[Elecraft] HI TEMP error

[Wim van der Zwan PA2AM]

hi,


I have the last week problems with the K-3. 

I will get a msg HI TEMP on display ( by K-3 ON ) , the K-3 is cold with room temp. abouth 15 degrees C. 

with the msg HI TEMP the PA will bypass and can only use the low power PA ( 15 watts ) , the Fan will gooing on 

by menu config     PA-TEMP ,  I see a temp switching from - 100 C and -127 C continuing a differents value. 

in begin this week the problem whas over after 30 min warming up, but now the K-3 will stay in protection, no high power en fans on.. and still the msg HI-TEMP


The K-3 is here    serial no:    576 
software                          :    04.14

What thit I do:
I reset this week the K-3 with the standard values but the problem will stay....
I thit calibration the hole serie   5 watt, 50 watts en 1 Mw calibration, everything is ok with this calibration
re-calibrating the PA Temperature Sensor 
After I set PA TEMP to "R ONLY" instead of "T AND R",



I hope that somebody can give me a solution???
