Procedure 5.1 - Troubleshooting the Keypad and Upper PCA
If the function keys on the electronic console are unresponsive, the problem may be either the
upper PCA or keypad.
Procedure
1. Set the circuit breaker in the “on” position.
WARNING
Before continuing with this procedure, review the Warning and Caution statements listed in
Section One of the Commercial Treadmill Service Manual.
2. If the treadmill powers up and functions normally until a particular key(s) is pressed, skip to
step 8.
3. If a Stuck Key message is immediately displayed when the treadmill is powered up,
continue with the next step.
4. This condition may be caused by either the keypad or upper PCA. Set the circuit breaker in
the “off” position. Remove the two screws that retain the reading rack and remove the
reading rack. Remove the eight screws that retain the display face, two are under the
reading rack. See Diagram 5.1.
