Applies to Treadmills

Issue symptoms

The rotation of the LPCA(Lower Printed Circuit Assembly board) cooling fan is monitored. If the fan is not rotating, or rotating too slowly, an Error 14 will be logged. Typical symptoms include the heat sink by the fan can get clogged with dust and/or dirt, the fan connector/cable becomes disconnected or damaged, the drive motor cable routed such that it prevents the fan from turning, or the fan itself has failed.

Troubleshooting steps:

1. Visually inspect the fan.
2. Clear the error log.
3. Switch OFF unit.
4. Remove any debris from the fan.
5. Reset the motor cable as required.
6. Switch ON unit, test when running the belt.
7. Inspect the fan connector.
8. Switch OFF unit.
9. Inspect and reconnect the fan connector.
10. Visually inspect the drive motor cable for clearance away from the fan.
11. Visually inspect the fan for movement during operation.
12. If the fan does not move:
    1. TRMs built 2014 and later: Replace the fan. If the replaced the fan fails, replace the MCU(Moror Controller Unit, Motor Controller Module)
    2. TRMs built prior to 2014: Replace the MCU.
