PUSHBUTTONS DO NOT FUNCTION
Symptoms:
The symptoms you see will vary depending upon the
cause of this issue.
Improperly installed, or loose, Control/Display
Board:
What you see depends upon which button is
in contact with the cover.
The output meter may not flash upon power up of the
power supply.
The output level may also run up to 100%, or down
to the power supply’s minimum output level.
If you press the pushbutton(s) that is in contact with
the cover it, will typically not depress or spring back.
Failed Control/Display Board:
In this case the
symptoms will be dictated by what has failed on the
board.
If a pushbutton has failed or broken, the symptoms
may only affect that pushbuttons function.
