What to do if my NordicTrack C1650 power does not turn on?

  First, ensure the power cord is properly plugged into an earthed outlet. If using an extension cord, it should be a 3-conductor, 14-gauge (1 mm[2]) cord no longer than 5 ft. (1.5 m). Also, verify the key is inserted into the console after plugging in the power cord. Finally, check the power switch on the treadmill frame near the power cord; if it's protruding, wait five minutes, then press it back in to reset it.

What to do if NordicTrack Treadmill walking belt slows when walked on?

  The walking belt may slow down if it is overtightened. Remove the key and unplug the power cord. Using the hex key, turn both idler roller screws counterclockwise, 1/4 of a turn. When properly tightened, you should be able to lift each edge of the walking belt 2 to 3 in. (5 to 7 cm) off the walking platform. Your treadmill features a walking belt coated with high-performance lubricant. Never apply silicone spray or other substances to the walking belt or the walking platform unless instructed to do so by an authorized service representative. Such substances may deteriorate the walking belt and cause excessive wear.
