I know an electronics technician who has repaired a couple of Trace
inverters for us for a very reasonable fee. Contact me off the list for
his contact info. <br><br>

BUT the replacement fans must draw approximately the same current as
the<br>
original fans because they are powered by a current source rather than
voltage<br>
source. i.e. If you use a fan that draws less than the fan
current, the voltage<br>
could rise too high. Some 12V fans don't have a problem
running at say,<br>
20+ volts DC BTW so might not be that big of a deal.<br><br>

No don't recommend replacing internal fans <br><br>
But I have installed external 120v muffin fans on the ends. <br>
Seal up the vents around the ends so it pulls air through. <br>
Hook the fans to the genny input. <br>
Quick and works well<br><br>

I recently assessed a 22 year old Trace 4024. During bulk charge
mode, I noticed that the charge would go from about 18A down to 5-6A
every 15-20 seconds, and then repeat the cycle. I observed this for
about 5 minutes relatively consistently I also noticed the body of
the 4024 was very hot, and I couldn't feel a fan moving air through
it. <br><br>
I put a fan on it and blew air over the body of the inverter, trying to
direct it through the machine. While I did that, I never observed
it drop out again over about 5 minutes, so I'm assuming that there is an
internal cooling fan that has gone out.<br><br>
It's been quite a while since I opened one of these up. Does anyone
know what's involved in replacing a cooling fan on one of these? Is
it worth it on a 22 year old inverter?<br><br>
Thanks in advance<br><br>
