K2 Fan won't stop

[Dan Schieler]

Just had a nice CW qso at 80w with a fellow in Ca, but now the fan on my
K2 won't stop running.  The rig is completely cool, but yet the fan
keeps running on high.  When I started the QSO it was off.  Now even
after the rig shut off for a 1/2 hour, when I turn it back on, the fan
comes on as well.  In the control settings with PA menu, hitting display
shows Fan Hi, Fan Hi/LO and Fan Nor, switching between these settings
makes no difference at all, the fan keeps going at a high and noisy
speed.  Any ideas where to check for problems?
 
I don't recall what circuit/device triggers the fan to run.  Even if I
run in QRP mode, with the PA OFF, the fan is still running on high....
 
Thx
K5GUS
Dan

Dan:
   Check to see that the temperature setting is correct.  Go to the CAL
TPA menu item.  When the TPA is underlined, hold the MENU button for a
short bit and let it up.  The temperature setting will now be
displayed.  When the rig has been off for a long while, it ought to
read room temperature (in C).  If not, reset it by turning the tuning
knob.  I believe it has been reported that some people have found this
setting to have altered to its highest reading, causing the fan to run
all the time.  I have no idea why it should change, but the gremlins of
the world are always with us.

best wishes,
