[ICOM] Pro3 Fan Questions

[Bob Beatty]

I have just received a new Pro3 and am having some issues with the fan.

1.  Without keying the rig, the fan periodically comes on and runs for
about a minute and shuts off.  Is this normal?

2.  Today (7-26), the fan began to run whenever the rig was keyed and would
stay on from 30 seconds to 1+ minute.  By "keyed", I mean clicking the PTT
and letting up.  This operation seems excessive.  I thought the fan was
thermostatically-controlled and would only run when it got hot enough.

I do not find the fan action mentioned in the owner's manual and I don't
know if there is a user adjustment for what is happening.

Any suggestions, opinions, etc. are appreciated.
