Just finished repair (cracked frame) and reassembly of Nordic Track 7000 R treadmill. The machine operated flawlessly prior to this repair but now the power incline runs through only a very limited cycle - I would guess between 0-3%. I've run the machine through the manufacturers calibration mode several times but with no success - it only recalibrates within that limited cycle. I thought I was very careful but could I have reassembled the machine in such a way to create this problem? This limited incline cycle runs smoothly and with no apparent mechanical impediment or strain. Any suggestions would be greatly appreciated. BTW the model is NTL2295.
