2 Set the treadmill’s speed at 7-8 m.p.h. and the incline at 0%. Walk
on the treadmill and observe the average A.C. current reading.
Typical average A.C. current readings on a new running belt and deck
are between 8 to 12 amperes. average readings (those read by a
digital meter) could be as high as 20 amps, even on a new belt and
deck.
3 If the average current reading approaches 20 amperes, the running
belt should be replaced. The running deck should be flipped or
replaced if the running deck has been previously flipped. See
Procedure, Running Belt and/or Deck Replacement (on page 111) for running
belt and running deck replacement.
4 If the average AC current readings are greater than on a new running
belt and deck combination but not approaching 20 amperes, the
reading will give you an indication of the running belt and deck
combination’s general condition.
NOTE: Repeat the amp draw test after replacing a running belt
and deck.Damage to the lower control module can occur if the
unit had been run in an overload/high current condition for
prolonged periods of time. This type of damage would not
generate an error code, but would cause the breaker to trip
intermittently. An amp draw test will catch this condition.
