Troubleshooting Procedures
1. Set the treadmil
l’s on/off switch in the off position. Visually inspect the lift motor’s wiring and
connector for any broken or improperly crimped connections. With an ohmmeter, measure
between terminals 1 (white) & 5 (black) and 1 (white) & 6 (red) of the INCLINE connector.
Both readings should be approximately 12

(Ohms) for a 120VAC lift motor and
approximately 24

(Ohms) for a 240 VAC lift motor. If either reading is significantly high or
open replace the lift motor.
2. Disconnect the lift motor from the lift platform. If the lift tube or lift nut is jammed against the
motor housing, rotate the lift nut or lift tube away from the motor housing.


If the lift was jammed, please refer to Calibrating the Lift motor, and reattach the lift motor to
the lift platform.

3. Set the On/Off switch to Off and unplug the tread from the wall. Remove the MC from the
frame by loosening the four screws that secure it to the pan. Unplug all the connectors to
access the bottom of the MC, and snap it off. The fuse is located as shown in figure 6. Using
an ohmmeter, measure the fuse. If the reading is anything other than near 0
Ω
, replace the
fuse, reinstall the MC and all connectors, and retest. If the fuse opens again, troubleshoot
the motor for movement or shorted wiring.
