Resistance Issues
Applies To
All Spinner Series Bikes
Issue
Increasing the resistance knob does not apply typical or no increased resistance to the fly-
wheel.
Cause
l
The brake pad-flywheel gap is out of specification.
l
Damaged brake pads.
l
The resistance knob shaft mechanism has failed and is not adjusting the caliper brake
pad arms.
l
Caliper strain gauge cable has either disconnected or is bad.
l
LPCA

failure.
l
Caliper strain gauge has failed.
Solution
Verify that the resistance knob shaft is varying the caliper brake pad-flywheel distance as the
resistance is varied from minimum resistance to maximum distance.
l
If not, verify the resistance knob and shaft operation, see
Increase the resistance to maximum and make sure the brake pad-flywheel gap is within spec,
see
"Brake Pad Adjustment" on page 12
.
Inspect the brake pads for physical damage. Replace if damaged, see
Verify that the console is reading torque. While pedaling, access the console service menu,
select the Torque parameter and verify that the torque varies with change in resistance level.
l
If no measure torque, make sure that the caliper strain gauge cable is connected to the
LPCA strain gauge port and that the cable is not damaged.
l
Replace the LPCA board.
l
Replace the caliper assembly, see
