Walking or running your way to fitness is one of the most natural workouts you can do, and a treadmill offers the convenience of doing so in one stationary location from the comfort of home, in all weather conditions and at any time of day. So when there’s a problem with your treadmill, it can really feel like you’re getting nowhere fast. The treadmill problem troubleshooting tips below can help get you and your exercise machine moving again in no time.
Treadmill power not turning on
If the treadmill won't turn on, make sure the power cord is plugged in and that you’re using a single-outlet surge suppressor to protect against power surges and electrical interference. Check the safety key, and make sure it did not come loose from the console. You should also check the power switch to see if it's tripped; if so, wait 5 minutes and reset it.
