Frequently Asked Questions

Why does my NordicTrack keep showing error code E7?
Error code E7 typically appears when the safety key isn't making proper contact with the console sensors. This can be caused by a dirty or damaged safety key, debris in the key slot, or a worn-out key that needs replacement.
Can I use my NordicTrack treadmill without the safety key?
No, you cannot use your NordicTrack treadmill without the safety key properly inserted. This is a mandatory safety feature designed to immediately stop the belt if you fall or step off the treadmill unexpectedly.
How do I get a replacement safety key for my NordicTrack?
You can order a replacement safety key directly from NordicTrack customer service, through their website, or from authorized fitness equipment dealers. Make sure to provide your treadmill model number to get the correct key.
What should I do if the safety key slot is damaged?
If the safety key slot or its internal contacts are visibly damaged, don't attempt to repair it yourself. Contact NordicTrack customer service for professional repair, as this involves electrical components that require proper training to service safely.
How often should I clean my NordicTrack safety key?
Clean your safety key and its slot monthly or whenever you notice the E7 error appearing. Regular cleaning prevents dust and sweat buildup that can interfere with the safety key's proper operation.
