[Elecraft] KPA500 fan won't shut off

[Kevin, N4TT]

Jerry:

Maybe clarify. I think Jack's concern is that your fan was running even
with the power off.  That's not the case, right? The fan just came back on
full when you turned the power back on?

Try Menu, scroll down to FAN CTL and make sure that say NOR. If it has a
number instead, you somehow accidentally set the fan on at that speed. Just
use the down arrows to get back to NOR. This is all done on the front panel
of the KPA500. Hope it helps.

73,
