How to fix your Stairmaster 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.

Maintenance tips for your Stairmaster stepper

• Inspect all parts of the stepper before each use.
• Tighten any loose screws, nuts, bolts, pins or fasteners before using the stepper.
• Replace any worn or damaged parts on the stepper immediately.
• Lubricate all moving parts on the stepper regularly using all-purpose grease.
• Replace the batteries in the console when the console appears dim or it's completely dead. You may also need to replace the batteries when resistance won't change or changes in resistance are sluggish.
