[Elecraft] NO AUTO FAN ON KPA-1500

[Dick Dievendorff]

The turn-on temperature for fan speed 1 is 50 degrees C.  Fan speed
threshold temperatures are in the KPA1500 firmware release notes for version
1.87.

In earlier firmware, the fans did indeed come on at less than 50 degrees C.

The temp sensor is working. The remote software sees the temp. And I can
control the fans with the remote software. 

48c. Then I turned on the fans with the remote software.

When the auto temp feature in the amp working, the first fan came on at
about 40c

Just a couple of questions:

If the temperature sensor isn't working how are you measuring the
temperature?

What is the highest observed temperature with fans not running?
