How to fix your Nautilus stepper when resistance won't change

If pedal resistance sticks on one setting, the resistance motor could be defective. Many steppers 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 likely need to replace the console.

Most steppers use battery power to change resistance, so checking for DC voltage going to the resistance motor is safe and easy. If batteries power your stepper'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.

What to do when the console won't power up on your Nautilus stepper

Dead batteries, a failed power supply, bad electrical connections or a faulty console can prevent the stepper console from turning on. If your stepper is powered by batteries, change the batteries to fix a dead console. Replace the batteries during routine stepper maintenance to keep the console powered up. If the console doesn't light up after replacing the batteries, you'll likely need to replace the console.

If your stepper uses an electrical outlet for the power supply, unplug the stepper and check the power cord. Reconnect power cord wires if disconnected. Replace the power cord if it's damaged. If the power cord is intact and properly connected to the console, then you'll probably need to replace the console.
