Resistance level does not change anymore. What is
I fixed a problem with my Schwinn Elliptical 430 resistance level not working. When I would change the level anywhere from 1-16, I could hear the motor turning, but there was no change in resistance. If you hear the motor moving, then try this:
Using a Phillips screwdriver, remove all the screws on the left side of the large plastic cover (left side if you are standing on the machine). When all screws are removed, you can pull the plastic cover off, and move it towards the back of the machine without having to disconnect any of the metal bars. (The bottom two screws are a little tricky to get off. Hold the housing in place, don't let it sag, in order to get them out.
Look inside the unit and find the magnet, which is a rounded, brake-show like piece that is close to the flywheel, on the top half of the unit. There's a cable from the motor that goes upward and is attached to the magnet housing.
If you try to adjust the resistance level now, you should see cable move up. This is supposed to allow the magnet to move closer to the flywheel and increase resistance. In my case, the magnet was stuck and wouldn't move upwards. When I gave the magnet a little push with a screwdriver, it popped up to where it should be.
To solve this issue, you will need two wrenches. You must go to the opposite end of the magnet, towards the front of the machine, and you will see it's connected with a nut & bolt. Using a couple wrenches, hold the bolt, and loosen the nut about 1/4 turn.
This should lessen the pressure on the magnet housing and allow it to move freely and not bind. Reassemble everything. Lie the elliptical down on it's side to allow the screws to fall into the holes easier.
Once it's all back together, you should find that the resistance level works again!
