Precor Error Code 05 Stuck Key in the Operated Position at Power Up

Sep 15, 2021

Applicable for All Precor consoles

Important: Error 05 has not been displayed on Precor equipment since 2003. It was replaced by the simpler "Stuck Key" message, and is not recorded in the error log.

Symptoms:
The power up test sequence has detected a key in the operated condition. A permanently stuck key inhibits the correct operation of the unit. Likely causes are liquids present on a touch sensitive display, or a key in the display housing is stuck in the operated condition. Less likely but possible is a failure on the upper PCA.

Troubleshooting steps to follow:

1. Check for visible liquid
2. Wipe off any visible liquid from the surface of the touch sensitive display.
3. Restart the unit. If error 5 is no longer present, the liquid was the cause.
4. Test the keypad
5. Turn off the unit.
6. Remove the keypad connector cable from the upper PCA.
7. Restart the unit, if error 5 is no longer present, the keypad is the cause. Note that the keypad is typically part of the display housing.
8. Replace the display housing to correct the problem.
9. Test the upper PCA
10. Turn off the unit.
11. Remove the keypad connector cable from the upper PCA.
12. Restart the power up sequence, if error 5 is still present, the upper PCA is the cause.
