If pedal resistance sticks on one setting, the resistance motor could be defective. Many elliptical exercisers offer workout programs that vary resistance automatically during the routine. If resistance during the uphill climbs on a pre-programmed workout feels the same as the downhill treks, try manually changing the resistance. If you can change resistance manually, then you'll need to replace the console.
Most elliptical exercisers use battery power to change resistance, so checking for DC voltage going to the resistance motor is safe and easy. If batteries power your elliptical's control system, use a multimeter to measure voltage at the resistance motor when you manually adjust resistance on the console. Replace the console if it doesn't send voltage to the resistance motor when you manually change resistance. Replace the resistance motor if it doesn't run when getting voltage from the console.
These repairs may help solve your elliptical machine problem
Replace the elliptical resistance motor
The resistance motor changes the distance of the C-magnet from the flywheel to adjust the pedal resistance. If the resistance motor doesn't move when activated, replace it.
If pedaling your elliptical feels the same at every resistance setting, the resistance motor could be the problem. This repair guide and video show how to replace an elliptical resistance motor in 30 minutes or less.
The console displays the elapsed time, distance traveled, estimated calories burned, current speed and the user's pulse. If the console doesn't light up, replace the battery. If the problem continues, replace the console assembly. The console also controls the resistance motor. Replace the console if it fails to adjust the resistance motor.
If your elliptical console won't turn on or if the console display isn't working, the console might be broken. The DIY repair guide and video show how to replace an elliptical console in 3 quick steps.
