Atsu,
did you check the fans ?
--------
Connect a power supply to your K3 and test the fans and KPAIO3 interface
control as follows:
- Press the POWER button to turn the K3 on.
- Hold CONFIG to select the Configuration menu, then turn VFO B to KPA3.
Normally, the display will
indicate NOT INST (not installed).
- Turn the VFO A knob to PAIO ON, then turn it further to PAIO TST. When
moving between ON and
TST, you should hear a relay click on the KPAIO3 board. If you don't,
press the K3 POWER button to
switch it off, then on again and retry the test.
- Turn the VFO A knob on past TST to FN1, then FN2, FN3 and FN4. The
fans should start turning at
FN1 and increase speed as you continue to FN4.
Turn the K3 off and disconnect the power supply.

Subject: [Elecraft] K3 HI-TEMP ALARM
Hi Elecrafters!
I have problem on my K3/100 (S/N3050, factory assembled).
When I transmit more than 12W(means hi power amp on) within about 30min
after mains power on, HI-TEMP alarm occur and equipment is forced to set 5W.
No problem at all when hi-power amp is through ( Po<12W ).
Any idea?
Thanks in advance
73, Atsu JE1TRV
