Possible Remedies
1. Check the belt rating and current draw of the treadmill – replace belt and deck as
necessary.
2. Monitor minimum RMS line voltage with:
a. Treadmill at banner or welcome screen
b. Treadmill at 6 Mph with runner
c. Treadmill at banner, run at 6 Mph on neighbouring tread
d. If fluctuations of more than 15% are observed between banner case to runner at
6 Mph case OR if fluctuations of 5V or more are seen when running on a
neighbouring treadmill, request the club to have an electrician evaluate the
distribution wiring
3. Check the DB resistor temperature. If it is stuck ON it may be hot. If stuck ON, replace
both DB resistor and the Control Module.
