[Icom] IC-910H heat/fan problem

[Ron Tivey]

Hello to all,

	I have a IC-910H with all the option installed.  I haven't had any
problems till today.  My wife being long winded was talking to a friend
for several minutes in 2M FM about 40W when the radio cycled off and on
when she keyed up.  I repeated this when I ran the radio on a dummy load
for a while.  The problem appears to be heat.  When the radio is
transmitting the fan will cycle from slow to fast until the PTT is
released.  Then the fan stops.  Seems to be ambient temp build-up during
tx/rx cycles.  Shouldn't the radio fan stay running until the temp drops
below a set point from a thermostat?  I never noticed this before so I
don't know it this is a problem with just my radio or a design problem. 
Anyone out there with an answer?  I don't what to send this radio to
ICOM only for them to say it's okay.  I would appreciate if someone with
a IC-910H could duplicate this test and forward a result to me.
