Feb 10, 2022

Applies to AMT12, all models

Overview

Error codes 70 thru 79 overview, see 70-79 Overview.

Issue symptom

The AMT12 flat belt system has a predetermined life span of 100,000,000 (100M) strides. The AMT12 maintains a stride count independent from the overall machine stride count. When this stride count reaches 90,000,000 (90M) strides, Error 78 is recorded in the error log and displays a message, alerting that the flat belts need to be replaced soon. Normal workout operation is still available. When the stride count reaches 100M strides, Error 79 is recorded in the error log and displays a message, indicating that the flat belts must be replaced. If this occurs during a workout, the exerciser will be able to continue the workout until ended. No further workouts will be allowed until the stride count is reset in the console after the belts have been replaced.

Troubleshooting steps

1. Replace all four flat belts (see Service Manual for procedure).
2. Reset the flat belt stride odometer.
