I have a NordicTrack C2155. Incline not working. There is a schematic inside. There are red, white, & black wires from the circuit board to the incline motor. Unplug the treadmill and have a licensed electrician construct a flying lead cord with a male spade on neutral and female spade plug on hot. Connect neutral to white and hot to where either red or black were connected. Plug in to see if the motor runs. Careful to remove power when the incline reaches its limit and reverse direction. If the motor runs in both directions, the motor is good. Follow the black two conductor wire to the circuit board and unplug from board. Check continuity across this switch. Run motor and this should toggle off and on. If all this checks out then the problem must be with the circuit board. On my treadmill, the schematic says that +5v should supply the sensor, but I only get +3.3v, which is TTL level. The drive motor sensor supply is +5v. The incline motor doesn't even show a sign of trying to run. Either the output transistor is burnt out or the low voltage caused an error so that it does not try to run the motor. Either way, I'm quite certain that a new controller board will remedy the problem.

Hello, it’s never a great sign when the machine powers up but the belt doesn’t turn over. best case scenario is it has blown a fuse on the lower control board. With the motor cover off and using a torch you should be able to locate the fuse (about 15mm long) on the lower board, a blown fuse will look broken or blackened. If the fuse looks ok then it’s very possible the damage is coming from the lower board and will need replacing. Quite often this will have a burning smell.
Oh, another idea. Is your safety key in?

It would appear via one video and someone else's post that it is at the front of the machine, directly above the crossbar that contacts the floor.

My treadmill won't stays in the incline position can't get it to come back down

My treadmill has a little steel rod that flips in and holds the bed up' When you want the bed down you pull the rod back out and it lets it come back down.

Got beeping? I JUST figured out how to fix it. Take the console apart and pull the connector from the back of the iFit card adapter. Plug back in, should be good as new!

Have you ever found the answer to this problem?

Sounds like the overlay on the console has stopped working. If you get beeps on all buttons but not the ones in question, this will need replacing. It’s quite an easy job once you have the parts. Try eBay or the shop you got it from.

check to see if there is a smaller board in the unit. There maybe relays between the main board and the motor.

GO to Nordic track website and look under support. It should direct you to what error codes mean.

Most buttons (all but incline 6 through 12) on my C900i stopped working all of a sudden. Long story short... it was the ribbon cable connections on the back of the control panel. Its 6 screws to get the panel off, and then 10 screws to open the panel. Cut the zip tie so the connection wires can be pulled through the hole in the back panel cover. And then take the iFit module off after you open the panel to allow fully removing the cover. The little white piece on the ribbon cable connectors slides up to allow the cable to slip out. Search youtube if you've never dealt with ribbon cables/connectors - they're very common in electronics. You can also search for how to clean the cables. In my case, simply disconnecting/reconnecting was all I had to - this fixed every button on my panel.
