Nordic Track A2250 Pro stuck inclined

Check that the incline plus switch is not jammed or likely there is a defect in the panel circuit causing plus incline to be repeated. This needs to be trouble-shooted by removing and testing the panel circuit.

call the technician from the maker

have the card checked.. see if its going bad..

Plug the power out and plug it back in after a count of 50 could be that it needs to be reset .then plug back in the power and see what its doing if no luck go to manual and look for reset

God bless you

the motor controller is bad and needs replaced

I had the SAME problem, several time, with my NordicTrack A2250 Treadmill.
Allow it to go fully up and then fully down several times, without turning it off. IT seems to "cycle" that way 3 times and then "reboots" itself and starts working normally, again.
I had to figure this out myself... none of the suggestions I read worked.

I know it's been months, but, if you still have this problem try this: 1. remove the philips screws holding the motor/belt/electronics cover on: you can lay the whole thing on it's side and remove them from the bottom. there's two in the front and two on the sides.
2. Obviously, unplug the unit! before doing anything. lay the unit back on it's feet (normal position)
3. Find the incline motor assembly. it will be int he middle of everything. black tube thingy.
4. take a cordless drill with a flat head screw driver bit, and turn the incline motor CCW. until the bed is flat.
5. what what I have read, you should shop for a new incline sensor. these fail before the motor does.
