[Elecraft] cold/power on/ transmit on/pa hot! software glitch?

[Stephen Pearce]

After a month of so of minimal use my elecrafter k2 .. with 
the 100 pa has started to act oddly when powered on
The transceiver goes immediately to a mode with the pa
fan on and says it is over hot ...
if I tune then the fan powers down and the transceiver behaves itself.

I suspect this might be a software issue with the 
detection of temp by the pa thermistor ..
has anyone else had similar experience and 
can anyone suggest a fix?

Thanks

Stephen
