Saris H3: Common Issues

by Sarah D February 20, 2022

What goes wrong with the Saris H3 Direct Drive Turbo Trainer?

1. Top Hat Issue

Overtightening of the axle end caps can cause the top hat spacer to snap and crumble (like the image below).

The top hat sits behind the Freehub. There is no torque spec for the end cap. It should be hand tightened. If your top hat has snapped/crumbled then this can be replaced, we stock these to sell - link here

2. Belt needs cleaning or replacing

After time you may find that the belt needs replacing or cleaning.

If you have a Saris H3, then you will have a smooth belt. The Saris product code is: SAR9734T. Please see link below

3. Power Supply Issue

A common issue with the H3 is the status light on the unit is not coming on when plugged in even when the plug indicator showing green. This issue is usually caused by a faulty power supply.

Even though it is showing green light it may not have enough power output. It should generate 40V. Have you got a volt meter to test the output?
