  krosarioAug 14, 2025
  If your Life Fitness Treadmill shows no power, first ensure the ON/OFF switch is in the ON position. Then, check if the power source is sufficient by plugging the treadmill into an appropriate circuit, ideally a dedicated 15 amp circuit in North America. Use a voltmeter to verify power at the outlet and reset the circuit breaker if needed. Also, inspect the power connections at the wall outlet and the machine to ensure they are properly seated. If the line cord is damaged, it should be replaced; contact Life Fitness Customer Support for assistance.

Why is the heart rate reading erratic on my Life Fitness Treadmill?
- A
  Ashley RamseyAug 21, 2025
  If the heart rate reading on your Life Fitness Treadmill is erratic or absent, start by wetting the belt transmitter electrodes to ensure they make good contact. Make sure the electrodes are lying flat against your skin. Clean the belt transmitter with mild soap and water. Ensure the belt transmitter is properly set up by initially bringing it within 1 foot of the receiver (in the console) until the heart rate is displayed, then extend the range to 3 feet.

Why is the maximum speed reduced on my Life Fitness Run CX Treadmill?
- K
  Kristin ReedAug 26, 2025
  If the maximum speed of your Life Fitness Treadmill is reduced, it may be because the user is pushing the striding belt, running faster than the belt's speed. Instruct users not to push the striding belt in either direction. Also, if the striding belt/deck malfunctions because the deck laminate is worn or the underside of the belt is glazed, replace both the belt and deck.
