but would not budge N-S. I loosened all knobs on the Dec axis and while I could forcefully move the scope N-S it is clearly frozen or certainly near so. What have I done??? Any thoughts?
