Precor Error Code 27 Motor Current Too High

Mar 03, 2022

Applies to Treadmills

Overview

Error codes 27, 28, and 29 overview, see 27, 28, 29 Overview

Issue symptoms

The motor controller monitors the amount of current being used by the drive motor. Error 27 is triggered when the motor current increases to the maximum drive motor current (approximately 20 amps). The most likely cause is a worn running belt and deck. Less likely, but possible, is a faulty drive motor with a high current demand.

Troubleshooting steps

1. TRM700-XX, TRM800-14 & later
   1. If the Belt Rating is 1 or 0, replace the belt and flip (or replace deck.
2. TRM600-XX
   If the Belt Maintenance > Current (motor current) result is high (greater than 16 amps), inspect the condition of the belt and deck for wear.
   1. If dirty, clean the belt/deck and verify operation.
   2. If worn and in poor condition, replace the belt and deck (or flip deck).
3. TRM800-10 and earlier models
   Measure the AC input current under load.
   1. Clean the deck and belt.
   2. Connect a Clamp-on AC ammeter to the AC input hot wire.
   3. Then measure the AC input current while doing a manual workout between 7-8 mph and 0% incline.
   4. If the current is high (greater than 16 amps), Inspect the condition of the belt and deck. If worn and in poor condition, replace the belt and deck (or flip deck).
4. Replace the drive motor.
