Precor Treadmill Troubleshooting Error 17 - DBR Thermal Trip

Jan 02, 2022

Applies to

Treadmill 800.v2

Issue symptoms

This error monitors generated current being sent to the Dynamic Brake Resistor (DBR). When the drive motor is energized, and external forces cause it to turn faster than it is being driven, current is created. This current is sent through the MC to the dynamic brake resistor (DBR). When the MC perceives that enough current is being delivered to the dynamic brake resistor (DBR) to make it hot, this error is displayed and the treadmill comes to a stop.

The most likely causes for this are a runner at incline with a new deck and belt, a large runner at incline, or an exerciser pushing against the handgrips while forcing the belt with their feet.

Troubleshooting steps

1. If deck and belt are new, this failure mode will likely go away after a few months of use.
2. Allow the dynamic brake resistor (DBR) to cool down; reset MC status and monitor for repeat error.
