4. If the incline moves normally skip to step 7.
5. If the display indicates that the incline should be moving and the incline motor does not
move and AC line voltage is present, skip to step 12.
6. If the display indicates that the incline should be moving and the incline motor does not
move and AC line voltage is not present, replace the power control module.
7. With the incline above 0%, connect an AC voltmeter between terminals 1 & 5 of the
INCLINE connector. See Diagrams 5.3 and 5.4. Set the treadmill in the manual program and
press the INCLINE
240 Vac). Note that the AC line voltage reading will only be present before an error condition
is displayed.
8. If the incline moves normally skip to step 11.
9. If the display indicates that the incline should be moving and the incline motor does not
move and AC line voltage is present, skip to step 12.
10. If the display indicates that the incline should be moving and the incline motor does not
move and AC line voltage is not present, replace the power control module.
11. The incline is moving normally in both directions, there is either is not an incline problem or
the problem is intermittent. Intermittent problems are often caused by poor connections or
wiring problems.
12. Set the treadmill's on/off switch in the "off" position. Visually inspect the incline motor's
wiring and connector for any broken or improperly crimped connections. With an ohmmeter,
measure between terminals 1 & 5 and 1 & 6 of the INCLINE connector. Both readings
should be approximately 12Ω. If either reading is significantly high or open replace the
incline motor.
key. The AC voltmeter should read AC line voltage (either 120 Vac or
