SOURCE: error code 1 on schwinn elliptical 418

E1 error seems to indicate that the servo which controls the elliptical resistance is stuck. Here is how I fixed this (without using a "crank puller", which would be quicker by far).

You will need a very short phillips screw driver (snub nose), a long phillips screw driver, an allen key set, and crescent wrench.

- Remove the batteries from the unit.
- Remove the screws from the plastic housing (with the long phillips screw driver) on the left side. Do not forget the phillips screws at the front - they are smaller screws so don't mix them with the others. This will allow the plastic housing to flex and move around, but not come entirely off.
- Using the crescent wrench, remove the nut holding the left pedal to the crank. Carefully note the order of the washers on the crank attachment.
- Using the allen key, remove the little pedal attachment piece on the left crank arm.
- Using the short phillips screw driver, carefully reach inside the plastic housing on the top and remove the four screws holding the plastic plate on the outside of the fly wheel/crank. You will need to rotate the crank wheel to reach each of the four screws in turn on the inside of the case.
- Pull off the plastic cover for the wheel.
- Reinsert batteries and gently help the revealed cable (bottom) retract the magnet plate. In my case, the servo worked fine again after helping it retract the magnet plate that was somehow stuck/wedged.

Reverse steps to re-assemble.

SOURCE: My Schwinn 430 Elliptical is not changing

I think I am experiencing the same problem and have removed the shrouds. Are you experiencing a clicking sound while the unit is plugged in? All of this seems to deal with the servo motor. Don't be fooled by suggestions to replace the rpm sensor...this is NOT the problem. I am trying to find out what the initial setting for the servo motor and the tension cable should be. I found a site where you can order the servo motor, but it tells me that it could be months to receive this part. Sigh...

SOURCE: Schwinn 431 Elliptical doesn't register rpm's, distance, etc.

I have this same problem and called the customer service. The problem is that the rpm sensor is not working. It could be the sensor or something else. They had me check the connections first for the wiring harness at the top and middle and then sent me parts to work on the inside where I have my problem. I am still working on mine because the magnet was installed on the wrong side of the flywheel. Hope you don't have this issue.

My Schwinn 430 elliptical makes a clunking noise when pedalling backwards but not forward. What is causing this?


I have a iron man cdt elliptical that was clunking . I found a shaft on the end of the crank was slipping in and out, inside the bearings. I shimmed it and retightened the retaining washer which prevented it from slipping . Smooth as silk now. It was very frustrating because all seemed tight at first.

While using the elliptical there is a persistent knocking noice in the fly wheel area with each rotation. It seems to be at the bottom of the rotation. How do I fix it?


I just fixed the problem on my 430. Somewhere on this forum someone suggested that the dollar size cover on each side of the flywheel cover be removed and the bolt tightened. You will need a socket wrench. It took less than 5 minuted and whamo. Problem solved. Thanks to the individual with that input. Good luck

My Schwinn 431 Elliptical rpm sensor is not working. I talked to customer service and they sen me new parts and pictures. I'd call them today but they only work M-F. anyway, it looks like the flywheel...


I took a magnet from a magnetix toy and secured it to the correct side of the flywheel. It's working now...I just finshed doing it. Hopefully it'll continue working. Thanks for pointing out the magnet was on the wrong side.

When turned on makes clunking noise. I am able to use the machine when not pluged in. when the electrical display is on makes clunking noise


You may have to disassemble the unit remove the side panels if the foot pedal assembly, arm assembly bearing and bushing are in good shape. You'll have to inspect the flywheel and pulley assembly with the power on & off . It will be a process no doubt.

The flywheel is becoming uneven on one side and making noise while rotating. I don't see any where I can adjust the bolts. Any tips?


reove the center black plug and tighten bolt. If this problem has persisted then the crank hub shaft could be worn and need to be replaced. If the plastic is seperating then a screw inside has come out or broken. They are accessed by removing the covers from the opposite side. you may be able to get to them without having to purchase a crank puller and remove crank weldment.

Follow this link for step by step instructions. Note you will need a crank puller which you can purchase at most bike shops. remove both covers then crank weldment(discs).
